It is expected that the cold air activities affecting China will be more frequent in the next 10 days. Except for the temperature in the northern part of Heilongjiang and parts of Tibet, which is close to normal or slightly higher than normal, the temperature in most other parts of the country is 1~2 Â°C lower than normal; 26~29 On the day, affected by a strong cold air, China will have a large-scale process of rain and snow and windy weather. In the next 10 days, there will be more rain and snow in the eastern part of the southwestern region, and there will be a significant precipitation process in the south of the south of the Yangtze River and the southern part of China. The precipitation in the above areas is generally 5 to 15 mm. During the day of the 22nd to 26th, the meteorological arid areas such as North China and Huanghuai are still There is no obvious precipitation; around the 27th, there will be 1 to 3 mm of snowfall in some meteorological arid regions such as southern North China and western Huanghuai. Gale winds, rain and snow weather are unfavorable for the growth of winter wheat, rapeseed and open vegetables, potatoes, tobacco, fruit trees, economic forests, etc., and will also affect facility agriculture and animal husbandry production. Excessive soil moisture in farmland in the southeastern part of the southwest, south of the Yangtze River and parts of southern China will continue. The farmland in the southern part of North China and the western part of Huanghuai is expected to increase in the late second half of the year.
1. The northern winter wheat area continues to dry and cold weather, and there is no snow cover in the wheat fields of North China, Huanghuai and other places, which is easy to cause the situation of drought and freezing. For the plots that have been over-wintered and have better seedlings, they are managed according to conventional methods. For plots with irrigated conditions but not over-watered, use a sunny day with a daily average temperature of 3 Â°C or above. The water is poured finely, and the fertilizer is properly topdressed, and the plots are preserved; the plots without hydration conditions are repressed and slashed.
2. The southern part of the country should continue to strengthen the work of wintering crops, facility agriculture, and aquatic products. In areas where the soil is too wet, it is necessary to grasp the clear ditch and reduce the soil moisture of the farmland. At the same time, it is necessary to apply organic fertilizer to the crops with long-term deviations in order to increase the ground temperature and promote the steady growth of crops.
