当前,“立春”已过,天气回暖,正是加强麦田管理、构建合理群体的关键时期。今年冬小麦苗情、墒情总体较好,但偏旺和偏弱“两头苗”现象较为突出,遭遇早春低温冻害的威胁较大。要以“控旺促弱保壮,科学运筹肥水,防控病虫草害,突出防灾减灾”为技术路径,因地因苗搞好春季麦田管理,夯实夏粮丰收的基础。其中,长江中下游地区小麦陆续开始返青,部分地区进入起身期,是苗情差异最大、最复杂的地区。旱茬小麦苗情较好,但 At present, “Spring ” has passed, the weather is warmer, it is to strengthen wheat field management, build a reasonable period of a critical period. This year’s winter wheat seedlings, the overall moisture content is better, but the partial Wang and weak “two heads ” phenomenon is more prominent, experience low temperature frost damage in early spring threat. It is necessary to take the principle of “promoting prosperity and weakness by science and technology, scientific management of fertilizer and water, prevention and control of pest and disease, and prevention and mitigation of diseases” as the technical route. Among them, the wheat in the middle and lower reaches of the Yangtze River began to turn green one after another, and some areas entered the period of getting up, which is the area with the largest and most complicated seedling differences. Dry stubble wheat seedlings better, however
