April rain, northwest worry about Zhongnanli, greenhouse protection winter Maixi

According to the monitoring and forecast of the China Meteorological Administration, from April 4 to 8, it is expected that most of China will be affected by a cold air, and most areas will have rain and snow to cool down the weather.

 

It is estimated that from 4th to 6th, the temperature in Xinjiang, Northwest China, Inner Mongolia and other places will reach 6-8 °C, and the local area can reach 10-12 °C. Most of Xinjiang, Inner Mongolia, Gansu Hexi Corridor and other places have 5 to 7 winds, and the Xinjiang Shankou region can reach 11 to 12 winds. Some areas of Xinjiang's Nanjiang Basin, western Gansu, and central and western Inner Mongolia have sand or floating dust, and local dust storms. There are small to medium snow or sleet in the northern part of Xinjiang, the central and eastern parts of the northwestern part, and the central and eastern parts of Inner Mongolia. Among them, the local area along the Tianshan area in Xinjiang has large blizzards.

From the evening of the 5th to the 7th, there will be small to moderate rains in the western and southern parts of the northern winter wheat area. The precipitation is 1 to 5 mm. The precipitation in the central and southern Anhui and Jiangsu is 8 to 15 mm, which is beneficial to the growth of winter wheat. During the period, the temperature drop in the northern winter wheat area is about 2 to 4 °C, and the local temperature is about 6 °C. The lowest temperature in Huanghuai is 4-8 °C. The average temperature is close to normal, and it will not affect the growth of winter wheat.

From the 6th to the 8th, Jianghan, Jianghuai and Jiangnan in the north of the early rice planting will have small to moderate rain (precipitation 8 to 15 mm) and heavy rain (25 to 40 mm) in some areas. During the period, the minimum temperature in the above-mentioned areas was 10 to 14 °C, and the temperature was generally close to the same period of the year, which had little effect on the early rice planting.

The adverse effects of wind, cooling, dust and other weather on facility agriculture are well protected. Precipitation further supplements the soil moisture in the winter wheat area in the north, which is beneficial to the winter wheat jointing and spring wheat sowing and emergence. However, the windy and dusty weather in Hexi, Gansu, central and western Inner Mongolia, Ningxia and other places is not good for facility agricultural production, and measures such as reinforcement should be taken to prevent it.
