In the next few days, there will be more precipitation processes in Jiangnan and South China, and there will be strong convective weather in the local area. The average temperature in most parts of winter wheat area is 1-2°C higher than normal. The precipitation in most parts of Northeast China has an increasing trend compared with the previous period. Field work should be done to clear the ditch drainage, adjust the soil moisture, and pay close attention to planting, and strengthen field management.
According to the mid-term forecast of the Central Meteorological Observatory, in the next 10 days (April 18-27), some areas in the south of the Yangtze River, South China, and Southwest China have more rainy weather. The cumulative rainfall in most areas is generally 30-80 mm, including southern Jiangnan. Some areas in South China and other places have 150-200 mm; rainfall in most parts of the Yangtze River and Huaihe River is 15-25 mm; rainfall in the eastern part of the northwestern region, North China, Huanghuai, Northeast China, etc. is generally 1-10 mm, including Huanghuai, Northeast, etc. The local area of ​​the land is 20-30 mm; the precipitation on the Qinghai-Tibet Plateau and northern Xinjiang is 1-5 mm.
It is also expected that in the next 10 days, the cold air forces affecting China will not be strong. The temperature in the northwest and north-north of North China and northeast China will be 1-3°C higher than normal. The temperature in other parts of China is basically close to the same period of the previous year.
The Yangtze River Basin should use the gap of the precipitation to clear the ditch, reduce the soil moisture in the field, and ensure that the dry land crops such as cotton are planted at the right time. In southern Sichuan and northern Yunnan, it is necessary to seize the favorable opportunity of precipitation, do a good job of water storage and conservation, and timely replant or replant dryland crops.
The northeast region will enter the peak period of spring sowing. It is suggested that the weather should be grasped and the progress of rice planting and breeding should be accelerated. The already-seeded areas should be protected from wind and heat insulation in the nursery greenhouses; the drought-stricken areas in the west can be planted with rain or “waterâ€. Such measures will promptly sow spring corn; the eastern region will seize the time to plow the ploughing, increase the ground temperature, and create suitable conditions for corn planting.
