This summer
Temperatures in many parts of the country hit a historical record.
Since the ambush
Only air conditioners, fans and cold drinks can "continue life"
But when it comes to "cold drinks", many parents wave their hands again and again.
High in sugar, oil and calories.
Better eat fruit.
After all, summer
It is a good season to eat fruit.
not only that;nay
There is a way to eat fruit.
But it’s better than "cold drink"
that is
"Frozen" to eat!
Frozen fruit is better than you think.
Many people say that since eating frozen fruit, even ice cream is inferior!
The delicious ice cream mainly depends on fat, protein and sugar. Wherein fat and protein provide mouthfeel.
Protein will seize the "water" molecules in sugar water to form bound water; Fat is broken up to form small fat balls, which are combined with protein and water, and they work together to form a smoother and more delicate taste.
This kind of taste can also be found in frozen durian.
Moreover, even though durian is already the king of calories in fruits, reaching 150kcal/100g, it is just a low-fat product compared with ice cream.
In addition to durian, there are bananas, which are also comparable to ice cream.
At the same time, researchers in many countries believe that super-processed foods (ice cream, chocolate, cakes, potato chips) and so on are positively related to obesity. High calorie is not the main problem of these foods. The bigger problem is that they are often high in sugar, fat and salt, and rarely provide diversified nutrition. They can be obtained everywhere and are particularly easy to eat more.
Delicious, nutritious and not fat, frozen fruit is really worth a try.
Recommended frozen fruit "red list"
Frozen fruit is delicious, but not all fruits are suitable to be thrown into the refrigerator.
Only those with high sweetness (ripe), fine texture, delicate and smooth taste of ice cream or cool and refreshing smoothies are suitable for freezing.
Specifically recommend several models for everyone:
Frozen durian can be described as a "perfect substitute" for dessert. protein and fat are high, so it will taste like ice cream, but durian is also high in sugar. Children who control their weight should not be greedy!
one
Banana is high in potassium and low in sodium, which is the best choice for quick energy supplement. The taste of frozen bananas is also very similar to that of ice cream, and the taste is soft and waxy like adding cream. However, it needs to be reminded that frozen bananas should be peeled before freezing, otherwise they will be frostbitten.
2
Mango has a high carotene content, 45 to 104 times that of apple, which is helpful to improve night blindness, and it is also a selenium-rich food. The frozen mango has a more fragrant aroma and a fine and soft taste. However, it is best to peel mangoes after freezing, and it is best to choose ripe mangoes for freezing.
three
Jackfruit is a high-potassium food. After freezing, its taste is crisp and waxy, so it is worth a try. However, the sugar content of jackfruit is very high, so children who need to lose weight should control their consumption.
four
Croissant honey is a representative of sweet but not fat fruit. It tastes sweet and refreshing, but in fact it is not high in calories. The taste of frozen croissant honey is very similar to that of sandwich ice cream, with crisp outer layer and soft inner core. Children who are greedy for "sandwich ice cream" are worth a try.
five
Grapes are rich in a variety of fruit acids to help digestion, and high levels of vitamin C and anthocyanins are also beneficial to the body. Frozen grapes taste like smoothies, and after melting a little, they look like jelly.
six
Litchi has a high content of vitamin C, which is comparable to citrus fruits. Frozen litchi mixed with pulp with ice residue is very chewy. It should be noted that the sugar content of litchi is also very high. Although a considerable part is fructose, the total amount of glucose and sucrose is not low. Children who need to control sugar should eat less.
seven
Watermelon, a fruit with moisture in off the charts, is a proper popsicle after freezing. It has a rustling taste and melts in your mouth and is full of juice.
eight
Papaya must be softened before freezing. Soft papaya is frozen for one night, slightly warmed up, soft and waxy, with delicate pulp, and there is no ice residue in it, which is biased towards the dense taste of ice cream. After freezing, the fragrance of papaya became more and more full, and the sweetness became refreshing.
nine
Tips:
Fruits with high sweetness and good flavor are delicious when frozen, and the sweetness after freezing is not so greasy. Tropical fruits such as durian, mango and pineapple are generally suitable for frozen eating; On the contrary, the more sour the fruit, the less suitable it is to be frozen. Don’t try fruits like plums, apricots and oranges easily.
Fruits with high fructose content are sweet at low temperature, such as grapes and watermelons, which are sweet and refreshing after freezing; Fruits with high sucrose content have similar sweetness at any temperature, such as dates and peaches, which will not be sweeter after freezing.
There are requirements for "frozen" fruits
Although frozen fruit is delicious, improper operation may "hurt" your body!
Many parents worry that their children think that eating cold food will cause diarrhea. But in fact, sometimes children will feel uncomfortable after eating cold food, which may not be caused by "cold", but there may also be the following reasons:
Food intolerance (or allergy)
Some children have gastrointestinal discomfort after eating certain foods, which is largely due to food allergies. In summer fruits, mangoes and pineapples are allergic foods. In addition to allergies, there may be food intolerance. Some children’s intestines and stomach can’t digest and decompose certain foods, which will cause discomfort such as flatulence, diarrhea and abdominal pain.
Eat too much at once
Eating frozen fruit in summer can cool off the heat and quench thirst, so it is easy for children to binge and eat if they are not careful. But in fact, whether it is warm or cold, eating too much is easy to cause indigestion.
Personal constitution
Some children have a fragile stomach. If they have irritable bowel syndrome and are prone to gastroenteritis, eating cold food may cause stomach upset.
In addition, there is one of the most important reasons that must be paid attention to when freezing fruits, that is-
Food is contaminated by germs.
In the process of fruit pretreatment, frozen fruit and thawing, food comes into contact with some microorganisms, causing virus, bacteria and protozoa infection, causing abdominal pain and diarrhea in children.
Therefore, I suggest you:
Pay attention to the separation of raw and cooked in pretreatment.
Use clean chopping boards and drinking water when peeling and cleaning. Cutting tools and chopping boards should be separated from raw ones.
If there is room in the refrigerator, you can use a freezer drawer to store frozen fruits. If there is not such a big place, be careful not to put frozen fruits and raw meat products together.
Do a good job of packing and sealing.
Although the microbial reproduction of fruit is slow after freezing, it can be preserved for a long time in theory. However, if the fruit is frozen for too long, it will produce large ice crystals, and many fruits will easily taste bad, which will affect the taste.
Don’t freeze and thaw repeatedly
Repeated freezing and thawing is not only a serious nutrient loss, but also prone to deterioration.
Finally, the frozen fruit can be eaten after 5 to 10 minutes.
Eating fruit should also be divided into time periods
Fruit itself contains different enzymes. If you want enzymes to have different effects in the body, you should also choose the most suitable time to eat.
Don’t eat too sour on an empty stomach.
People with poor gastrointestinal function should not eat fruit in the morning. Bananas are also not suitable for eating on an empty stomach, which will speed up the movement of the stomach and increase the burden on the heart.
Eating fruit between meals can quickly supplement vitamins.
When eating fruit between meals, fructose and glucose in the fruit can be quickly absorbed by the human body. Pineapples can be eaten after lunch, and watermelons are best eaten two hours after meals.
Don’t eat a lot after dinner.
Eating fruit 1 hour after a meal helps digestion, and you can choose fruits with high organic acid content such as pineapple and hawthorn.
But don’t eat a lot of fruit after dinner, which is not good for digestion, and it is easy to turn the sugar into fat and accumulate in the body because of eating too much.
Homemade fruit ice cream
If you want to make ice cream for your child, you must remember the following "formula":
Frozen fruit+yogurt+banana+whipping
Mix frozen fruit, yogurt and bananas, whip them finely, then put them into a mold, and freeze them for 30-40 minutes, and they will become home-made fruit ice cream!
Passion fruit mango flavor ice cream
350g frozen mango meat +60g frozen passion fruit juice +1 banana at room temperature +100g frozen thick yogurt.
Qing ti mi gua Wei ice cream
350g frozen honeydew melon +250g frozen green extract +1 banana at room temperature +100g frozen thick yogurt.
Frozen fruit, in the way of delicious, cool and not fattening, prolongs the taste period of seasonal fruits and also prolongs the happiness in summer.
Parents may wish to give their children a try when they have time!

BEIJING, Nov. 8 (Sweet Dong Hanyang) A few days ago, a finless porpoise was floated in Dongting Lake, Yueyang, Hunan Province, with a 20-cm incision on its belly surface and two bricks falling from its tail with a rope. The staff decided that the finless porpoise was either killed and dumped.
In the spring of 2012, there was a shocking death of finless porpoises in Dongting Lake, and a total of 12 finless porpoises died.
The finless porpoise is known as the "natural smiling spirit". However, the data shows that as of July 2018, the number of finless porpoises is only about 1012, which is less than 60% of that of giant pandas. Now, another "spirit" has disappeared.
"70% of the world is covered by water, and our planet is a blue planet." Behind this well-known saying, more than 200,000 species of aquatic animals around the world continue to face survival crisis. Who is the chief culprit of the crisis?
Data map: finless porpoise.
Suspect number one: human
M.O.: Hunting, slaughtering or keeping in captivity
The 2009 documentary "Dolphin Bay" exposed the human who laid hands on dolphins to make money. It is reported that every dolphin caught can sell for up to $150,000.
However, the blood in Dolphin Bay "can’t wake people who pretend to sleep". In 2019, the Japanese government officially withdrew from the International Whaling Commission (IWC) and restarted the commercial whaling activities suspended for 31 years.
In September, 2019, fishermen’s fishing boats in Taiji Town, Wakayama set sail again. The hunt will last until April 2020.
Statistics show that during this time of year, fishermen in Taiji Town will kill 2,000 to 3,000 dolphins. However, scientists have said that dolphin meat is not excellent in taste and nutritional value, and even its mercury content is still high, which is not good for health.
The hunter’s hand extends not only to the dolphins.
In 2014, three men and women stole 10,375 eggs from the Mexican turtle reserve, which has long been listed as an endangered animal.
In 2018, a "whale prison" appeared in the Russian Far East, where 90 beluga whales and 11 killer whales were imprisoned, of which 13 beluga whales were under one year old. Because of human imprisonment, killer whales that could have lived to be 100 years old in nature, most of them can’t live to be 30 years old in captivity.
At present, the Russian prosecutor has filed a criminal case against the relevant personnel for "illegal fishing of aquatic biological resources", and the whales in the "whale prison" will be released in three batches.
In October 2019, the staff of the protection agency "Dolphin Project" also discovered two dolphins that had been kept in captivity for 15 years in Bali and were badly abused. Because dolphins excrete a lot, the swimming pool in which they are kept is like a "toilet bowl". In order to decontaminate, the hotel adds a lot of chlorine to the water.
Among them, the dolphin named Deva was obviously insane, and another dolphin, Johnny, was blind.
Fortunately, with the help of the staff of the Dolphin Project, they will regain their freedom and return to the sea.
Suspect number two: plastic
Modus operandi: Good at "camouflage" and easy to be eaten by animals.
In Sardinia, Italy, the body of a pregnant sperm whale was washed ashore. In its belly, plastic garbage weighing 22 kilograms was found.
Marianne, a dugong cub from online celebrity, Thailand, died of illness. Officials say it has a small amount of plastic garbage in its stomach.
There are nearly 30 undigested plastic bags and other plastic wastes in the stomach of the stranded whale carcass in Norway.
Plastic fibers have also been found in the stomachs of crabs in Thames, England. They may have accidentally eaten balloons and sanitary napkins … …
Plastic seems to be the terrible "number one killer" in the water. According to statistics, 90% of marine garbage found on the global coastline is related to plastic products. Bottles, straws and food packaging have become "stains" floating in the ocean.
Because most animals can’t tell plastic garbage from food, every year, 34% of leatherback turtles die by mistake and swallow plastic bags as jellyfish. And some fish are easily attracted by the smell of dimethyl sulfide emitted by plastic soaked for a long time, and mistakenly regard it as prey.
The allen macarthur Foundation of the United Kingdom has predicted that by 2050, the weight of plastic waste in the ocean will catch up with the weight of marine life. What is even more frightening is that plastics cannot be completely degraded in seawater.
Suspect number three: noise
M.O.: Interfering with the echolocation system, causing a "suicide wave" of whales.
On December 8, 2014, six or seven sperm whales lay motionless on the shore of Paarala Sea Beach in York Peninsula, South Australia.
The locals said, "I think it’s too late to save them. At 8 o’clock in the morning, one of them was still wagging its tail, but now it’s not moving … …”
According to reports, these whales were disturbed by sonar and disoriented before being washed ashore.
However, this is not a case. Noise has become a major suspect in killing them.
In 2009, nine 12-meter-long sperm whales ran aground on the beach in Puglia, Italy, and five of them died, which may be caused by the noise of military exercises or the exploration of seabed deposits.
In July 2002, 66 pilot whales ran aground in Cape Cod Snow, Massachusetts, USA, for the same reason as sonar experiments.
In May 1996, 14 swordsmen whales ran aground on the Greek coast, which is believed to be related to a NATO exercise of the US military … …
Coled, deputy director of the French La Rochelle Marine Mammal Research Center, once pointed out that the acoustic waves emitted by the sonar and echo sounders of warships and the noise of underwater explosions will cause the echo positioning system of whales to be disordered, which is the main reason why whales collectively rushed to the beach.
Animals can’t speak, who will speak for them?
Who is chasing these natural "spirits" and creating one tragedy after another?
In order to protect human partners, many countries and regions have been acting.
China, Britain, the Netherlands and other countries and regions have successively issued plastic restrictions;
Canada has specially set up a coastal guard to protect the marine environment;
The United Nations has adopted relevant resolutions, proposing that the underwater noise generated by human activities … …
Data Map: A poster created by Christian Waters. On the poster, you can see that the turtle’s shell is hollowed out, its body is full of garbage, the sea lion is suffocated by a plastic garbage bag, and the sea fish suffocates after swallowing fine particles. Image source: WWF website.
Documentary director rob stewart has witnessed the bloody scene of illegal whaling, and has since stopped aiming at the dreamy underwater world. Many of the information he photographed on the impact of illegal shark fin trading, after being made public, directly promoted the process of the Costa Rican government’s introduction of relevant laws.
Christian Waters, an advertising designer, saw that there was a lot of garbage left on the beautiful beach, so he began to study the influence of marine garbage on animals, and finally created a public service advertisement, which was promoted by the World Wide Fund for Nature (WWF).
Waters said that animals can’t speak, so humans must speak for them.

On September 2nd, Huawei ECG App (Huawei ECG Analysis Prompting Software) obtained the CE MDR medical device certification of the European Union, and obtained the pass to enter the markets of the European Union and European Free Trade Area countries. At present, Huawei ECG App has obtained the market access qualification of 33 European countries. In the future, consumers in Europe will be able to use ECG App for single-lead ECG measurement in HUAWEI WATCH GT 3 Pro.
In response to this news, Wareable, a foreign technology website, believes that Huawei, as one of the giants in the smart watch industry, has obtained CE certification for its ECG App, which is a great improvement for Huawei’s development ambition and enables it to compete with Apple and Samsung internationally.
Equipped with high-performance ECG sensor, the heart health guard is upgraded.
Electrocardiogram (ECG) is one of the most commonly used clinical examination methods, and it is also a graphic record of cardiac electrophysiological activities, which hides subtle changes about the heart. In many health problems, ECG monitoring can help users identify irregular heart rhythm, and play a role in reminding early detection, early diagnosis and early treatment. For the ECG monitoring function, as early as 2020, Huawei has launched the first Huawei WATCH GT 2 Pro ECG model that can accurately record ECG data, and then launched the Huawei WATCH GT 3 Pro smart watch equipped with ECG analysis prompt software to support atrial fibrillation and premature beat risk screening.
Huawei WATCH GT 3 Pro ECG signal acquisition technology has been upgraded. The PVD coated electrode on the curved lens of the watch can better fit the skin and improve the quality of ECG signals. Equipped with a high-performance ECG sensor, it works in cooperation with Huawei ECG App. You can collect ECG signals for 30 seconds by touching the side electrode of the watch with your fingertips, and the generated ECG report can be viewed directly at the watch end. After a single measurement, the data can be synchronized to the mobile phone side in real time, and the paid interpretation service of doctors in the top three hospitals in China can be provided to give accurate ECG interpretation results and health care suggestions.
Medical institutions cooperate in depth to protect health in all directions.
Huawei has been deeply involved in the health field for a long time, and has successively launched a series of health management functions and monitoring functions on smart wearable products to help users actively manage their health. Huawei WATCH GT 3 Pro takes TruSeen5.0+ new heart rate monitoring technology as the core, brings a brand-new upgraded multiple health detection system, and cooperates with more professional medical institutions to comprehensively care for users’ health.
Through cooperation with 301 Hospital, Huawei initiated a heart health research project and a sleep apnea research project. Based on WATCH GT 3 Pro high-performance ECG and PPG sensors, it can finely identify heart problems such as atrial fibrillation, premature ventricular beats and premature ventricular beats, and can also intelligently identify information such as sleep, HRV, blood oxygen and heart rate, make multi-parameter fusion judgment, screen the risk of sleep apnea, and provide suggestions for improvement in different levels. In addition, based on various physiological parameters of Huawei WATCH GT 3 Pro, tongji hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology and 301 Hospital jointly launched research in the field of respiratory health to identify the risk of lung infection.
When Huawei WATCH GT 3 Pro was listed in China, Huawei ECG App had already obtained the national second-class medical device certification and achieved good market feedback. This time, Huawei ECG App and HUAWEI WATCH D wrist ECG and blood pressure recorder have obtained CE MDR medical device certification from the European Union, which once again confirms Huawei’s efforts and achievements in the health field. In the future, Huawei will continue to bring more accurate health monitoring functions and provide users with all-round health management.

At 12: 12 on January 19th, China Academy of Launch Vehicle Technology, affiliated to China Aerospace Science and Technology Corporation, successfully launched the Long March 11th solid launch vehicle with one arrow and six stars, which was the first time that China’s solid launch vehicle provided launch services to international users.
People’s vision
Not long ago, American Space Exploration Company’s Falcon heavy rocket was successfully launched for the first time, and a Tesla electric sports car was sent into space. This gimmick has attracted the attention of the public, and the technical characteristics of the Falcon heavy rocket have also caused a heated discussion in the global space industry and pushed commercial space into the public eye.
So, what changes will commercial aerospace bring to the human space field? What impact will it have on China Aerospace?
During the "Thirteenth Five-Year Plan" period, the total space industry market in China will reach 800 billion yuan.
In recent years, China’s commercial space activities have continued, and good news has spread frequently. If 2015 is the first year of China’s commercial aerospace development, then it can be said that commercial aerospace has ushered in spring in 2018.
In January this year, the Long March 11 solid launch vehicle was launched for the first time, which means that China’s solid launch vehicle began to provide launch services for international users.
Yang Yiqiang, commander-in-chief of the Chang 11 rocket, believes that "the success of the launch mission means that the commercial launch service process and configuration of the Chang 11 rocket will be further improved, which will provide more and better choices for the launch of many commercial satellites."
"Commercial aerospace is a market-oriented aerospace activity with a commercial profit model." Zhang Qin, vice president of the Fourth Research Institute of China Aerospace Science and Industry Group, thinks.
According to the Aerospace Report released by the American Aerospace Foundation in 2016, the global aerospace economy in 2015 reached 335.3 billion US dollars, of which commercial aerospace accounted for 76%. According to experts’ prediction, by 2020, the global space industry market will reach US$ 485 billion, corresponding to the China market, which will reach 800 billion yuan during the 13th Five-Year Plan period.
For this reason, it is becoming a unanimous choice for all countries in the world to find a suitable business operation model and expand and share the valuable "cake" of commercial aerospace.
Some private enterprises in China have actively participated in commercial aerospace. In January this year, Beijing Blue Arrow Space Technology Co., Ltd. signed a rocket launch service agreement with Danish enterprises, which is the first commercial rocket launch service order in the international market undertaken by domestic private commercial aerospace enterprises.
"The core advantages of private commercial aerospace are rapid decision-making and rapid technical iteration." Zhang Changwu, CEO of Beijing Blue Arrow, said that he will focus on verifying the reliability of technology in the next two years, and introduce a more perfect competition mechanism to reduce costs through wider selection of materials and more open technical cooperation.
In addition to commercial launch, in the field of space tourism, private commercial space flight has also made new progress. Beijing Golden Ocean Aerospace Company has previously demonstrated China’s first commercial skydiving suit. According to the developer, the suit has the functions of vacuum protection, thermal protection, communication between heaven and earth, positioning and so on. At present, it has passed the laboratory simulation test and can be used in complex environments such as stratosphere and space.
Previously, China Aerospace Science and Technology Rocket Technology Co., Ltd. raised 1.2 billion yuan of social capital in the A round of capital increase, which injected a strong impetus into commercial aerospace and also played a good demonstration role. The investor’s representative lamented: This subverted the previous impression that scientific and technological personnel were "chasing" investors with projects, and fully reflected the charm of "hard technology" innovation.
Up to now, China has successfully launched dozens of commercial satellites. In 2018, China will also make efforts in many fields of commercial aerospace. Yin Liming, president of Great Wall Company, a subsidiary of China Aerospace Science and Technology Corporation, said that in 2018, Great Wall Company will ensure the completion of domestic commercial launch missions such as Hongyan’s first star, No.1 01 star and global change scientific experimental satellite.
"Commercial aerospace, as a new format with strong technological innovation, high economic quality and efficiency and both military and civilian attributes, is an important carrier for implementing the national integration of defense and civilian technologies strategy and maintaining and increasing the value of state-owned assets, and is an extremely important and new growth pole for China’s economic development. Under the background of economic and technological globalization, highly developed commercial aerospace is one of the important symbols of world-class aerospace companies and aerospace powers. " Yang Baohua, deputy general manager of China Aerospace Science and Technology Corporation, believes.
According to industry estimates, for every dollar invested in the commercial aerospace field, it can boost investment of 7 to 14 dollars.
The commercial aerospace model can meet the needs of customers with low cost, high efficiency and high reliability.
"The commercial aerospace model can meet the needs of customers with low cost, high efficiency and high reliability, which has an important role in promoting the rapid development of space tourism and even the entire space technology." Pang Zhihao, executive editor of International Space magazine, said.
Liu Shiquan, deputy general manager of China Aerospace Science and Industry Group Co., Ltd., introduced the Falcon — The 9 "rocket has lowered the price of commercial launch by an order of magnitude. The same falcon — 9 "rocket, developed by NASA, costs at least $1.3 billion, while commercial companies only spend less than $400 million.
While the cost is reduced, the efficiency is also obviously improved. Liu Shiquan said that the first is to shorten the development cycle, "Falcon — 9 "It took only four and a half years from design to first flight; Secondly, the acceleration of technological innovation, "Falcon — 9 "A series of reusable rocket tests were carried out, and both land and offshore platform recovery tests were successful. "Commercial aerospace management institutions have implemented flat management, which has greatly shortened the management chain."
Liang Jiqiu, chief designer of Kuaizhou rocket of China Aerospace Science and Technology Rocket Technology Co., Ltd., said that in international commercial launch, the asking price of a rocket carrying a kilogram load is 25,000 to 30,000 US dollars, while the price of Kuaizhou 11 per kilogram load is only 10,000 US dollars. Through scientific and technological innovation, the take-off quality of Kuaizhou series rockets is reduced by about 20 tons compared with similar products, and this alone can directly reduce the launch cost by more than 10 million yuan. This makes this series of rockets truly a "commodity", not just a "product".
Commercial rockets with high cost performance will become "space vehicles", making it possible for ordinary people to travel in space.
As an ordinary person, what services can you enjoy in commercial aerospace?
Dr. Zhang Baoqing from Beijing Institute of Aerospace Information and Information believes that navigation satellites are obviously the closest service to consumers. In China, Beidou satellite navigation system attaches great importance to the consumer market, and Beidou navigation service has been applied to quite a few types of mobile phones. The industry believes that Beidou will achieve the annual output value target of 400 billion yuan in 2020.
High-resolution Earth observation constellation can be used to detect the changes of oil and coal production, transportation and storage, monitor the operation of large power plants, and provide objective and accurate decision-making reference data for energy enterprises.
Zhang Yong believes that cost-effective commercial rockets will become "space vehicles", opening the door to space travel for everyone, and ordinary people may also have a chance to travel in space.
"So far, China’s aerospace data application industry chain has not yet formed, and the depth of space resource value mining is not enough." In the view of Li Jinxiang, deputy chief engineer of China Electronics Technology Group, China’s commercial aerospace can do better. "At present, the commercial distribution, sales and data classification standards of aerospace data are not clear, which makes aerospace data scattered in various departments, resources are difficult to share, and applications are in a fragmented state."
Li Jinxiang suggested that relevant national policies and regulations on the commercial application of national commercial aerospace data should be promulgated as soon as possible, military and civilian aerospace resources should be developed as a whole, and a national-level aerospace data application service system should be established, so that the aerospace industry can explore a business operation mode that is closer to the people, serves life and is profitable.
Relevant experts also agree to speed up the legislation of commercial aerospace, break the shackles of commercial aerospace development through legal system innovation and governance mechanism reform, and ensure that different market players are equally protected by law.
Yang Tianliang, a researcher at Sanya Research Center, Institute of Remote Sensing Earth, Chinese Academy of Sciences, believes that the development ideas and specific paths of commercial aerospace must be considered in the context of integration of defense and civilian technologies’s development. We should not only change our concepts and realize that space technology and industry can serve both national defense and people’s livelihood, but also formulate policies and measures to promote the development of commercial space and support the development of private space enterprises.
The price of fruit has gone up sharply this spring. According to the relevant data of the Ministry of Agriculture and Rural Affairs compiled by Zhuo Chuang Information, the wholesale price of fruits from January to April in 2022 was higher than the average price in the past nine years, and it showed a continuous upward trend.
From the place of origin to the dining table, fruits have to go through the stages of fruit farmers’ picking, packaging and purchasing, loading and transportation, wholesaler sales, etc., and finally reach the fruit shop at home. Qianjiang evening news Hour reporter interviewed producers, wholesalers, logistics drivers and store operators, trying to explore the deep-seated reasons behind these links.
Many people are concerned about when the price of fruit will come down. According to the prediction of fruit farmers and wholesalers in producing areas, with the coming of summer fruit ripening season, the wholesale price of fruit will soon fall, and the price of retail stores will naturally fall.
Due to climatic reasons, the reduction in production and the sharp drop in imported fruits cannot fill the gap.
Most of the fruits in this season are from Yunnan, Hainan and other places, because the reduction in production has led to an increase in wholesale prices.
According to Hong Lianggang, the wholesaler of Hangzhou Fruit Wholesale Market, the price of wogan rose from 4 yuan to 11 yuan, honeydew melon from 12 yuan to 20 yuan, mango from 4 yuan to 10 yuan, and the most outrageous thing was watermelon. A while ago, the price of watermelon rose from 6 yuan to 20 yuan.
Chen Ying (pseudonym), who is purchasing fruits in Hainan, explained the reason to qianjiang evening news Hour reporter: "The winter in Hainan this year is particularly long. Due to the influence of cold air, the output of lotus spray, Guifeimang and litchi here has decreased a lot."
Mid-May is the season when a large number of lychees are listed in Hainan. In previous years, the local wholesale price was only five or six yuan a kilogram, but this year, the wholesale price of lychees rose to 14 yuan a kilogram, and the price doubled 1.5 times.
Before the local fruits were ripe for the market, the output of foreign fruits was reduced. In the past, this situation also happened. The solution for wholesalers was to fill the gap with imported fruits.
But this year, the number of imported fruits has also dropped sharply.
At Hong Lianggang’s wholesale point, the sales of imported fruits accounted for 30% of the total sales in previous years, and now it has dropped sharply to 10%.
The origin of imported fruits this season is mainly Southeast Asia. Last year, 7.5 kilograms of mangosteen with a box of 200 pieces sold 450 pieces this year; Last year, 15 kilograms of durian with an average price of about 400 yuan per box sold directly to 800 yuan this year.
The epidemic affected the transportation time, and the freight cost generally increased by 10 times.
The reduction of production makes the price of fruit higher, and the increase of transportation cost adds a fire to the rising price.
According to Chen Ying’s estimation, in previous years, the freight for a car full of princess smiles was 9,000, but this year it has become 12,000. Affected by the local epidemic this year, the passage of trucks was not as smooth as in previous years, and the freight rate naturally rose.
Liu Ben (a pseudonym), a truck driver, took a load of bananas imported into Hangzhou fruit wholesale market. His batch of bananas was shipped from the port of Ningbo. Originally, this journey only took three or four hours, but now it takes three days.
Imported fruits need to go through customs inspection, disinfection and nucleic acid detection, and so on. Just here at the customs, it will take a day. When the goods arrived at the highway bayonet, Liu Ben had to hand over the driver’s license to the staff. "Because it is stipulated which highway intersection to get off from, you must return from which highway intersection."
When you get to the market, people and goods need a 24-hour nucleic acid report to enter the market. Liu Ben drove the car to Hangzhou Renhe Inspection Station and tested the bananas. Liu Ben himself went to the hospital to do nucleic acid, and when the report came out, another day passed.
Liu Ben calculated that it would take about 140 liters of oil to get from Ningbo to Hangzhou. This year, the oil price has risen, and he can only bear it himself. Together with the toll of 336, it costs 672 yuan to go back and forth. After deducting these costs, Liu Ben can only earn 500~600 yuan for one trip.
The epidemic situation makes it impossible for goods between markets to circulate and transfer at will. "Every batch of fruit we have now has a traceability code, which can only be sent straight from the place of origin and cannot be transferred. In the past, we would look at the price. For example, if the goods in Jiaxing market are cheaper, we will adjust from Jiaxing, and now it is not allowed. " Fei Ge (a pseudonym), the wholesaler owner of Hongshi Fruit Industry, said.
Feige is mainly engaged in the wholesale of fine fruits. Due to the difficulty of freight transportation in Shanghai, all the imported fruits were transferred to the docks in Guangzhou, which increased the transportation cost for the Hangzhou market.
The number of imported fruits has dropped sharply this year, mainly due to the international epidemic.
"I think many colleagues who are imported fruits are saying that the freight of imported fruits has generally increased by 10 times." Brother Fei said, "And in Southeast Asia and other countries where we mainly import fruits and fruits, almost all the automobile transportation routes are shut down, leaving only sea routes. The time for these fruits to stay on the cargo ship has increased, resulting in a decline in quality. "
Store rent, labor cost factor, local fruit listing price will be lowered.
The rise in wholesale prices makes the price tag of fruit shop stores change almost every day.
"Recently, many customers have complained to us that fruit has become more expensive." Xiao Wu, a clerk of Huaxia Fruit Industry, pointed out and smiled at the concubine in front of the store. This is litchi that just came in, and the price is 51.6 yuan a kilogram.
Most customers are still sensitive to price, so although the price of fruit has increased, the turnover has not increased, but has decreased.
Sun Liying, the boss of Huaxia Fruit Industry, told qianjiang evening news Hours that the turnover of his three stores was only about one-third of that of the same period last year, and the passenger flow was also much less.
Sun Liying has been a fruit store for 7 years, and now he has 3 stores in Hangzhou. The rent of the oldest No.1 shop has risen from 50,000 to 178,000 years, and the growth rate has increased by 5% year by year. The labor cost employed in the store accounts for 60% of the total expenditure. Sun Liying thinks that compared with these, the price of fruit has risen the slowest.
In 2020, Sun Liying’s store enjoyed the government rent reduction and exemption policy, exempting the rent for three months and halving the rent for three months, which made him through the most difficult period.
This year’s epidemic situation is complicated. Last month, two of his stores were shut down due to epidemic prevention and control, and some fruits were lost. "It’s good to live." Sun Liying said.
However, the epidemic has also increased the sales of storable fruits such as apples, pears and bananas, and the prices of these fruits are relatively stable.
Many people are concerned about when the price of fruit will come down.
Hong Lianggang said that when local fruit production comes up, the wholesale price of fruit will soon fall, and the price of retail stores will naturally be lowered.
Take watermelons as an example. In April, watermelons were scarce, and the wholesale price once rose to 18 yuan a kilogram. However, with the maturity of local sweet potatoes in May, the price of watermelons will drop to 4 yuan a kilogram.
"I don’t know, one price a day." A stall owner who sold watermelons for 7 years in Hangzhou Fruit Wholesale Market said.
Today’s People’s Daily published an article "Adding More Seaside Space for Citizens and Tourists" in the column "Practice of Ludao Butterfly in Xiamen", paying attention to the continuous beach protection and restoration in Xiamen, Fujian.
The article said that in the 1980s, due to natural and human factors, the beaches in Xiamen were damaged to varying degrees. The common method of early coastal protection is to build hard revetment with riprap and reinforced concrete. Xiamen, on the other hand, follows the principle of "beach is suitable" to restore beaches, enhance coastal protection capacity and carry out systematic protection and restoration of beaches.
Since 2007, Xiamen has successively completed the protection and restoration of many beaches such as Guanyin Mountain, Convention and Exhibition Center and Gulangyu Island, with a cumulative restoration area of 1.65 million square meters. In the process of protection and restoration, Xiamen insists on leaving the most beautiful coastline to the people. The total beach area of the city is 2.4 million square meters, which adds more sea-friendly space for citizens and tourists. Xiamen organically combines sports, culture, tourism and leisure facilities, and organizes beach football matches, beach culture festivals and other activities. The once dirty beach has become a scenic beach and an activity area for cultural and sports events.
In recent years, Xiamen has continuously strengthened cooperation with scientific research institutes in beach protection and restoration, increased investment in scientific research and development, and carried out basic and applied scientific research on beach conservation. Together with the Third Institute of Oceanography of the Ministry of Natural Resources and other units, a number of industry standards have been compiled and approved by the Ministry of Natural Resources, which has become an important support for scientific and standardized beach maintenance and restoration projects. Related technologies have been gradually extended to Guangdong, Hainan and other provinces, and have also been applied to coastal protection projects in countries such as Thailand and Sri Lanka where the Belt and Road Initiative is jointly built.
