Most of the drought in the winter wheat area has been significantly eased
On February 9-10, 12-13, there were two precipitation processes in the northern winter wheat arid area. The cumulative precipitation was generally 2-8 mm, including 10~ in southeastern Henan, northern Anhui, and northern Jiangsu. 15 mm. Since February 18, the temperature in the winter wheat area has rebounded remarkably. The soil of 10-20 cm in the middle and south of the winter wheat area has been frozen, and most of the wheat areas are suitable for irrigation. The progress of drought-resistant watering is accelerated, and the soil moisture is obviously improved compared with February 9. . According to the soil moisture monitoring and analysis on February 22, the soil surface defect area is concentrated in the central and western Henan, north central Shandong, northern Anhui and other places; the lack of sputum is significantly reduced, mostly mild defects.
At the end of the month, there will be significant precipitation in the northern winter wheat and arid regions.
It is estimated that from the 25th to the 28th, the precipitation in the eastern part of the northwestern region, north China, and Huanghuai will be generally 5 to 15 millimeters. The cumulative precipitation in the southwestern part of Shaanxi, southwestern Shanxi, south central Henan, central and northern Jiangsu, etc. is 15-30 mm. The drought in most dry areas will be significantly eased, the scope of drought will be reduced, and the degree will be reduced. The drought in northern Anhui will be lifted; compared with the two precipitation processes on February 9-10 and 12-13, the precipitation process has Long duration, wide coverage, and large amount of process precipitation. However, the precipitation in the central and eastern parts of North China and northern Shandong is less than 5 mm, and the drought in southern Hebei and northern Shandong continues.
Agricultural production advice:
It is expected that there will be strong winds and cool weather in most parts of the north on the 24th to 28th. The cooling range is generally 4 to 6 °C, in some areas 8 to 10 °C, and the wind is generally 4 to 6.
The northern winter wheat and arid areas should pay close attention to the weather changes and carry out scientific irrigation according to the seedlings and sensation. Among them, the southern part of Hebei Province and the dry area of ​​northern Shandong still have to pick up the temperature, and irrigate in the warm and warm afternoon; and combine fertilization according to the condition of seedlings and fertility; while paying close attention to temperature changes, if the average daily temperature falls below 3 °C, Stop irrigation and ensure that there is no clear water overnight to prevent freezing damage to wheat. In other dry areas, due to significant precipitation from 25 to 28 days, areas with good moisture and good seedling conditions may be appropriately postponed to return to Qingshui.
