Due to the influence of warm winter, the area of ​​wheat seedlings in Shandong Province this year is larger. Professor Yu Zhenwen, head of the wheat division of the Provincial Agricultural Experts Advisory Group, proposed that at present, it is imperative to strengthen growth and use spring fertilizer. From September 1 last year to the end of February this year, the average daily temperature of the province was 2.4°C higher than normal, resulting in 17.22 million mu of wheat growing to varying degrees, including 8 million mu of wheat. In an expert meeting organized by the Department of Agriculture of Shandong Province on March 5th, Yu Zhenwen pointed out that the management of wheat fields in the spring is very important. First of all, we must seize the favorable opportunity for the recent rainfall, early planning, warming up and improving the utilization rate of rainwater. Second, timely repression, timely control, and rational use of spring fertilizer, to avoid premature entry jointing period. For Wangmiao wheat field, Zhuangfengan can be sprayed during the start of wheat. The phenomenon of defertilization and yellowing occurs when a type of vigorous seedling wheat returns to the green period. It should be fertilized after returning green to promote its growth. Another type of Wang Miao on the soil with high fertility has no phenomenon of de-fertilization and yellowing. It should be top-dressing and watering. It is expected that the degree of pests and diseases in the spring will be moderately heavy, and preparations must be made early and integrated.
