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。该区南部小麦已返青,中北部还处于越冬期,苗情和墒情总体好于去年。但部分地区因播期偏早,播量偏大,加之冬季气温偏高,旺长现象
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. Wheat in the southern part of the area has rejuvenated, while central and northern parts are still overwintering. Their overalls and soil moisture are generally better than last year. However, some areas due to earlier sowing, sowing is too large, combined with the high winter temperatures, Wang Long phenomenon
