Drought development in northern Anhui, drought fields should be timely irrigated to replenish water

Since October this year, rainfall in most parts of Anhui Province has continued to be less. The cumulative precipitation from October 1 to November 27 is less than 20 mm along Huaiheibei, and less than 10 mm in the northern part of Huaibei, less than 8-10%. Since October 18, many soil moisture monitoring results have shown that the soil moisture along the surface of Huaihuai River is maintained and developed. Linyi Fertilizer Network Copyright
According to the survey results of various places, although the long-term precipitation along the Huaihe River in Anhui Province is rare, the drought in most areas is limited to the surface layer of the soil. The soil moisture below 10cm is still good, and most of the affected fields have been irrigated 1-2 times, which is effective. The land has alleviated the development of drought, and the current drought has not caused large-scale dead seedlings and seedlings in winter wheat. However, the long-term drought and drought still cause the winter wheat leaves to be thinner and weaker, and the tiller is reduced. The proportion of the first type of seedlings is obviously reduced. Some of the shallow sowing or irrigation is not timely. The field is obviously damaged by drought, showing that the leaves are rolled into a tube and the leaves are yellow. And other symptoms, and there is a lack of seedlings and ridges. Linyi Fertilizer Network Copyright
At present, winter wheat in Anhui Province is generally in the growth stage of pre-winter seedling stage, and winter wheat has entered the tillering stage along the northern part of Huaihuai. As there is no obvious precipitation in late November, the soil loss in the active layer of wheat roots continues to increase, and the drought continues to develop, affecting the normal growth of winter wheat before winter. Although the current drought-preserving and seedling-preserving work of winter wheat in Huaibei has achieved phased results, due to the large arid area and long duration of rain, the surface soil moisture of the winter wheat tiller is poor for a long period of time, and a small part of the dry field is still not With effective irrigation, drought has had an impact on seedling growth and tillering of winter wheat in the main producing areas. Due to the small seedlings and weak seedlings of the winter wheat, the seedlings are biased, which is not conducive to the formation of strong seedlings for wintering.

It is expected that the next week (November 29th to December 4th), Jiangbei, Anhui Province will be dominated by sunny to cloudy weather with no obvious precipitation. The drought along Huaihei River will continue, and there will be an increasing trend. The soil continues to be deaf, and the threat of winter wheat growth and safe wintering is further aggravated. It is recommended that all localities should pay close attention to the changes in soil moisture, and timely irrigate the drought field, replenish water, promote roots and strong roots, and strive for full seedlings and strong seedlings for wintering. .
