Three characteristics of China’s water cycle: increasing precipitation, warming and humidifying in the west of southern waterlogging and northern drought

  Cctv newsOn March 27th, the joint prevention and control mechanism of the State Council held a press conference to introduce the work of preventing meteorological disasters, ensuring the resumption of work and preparing for spring ploughing. The heads of relevant departments of China Meteorological Bureau and the Ministry of Agriculture and Rural Affairs answered questions from the media.

  Reporter: This year’s World Meteorological Day has just passed. I noticed that this year’s theme is "Climate and Water". What impact will climate change have on China’s water resources? Will it lead to an increase in the frequency of droughts and floods across the country?

  Zhou Bing, Chief Expert of Climate Service of National Climate Center of China Meteorological Bureau.Every year on March 23rd, World Meteorological Day, the World Meteorological Organization and the international meteorological community will hold activities to publicize popular science around a related theme. From 1961 to 2019, seven of the 59 World Meteorological Days have been related to water. This year’s theme is "Climate and Water", which shows the importance of water in meteorological work.

  Climate change affects the global water cycle and the distribution of water resources. According to the climate statement of the World Meteorological Organization, the global average temperature in 2019 was 1.1℃ higher than the average from 1850 to 1900, which was the second hottest year on record after 2016, consistent with the global warming trend. Since 1951, the annual average surface temperature in China has increased by 0.24℃ every ten years. Climate change is changing the distribution of water resources, the characteristics of precipitation and the change of precipitation intensity, which will change the regional flood situation, and even make the dry places more and more dry and the wet places more and more wet. In recent 50 years, the average number of rainy days in China has generally shown a downward trend, mainly because the number of light rain days has decreased significantly, by 13%, while the number of heavy rain days has increased by 10% instead of decreasing. The decrease of light rain days means that the risk of drought increases, while the increase of heavy rain days means that the frequency of short-term heavy precipitation events increases and the risks such as urban waterlogging increase.

  China water cycle has three characteristics. First, in the 21st century, the precipitation in China is increasing, and the water cycle is intensifying. Second, there is a situation of waterlogging in the south and drought in the north, and the shortage of water resources in the north is intensified. Third, most areas in the west are getting warmer and wetter, showing the characteristics of warming and wetting. Therefore, we should pay more attention to the frequent occurrence of extreme weather and climate events and the changing characteristics of drought and flood distribution in China under the background of global warming, and effectively improve our ability to cope with climate change.

Minority fruit becomes "noble": Myrica rubra 108 yuan/kg kiwifruit 13.9 yuan/piece.

  Eating river shrimp is just the time, and the price is cheaper than fruit! After qianjiang evening news reported this report yesterday, some friends expressed dissatisfaction: How is this possible?

  This question is not for shrimps, but for fruits. Can’t fruits be eaten? These two days, qianjiang evening news reporters visited a number of fruit shops and told you what the real situation was like.

  The same litchi, the price is two days.

  Yunnan Tanmei (Yangmei) is 108 yuan a catty.

  In the "Baiguoyuan" fruit shop on the edge of Jindu Hua Ting, Zhaohui Road, Hangzhou, the reporter saw that the nominal A-class nephew smiled lychee, with a retail price of 23.9 yuan a catty and a membership price of 19.9 yuan a catty; Domestic cherries (large) 99 yuan a catty; Grade B cherry (middle) 51.9 yuan a catty … …

  Also, small kiwifruit imported from New Zealand, 6.9 yuan/a; The big one is 13.9 yuan/piece. That’s right, 13.9 yuan each!

  "In the past, when the domestic kiwifruit in 3 yuan was one kilo more, New Zealand kiwifruit sold in 3 yuan. Now New Zealand kiwifruit is so expensive? How much does this big kiwi weigh? " At the reporter’s request, the salesperson took a large kiwi fruit and put it on the electronic scale: 150 grams, more than 3 kiwis per catty, equivalent to one catty of 46 yuan.

  In the nearby Ye Brothers Fruit Fruit Shop, Yunnan charcoal plum (Myrica rubra) is 108 yuan a catty; A basket of lychees is estimated to be about 3 kg, and the price is 198 yuan. "This is a grade litchi, 68 yuan a kilo. B-class litchi (nominally Hainan Xiaozixiao Special Grade) sells 27.8 yuan a catty, and the membership price is 25.8 yuan a catty. " The salesperson said.

  Fruit, is it really unbearable?

  Fortunately, there are fruits that can be eaten by biting your teeth. The reporter saw that in the Ye brothers fruit shop, the apples with a diameter of 80 (mm) were sold in 9.9 yuan at a membership price; In the Baiguoyuan store, the member price of Taiwan Province pineapple is 13.5 yuan a catty, and there are several yuan a catty of bananas … …

  A fruit shop located at the Jianguo intersection of Stadium Road, besides a catty of small cherries in 68 yuan, there are also a catty of apples in 8.8 yuan. Posters of "Oriental Honey 8.8 yuan/Jin" and "Crystal Sugar Kylin Melon 3.99 Yuan/Jin" were posted on the walls of the store, which were very eye-catching.

  Not far from the door of a specialty store next door, a lot of whole boxes of apples were stacked. Shopkeeper said that these apples are all "rock candy hearts" in Xinjiang, weighing 10 Jin per box and about a dozen in 88 yuan. "Now the apples are all frozen, but they are still very sweet!" The boss said.

  Why is fruit expensive now?

  The off-season of fruit and the disastrous weather caused a reduction in production.

  "It is true that fruit is expensive at present." Lu Chaofa, deputy general manager of Hangzhou Fruit Wholesale Market, has his own analysis — — There are two main reasons. First, it is the off-season of fruits, and summer fruits have not been listed on a large scale, so the market supply is a bit green and yellow. At present, the main products on the market are domestic small varieties of fruits, and the quantity is not large; Second, the impact of disastrous weather caused fruit production to decrease.

  Take litchi as an example. Last year was a big year, but this year is a small year. The output is small, and the price will definitely be higher. The purchase price of litchi in Hainan is estimated to increase by 10% to 15% compared with the same period last year. At present, the wholesale price in the market is around one catty in 9 yuan. However, from late May to June, with the listing of litchi in Guangdong, Guangxi, Fujian and other places, the price will gradually fall back. In other words, if you want to try something fresh now, the price will definitely be high; If you want to eat cheaper litchi, you can wait.

  Lu Chaofa also reminded that the taste of litchi is not as good as in previous years because of the rainy weather and less light this year.

  Since the end of last year, popular fruits such as apples and pears have also been more expensive than in previous years. "Last year, due to the large-scale spring cold in the north, the output of apples dropped sharply, and the quality was not as good as in previous years. In places like Gansu and Shaanxi in the northwest, the yield of good apples is reduced by 40% to 50% or more, and that of Shandong apples is reduced by about 30%. As a result, the purchase price has risen sharply. " Lu Chaofa said.

  The price of bananas began to increase last year, mainly because of the large-scale yellow leaf disease in some producing areas the year before last. In order to control the disease, production was reduced. Last year, the wholesale price of bananas was about a kilo higher than that of 1 yuan. The market this year is similar to last year.

  Not all fruits are more expensive than in previous years. This year is a big year for pineapples. In April, the average wholesale price of Hangzhou fruit wholesale market was 5.7 yuan/kg, compared with 6.5 yuan/kg in the same period last year. The price of pineapple is similar to that of last year. At present, the market supply of pineapple and pineapple is coming to an end.

  Lu Chaofa said that at present, imported fruits have also entered the off-season. Among kiwifruit imported from New Zealand, yellow kiwifruit is twice as expensive as green kiwifruit. "Green-hearted kiwifruit in New Zealand, the normal wholesale price in the peak season is about one box (36 pieces) in 100 yuan, and now a box from 150 yuan to 170 yuan."

  Since the end of this month, Zhejiang local summer fruits such as peaches and bayberry have been listed one after another, and the supply of fruits is expected to improve. Lu Chaofa said that this year is a small year for Yangmei in Zhejiang, and the price will be slightly more expensive than last year. But at least, you don’t have to worry about not being able to afford it. (Reporter Wang Yanping Gao Jiachen Wen/photo)

Moon viewing is a traditional culture of Mid-Autumn Festival, but at the same time, it is now integrated into our economic life. In the past two years, not only the Mid-Autumn Festival, but also many people take the moon viewing as their tourism theme. For example, outdoor camping has the dual functions of tourism accommodation and moon viewing. Traditional culture integrates fashion consumption, and this Mid-Autumn Festival holiday, Starry B&B has also become a new choice for many people to travel.

Discussing "winter" in winter, kindergarten teachers conducted a teaching activity appraisal.

Chao News Client Correspondent Feng Jiadan
In order to further optimize the construction of teachers and improve the quality of kindergarten education and teaching, Xiangyang Kindergarten Education Group in Qiantang District of Hangzhou recently launched a collective teaching activity appraisal activity under the theme of complete children.
This appraisal activity revolves around the theme of "winter" under the complete children’s curriculum. Sixteen teachers in Xiangyang and Xiangshang parks carefully prepared lessons in the early stage, devoted themselves to studying the teaching materials, and actively tried teaching and prepared well in combination with the age characteristics of the children in the class.
Seven teachers in the small class chose the teaching activities under the theme of "Winter is Coming". Combining with the age characteristics of children, the teachers designed interesting and operational activities with different ideas, different entry points and key points, so that children could experience the fun of playing, doing, talking and playing games in winter.
The theme of "I exercise, I am healthy" belongs to the dimension of "children and nature". Seven teachers in the middle class choose to teach in the fields of science, language and art, and explore various ways to keep out the cold in life with children by operating and experiencing, so as to actively cope with the brave journey in winter.
Under the theme of "The Secret of Winter", two teachers in the big class chose the social activity "An Unforgettable Year" and the language activity "The Chinese Zodiac", and used different strategies and methods to let the children understand and experience the rich emotions and beautiful meanings contained in winter life in the immersive participation and experience, thus generating a sense of identity and belonging to Chinese traditional culture.
After the appraisal, the judges and the teachers on the spot had a heated discussion on each teacher’s activity performance, focusing on the achievement of activity objectives, activity organization and teacher-child interaction. Everyone put forward their own ideas on the highlights of each class, the teaching characteristics of each teacher and the places to be improved.
Every teaching appraisal is an effective study, an improvement of ability and a growing experience. This "evaluation activity of collective teaching activities under the theme of complete children" has not only built a stage for teachers to tap their potential, show their elegance and surpass themselves, but also created a platform for other teachers to observe and learn from others, learn from others and discuss and communicate. I believe that through effective grinding again and again, "high quality and high efficiency" classroom teaching will be further implemented in normal teaching, laying a solid foundation for promoting the high-quality development of education.

I heard that there are pesticide residues in tea? Tea lovers should not panic.

  It’s spring tea season again. The problem of pesticide residues in tea can be said to have never stopped, and there will be some very eye-catching posts from time to time. Let’s talk about whether the problem of pesticide residues in tea is serious today. Is drinking tea really equal to drinking pesticides?

  Why do you want to use pesticides in tea?

  Tea is widely loved because of its natural and healthy properties, and even a necessary drink for many people every day. Tea drinkers naturally hope that the tea they drink is green and pollution-free, without pesticides or other harmful substances, but this is unrealistic.

  Tea trees usually grow in a warm and humid environment, which is prone to pests and diseases, and the use of pesticides is inevitable in the process of large-scale planting. According to statistics, there are dozens of pesticides used on tea trees or tea leaves at present, mainly pesticides and herbicides.

  What pesticides are mainly used in tea?

  China began to use pesticides in tea production in the early 1950s, with a history of more than 60 years. In the first 20 years, DDT and HCH were mainly used in tea, so the level of pesticide residues in tea at that stage was the highest.

  Later, people gradually realized that these pesticides would remain in the environment for a long time and would not be degraded, so that they could be found in almost every corner of the earth, which brought lasting pain to our living environment, so countries banned their production and use one after another.

  With the development of society, more and more pesticides with high residue or high toxicity have been eliminated and replaced by some pesticides with high efficiency and low toxicity. Tea is no exception. The Food Safety Law of People’s Republic of China (PRC) stipulates that it is forbidden to use highly toxic and highly toxic pesticides in crops such as vegetables, fruits, tea and Chinese herbal medicines.

  Is the pesticide residue on tea harmful?

  Since pesticides are applied to tea, there will inevitably be some residues, but there are two different things: pesticide residues and pesticide residues exceeding the standard.

  All the pesticides allowed to be used in tea by the state are low toxic pesticides, and the Maximum Pesticide Residue Limit in Food of National Standard for Food Safety (GB2763-2016) stipulates the limit requirements of 48 pesticides in tea. These limit values are obtained according to scientific risk assessment. As long as the pesticide residue in tea does not exceed the standard, it is safe for consumers.

  Moreover, most of the fat-soluble pesticides used in tea are pyrethroids, and the amount that can be leached into tea is very limited in the process of making tea.

  In short, having pesticide residues does not mean harm. The human body is not so "incompetent", it can metabolize a small amount of pesticides or other harmful substances that enter the body, or it is a cliche: it is hooliganism to talk about toxicity without dosage! Not only tea, but also pesticide residues in other agricultural products.

  How to reduce pesticide residues in tea?

  Although the pesticide residues in qualified tea that meet the standards are safe for consumers’ health, everyone definitely wants to consume as little pesticides as possible. In order to reduce pesticide residues in tea, we can start from the following aspects:

  1. Tea farmers use pesticide varieties with low residue and easy degradation in accordance with state regulations, and strictly control the usage.

  2. Ensure the safe interval of tea picking. As a kind of plant, tea itself has a certain metabolic ability to pesticides. Picking tea after spraying pesticides for a period of time (ranging from 7 to 15 days) can significantly reduce the residual pesticides in tea.

  3. Using ecological control measures to control pests and reduce the use of pesticides will also greatly reduce pesticide residues in tea.

  Consumers should buy tea produced by regular manufacturers.
