According to the Meteorological Bureau, in the second half of February, the temperature in most parts of the northwestern part of China, North China, Northeast China and other places will be 1-3 °C higher than normal. The temperature in most other parts of China is close to normal, and the overall climatic conditions are favorable to farmers. Animal husbandry production.
However, some areas may be adversely affected by windy and cool weather. It is expected that 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, including northeastern Inner Mongolia and northeastern part of China. Local cooling is 8-10 °C, accompanied by 4-6 winds; cooling windy weather is not conducive to facility agriculture and animal husbandry production, easy to damage greenhouse greenhouses, livestock pens and livestock.
At the same time, from 24 to 26, due to the influence of medium-intensity cold air, the central and eastern regions of China will cool down by 4-8 °C, in which the northern part of North China and the northeast are cooled by 10~12 °C; the middle and lower reaches of the Yangtze River and the north of the Yangtze River have grades 4-6. Northerly 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, and it is not conducive to the 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 livestock production.
Northern dry and rainy north adverse crop growth
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. From 24 to 26, some areas in the northwestern part of the western region, 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.
In the second half of February, the farmland warmed up and protected the ditch.
Experts suggest that 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 normal growth of winter wheat. The dry areas should pay close attention to the weather changes. The average temperature of the unirrigated areas should be Irrigation is carried out in the warm and cold afternoon above 3 °C to ensure timely infiltration of water and no clear water on the surface of the farmland.
In order to cope with the windy and windy weather, the northern region should also do wind-proof reinforcement of facility agriculture, livestock pens, etc., as well as livestock cold-proof and warmth and forage supply work, to prevent the adverse effects of windy weather.
In the southwestern region, the middle and lower reaches of the Yangtze River and the south of the Yangtze River, measures such as cultivating and topdressing should be adopted to promote the growth of winter wheat, rapeseed and other winter crops; in the soil over-wet areas, the precipitation gap should be grasped, and the ditch should be cleared in time to prevent wet waterlogging. Occurs; in addition, it is necessary to strengthen the monitoring and prevention of pests and diseases.
