According to the analysis of the Decision Service Center of the China Meteorological Administration, the temperature in the second half of February is close to normal or high, which is generally conducive to the production of agriculture and animal husbandry. In late February, temperatures in most parts of the northwestern region, north China, and northeastern China will be 1 to 3 °C higher than normal. The temperature in most other parts of China is close to normal; it is generally conducive to agricultural and livestock production. Some areas may be adversely affected by windy weather.

The specific analysis is as follows:

From 21 to 23, there will be weak cold air affecting northern Xinjiang, central and eastern Inner Mongolia, and northeastern China, and the temperature will drop by 3-6 °C. The northeastern part of Inner Mongolia and the northern part of Northeast China will cool down by 8-10 °C, accompanied by 4~. Grade 6 wind; cooling windy weather is not conducive to facility agriculture and animal husbandry production, and it is easy to damage greenhouse greenhouses, livestock pens and livestock.

From 24 to 26, affected by moderate-intensity cold air, the central and eastern regions of China will cool down by 4-8 °C, with the northern and northern parts of North China cooling down by 10-12 °C; the middle and lower reaches of the Yangtze River and the north of them are 4-6. North wind. The cooling may cause the winter wheat that has just returned to the south of Huanghuai and the northern part of the Yangtze River to suffer from freezing damage. It is also not conducive to irrigation of winter wheat in the drought-affected areas such as North China and Huanghuai. In addition, windy weather is also detrimental to facility agriculture and animal husbandry production.
Winter wheat in North China and Huanghuai will continue or develop drought conditions in the dry areas. Before the 24th, there was no obvious precipitation in North China and Huanghuai, and the impact of drought will increase. On the 24th to 26th, some areas in the northwestern part of the northwest, the western part of Huanghuai, and the western part of North China will have small to medium snow (rain), which is conducive to soil growth. Oh, but it is difficult to effectively alleviate the drought.

The rainy weather in the south is not conducive to the robust growth of crops. In late February, there were many rainy weather in the eastern part of the southwestern region, Jiangnan, and southern China. The precipitation was 5 to 25 mm, of which 30 to 50 mm was localized in Jiangnan and northern China. The continuous rainy weather is not conducive to the robust growth of winter wheat, rapeseed, vegetables and fruit trees. Soil moisture in Jiangnan and northern China will be aggravated, which is not conducive to crop root growth.

For the weather conditions, make the following agricultural production recommendations:

First, the winter wheat in the north will gradually enter the greening period. It is necessary to take measures such as cultivating loose soil and fertilizing in time to increase the temperature and ensure the winter wheat to grow normally. The dry areas should pay close attention to the weather changes. The average temperature in the unirrigated areas should be 3 Irrigation is carried out in the warm and warm afternoon above °C to ensure timely infiltration of water and no clear water on the surface of the farmland.

Second, the southwestern region, the middle and lower reaches of the Yangtze River and the south of the Yangtze River should adopt measures such as cultivating and topdressing to promote the growth of winter wheat and rapeseed winter crops; soil over-wet areas should grasp the precipitation gap, clear the ditch in time, and prevent wet stains. Harm occurs; in addition, it is necessary to strengthen the monitoring and prevention of pests and diseases.

Third, the northern region should also do a good job of wind protection and reinforcement of facility agriculture, livestock pens, etc., as well as livestock cold protection and forage supply work, to prevent the adverse effects of windy weather.
