Will there be dry and hot wind in the winter wheat area of Huanghuai in North China in the next three days?

May 16 According to the website of the Central Meteorological Observatory, it is predicted that there will be dry and hot wind weather in the winter wheat area of Huanghuai, North China from June 17 to June 19, which is unfavorable for winter wheat filling and may lead to a decrease in the filling rate and grain weight of winter wheat. At present, winter wheat in North China and Huanghuai is in the critical stage of yield formation of flowering, pollination and filling. /kloc-the monitoring of soil relative humidity of 30 cm in May/May showed that the soil in eastern North China and western Huanghuai was slightly deficient, while the soil in central Hebei and western Henan was moderately deficient. 10 ~ 13, dry hot wind weather occurred in Henan for 1 ~ 3 days, which had adverse effects on winter wheat filling.

It is estimated that in the coming week, the average temperature in most winter wheat areas in the north will be higher than normal, and that in North China and other places will be 4 ~ 5℃ higher. From 17 to 19, the weather in Beijing, Tianjin, Hebei, Henan, Shanxi and northern Shandong continued to be sunny and hot. The highest temperature is generally above 32℃, the relative humidity of the air is relatively low, and the wind force in the afternoon is generally greater than 3 m/s. Coupled with the deviation of soil moisture in some areas, there will be "dry and hot wind" weather in winter wheat areas. Among them, from18 to19, the highest temperature in parts of central and southern Hebei and northern Henan can reach about 37℃, and there will be moderate to severe "dry hot wind" weather, which is not good for winter wheat filling, leading to the decline of winter wheat filling rate and grain weight.

The winter wheat areas in North China and Huanghuai need to manage water and fertilizer in time, and do a good job of "one spraying and three prevention" to increase the anti-aging ability of wheat; Irrigate in time in areas where soil moisture is deviated, improve the temperature and humidity conditions in the field, and avoid or reduce the harm of dry hot wind.
