It is expected that in the next 10 days, the cold air activities affecting China will be more frequent. Except for the average temperature in the Qinghai-Tibet Plateau and western Yunnan, which is 1~3°C higher than normal, the rest of the country's temperature is lower than normal; 14-15 days, one The medium-strength cold air affects China, and there will be about 5 northerly winds in the middle and lower reaches of the Yangtze River and its north, and the temperature in the central and eastern regions will drop by 3-7 °C.

Suggest:
1. During the winter season, the weather is extremely cold. In the northern winter wheat area, all kinds of wheat fields should be treated with organic fertilizer to increase temperature and protect the wheat, and the wheat seedlings should be protected from freezing damage. At the same time, the greenhouses should be strengthened and warmed.
2. All parts of the south should continue to strengthen the cold-proof and anti-freezing work of winter crops, greenhouse vegetables, flowers, fruit trees, livestock, aquatic products, etc., to prevent the damage caused by low-temperature rain and snow, and the areas where the soil is too wet should pay attention to clearing the ditch in time to prevent The roots of the crop are stained.
