Affected by natural precipitation and artificial snow, from the evening of the 12th to the afternoon of the 13th, snowfall occurred in most parts of Hebei Province. The average precipitation in the province is 0.8 mm, of which the maximum precipitation in Yucheng is 3.8 mm. More snowfall areas mainly occur in the central part of Zhangjiakou, northern Baoding, northern Langfang and eastern parts of Zhangzhou, Hengshui, Xingtai and Chongqing. The snowfall was the second large-scale snowfall in Hebei Province since the winter.
The snowfall is more beneficial to increase soil moisture, reduce drought and reduce forest fire risk rating. However, due to the small amount of precipitation, it is not enough to alleviate the drought in most areas.
After two snowfalls on February 9-10 and 12-13, precipitation in central Tangshan, northern Langfang, central Baoding, major parts of Shijiazhuang, northeast and southwest of Hengshui, central and eastern Xingtai, western Yunnan and eastern wheat ~7.7 mm, which has an effect on the growth of wheat fields; the precipitation in the northeast of Qinhuangdao, the southeastern part of Baoding, and the western part of Zhangzhou is less than 1 mm, which has little effect on soil growth in other wheat fields; the precipitation in other wheat areas is mostly 2 to 3 mm. The soil surface of the wheat field is slightly increased.
According to the field investigation of Shijiazhuang wheat area after 13 days of snow, the wintering condition of winter wheat in Shijiazhuang wheat area is still normal, the snow in the wheat field is basically melted, and the soil surface is obviously increased; but the other wheat with less precipitation (below 2 mm) The area has little effect on the growth of wheat fields.
According to the latest data analysis, it is expected that in the next week, except for weak snowfall (about 1 mm) in the northern region on the 16th, most of the province will be dominated by sunny to cloudy weather. There will be no obvious snowfall and the drought will continue. All localities and departments should conscientiously implement the spirit of the National Grain Production Conference and the Provincial Flood Control and Spring Management Conference, continue to do a good job in drought relief, and strengthen the management of wheat fields. Based on current agricultural production conditions and future weather, it is recommended that:
1. After the snow melts in the wheat area, use the sunny and warm weather to make timely plans, break the knots, make up the gaps, increase the temperature and protect the mites, and promote the early germination of the winter wheat. At the same time, the seedlings should be checked in time, and the seedlings should be classified and managed. To ensure the normal growth of wheat in spring.
2. Facility agriculture should be well insulated and windproof. At the same time, the snow on the shed film should be cleaned in time to keep the shed film clean.
