All localities should seize the opportunity to gradually water up and keep watering

Recently, the wheat expert guidance group of the Ministry of Agriculture went deep into the drought-stricken areas of Hebei, Shanxi, Shandong, Henan, Shaanxi, Gansu, Anhui and Jiangsu provinces to understand the damage situation and analyze the wheat seedlings to guide scientific drought. The expert guidance team leader Yu Zhenwen pointed out during the guidance of the drought-resisting line in Shandong. The precipitation process in the northern winter wheat area tends to end, and the temperature is gradually rising. All localities should seize the opportunity of the average daily temperature reaching 3 °C or above. Drought-resistant watering, slashing and protecting. He pointed out that according to the forecast of the China Meteorological Administration, on the 16th, the average daily temperature in the south of Gansu Province, southwestern Shaanxi, southern Henan and western Anhui will be above 3 °C, suitable for drought-resistant wheat; 17 to 18, suitable for drought resistance The area of ​​wheat has expanded to southern Shandong, Jiangsu, and central and southern Anhui. From 19 to 23, the average daily temperature in the southeastern Shaanxi, southern Gansu, Henan, southwestern Shanxi, southern Hebei, southern Shandong, and northern Susong will also exceed 3 °C, you can water the affected wheat field.

Academician Yu Zhenwen checked the drought and the situation of the seedlings while guiding the farmers to fight drought in the area. For the wheat fields that have not been poured over the winter water, suffered from severe drought, and there are some yellow seedlings or dead seedlings, he told the farmers that the average daily temperature is stable at 3 °C, and the water can be quickly infiltrated after watering during the day. it is good. For wheat fields with drought-induced yellow seedlings, dead seedlings or de-fertilization, he suggested that farmers apply 10 kg of urea per acre combined with watering and increase the application of diammonium phosphate to promote the growth of secondary roots and increase the tillering rate in spring. It is best to use water-saving irrigation technology to fill 40 cubic meters per mu. And when the surface moisture is suitable after watering, timely planing to prevent the loosening of the soil to ensure the growth of roots and tillers. For the dryland wheat fields without hydration conditions, he helped the farmers to implement the crackdown measures. He told farmers that the deeper soil moisture in the soil after the wheat field is suppressed can rise along the capillary to the surface soil, which is beneficial to moisturize the root growth and improve the drought resistance of wheat. At the same time, in the early spring, when the soil is re-slurry or after the light rain, the application of nitrogen fertilizer by chemical fertilizer can increase the number of ears per pan and the number of grains per panicle, which is conducive to increase the yield. In general, about 10 kg of urea is applied. Do not apply phosphate to the base fertilizer. Yu Zhenwen proposed that the water-stained wheat field can be managed in the order of the third type of wheat field and the second type of wheat field.
