The National Meteorological Center predicts that the cold air activities affecting China will be more frequent in the next 10 days. The temperature in most parts of the country is 1~2°C lower than normal. The rain and snow in most parts of the north are less, and there is no precipitation in North China and Huanghuai. Low temperature and drought pose a threat to the safe wintering of winter wheat that has not been over-watered in Hebei, most of Henan, and northwestern Anhui.

From 14 to 15 days, a medium-intensity cold air will affect the central and eastern regions of China. In the north and the Jianghuai, Jiangnan, Guizhou, and South China, there will be about 5 northerly winds, and the temperature will drop by 3 to 7 °C. Strong winds and winds are likely to cause damage to greenhouses, livestock and poultry houses, and easily lead to weakened young animals.

Before the 15th, the range of freezing rain in the south was significantly reduced. From 16 to 19, the freezing process of low temperature rain and snow in the south will be strengthened again. In the south, there will be a rain and snow weather from west to east. There will be small to moderate rain in the east of the southwest, and the middle and lower reaches of the Yangtze River. There are small to medium snow, local heavy snow, and there are freezing rains in Guizhou, western Hunan, and northeastern Guangxi. The low temperature freezing rain and snow weather is unfavorable for the growth of winter wheat tillers, rapeseed buds and open field vegetables, fruit trees, economic forests, etc., which may cause some winter wheat, rapeseed leaves and southern cash crops to suffer from freezing damage. Rain and snow will also cause soil over-humidity in parts of the middle and lower reaches of the Yangtze River, which is not conducive to the normal growth of wintering crops.

Suggestions for this:

1. Do a good job in wind and cold protection of facility agriculture and animal husbandry. Greenhouse greenhouses should adopt measures such as reinforced scaffolding, thickening cover and artificial heating to keep warm and increase temperature to prevent the occurrence of freezing damage; the pastoral area should prepare enough livestock feed, and do a good job of reinforcement and cold protection.

2. In the southern areas where conditions are available, measures such as applying straw ash, covering straw or film can be used to increase soil temperature and prevent freezing disasters; in over-wet areas, it is necessary to take 12-10 days of rain and snow to grasp the clearing ditch and reduce the soil moisture of farmland. To avoid the occurrence of wet stains.

3. In the wheat field with the lowest temperature above 0 °C in the north, timely irrigation and enhanced post-irrigation conservation work; the wheat field that has entered the wintering period, adopts organic fertilizer and cover to protect and freeze, and ensure the winter wheat is safely wintered.
