Winter wheat turns green one after another, the south needs to prevent continuous overcast and rain.

National agrometeorological information shows that in the coming week, the temperature in most parts of China is on the high side, the south will be cloudy and rainy, and the soil in Jianghuai, Jianghan and some parts of Jiangnan will continue to be too wet, which is not conducive to the growth of winter wheat, rape, local vegetables and economic forest fruits.

At present, winter wheat in most areas of Northwest China, North China and Huang-Huai is in the overwintering period, while in southern Xinjiang, the southeast of Northwest China, North China and parts of Huang-Huai region, winter wheat has entered the green stage. Most of the winter wheat in Jianghan and Huaihe River was in the tillering stage, most of the winter wheat in the south and southwest of Jianghan entered the jointing stage, and some parts of Yunnan entered the heading to flowering stage. In the coastal areas of Fujian and Guangdong, early rice is in the stage of sowing and emergence, while Hainan is in the stage from three leaves to tillering.

It is estimated that from the 23rd to March 1st, the temperature in most parts of the north will be about 1 ℃ higher than that in the same period of the normal year; from the 25th to 28th, there will be light to moderate snow or sleet in the eastern part of Northwest China, the western and southern parts of North China, and Huang-Huai, which will further supplement the soil moisture and be conducive to the safe overwintering and normal green growth of wheat. However, from 22nd to 23rd, under the influence of cold air, most of the central and eastern parts of Inner Mongolia and Northeast China cooled by 610 ℃, and the temperature of some areas such as Northeast Inner Mongolia and the central part of Northeast China dropped by 1214 ℃, which was not conducive to facility agriculture and animal husbandry production. Meteorological experts suggest that the northeast and Inner Mongolia should do a good job in wind protection and cold protection of facilities, sheds and livestock sheds, so as to prevent damage to sheds and freezing of crops and young animals. Northern winter wheat has entered the green growth period one after another, all localities should pay close attention to the weather forecast and soil moisture, do a good job in wheat field classification management, according to soil moisture and seedling conditions, timely irrigate turning green water and topdressing returning green fertilizer, so as to promote the steady growth of winter wheat after turning green; the wheat field with prosperous seedlings should be suppressed timely and appropriately to improve the rate of tillers and spikes.

In the coming week, although the temperature in most parts of the south is on the high side, there will be a lot of overcast and rainy weather, of which the precipitation in Jianghuai, Jianghan, Jiangnan, South China, Guizhou and Chongqing will be more than 90 mm, and the soil will continue to be too wet in some areas. it has adverse effects on the growth of winter wheat, rape, local vegetables and economic forest fruits. In addition, around the 27th, rain changed to sleet in Jianghuai and other places, and some local crops may suffer from snow disasters or frost damage. Meteorological experts suggest that winter wheat and rape producing areas in the south should continue to do a good job in field management, and that in wet soil areas, attention should be paid to timely clearing ditches and regulating soil moisture to avoid the occurrence of wet waterlogging; winter wheat and rape in southwest China have entered a stage of exuberant growth, and all localities should apply fertilizer in a timely manner according to the growth of crops to ensure nutrient supply. Southern China has entered a suitable sowing period for early rice. All localities should take advantage of the favorable weather of high temperature in the near future to speed up the sowing progress and ensure timely sowing and seedling raising of early rice.
