小麦从返青到拔节、孕穗阶段(即2月下旬到4月下旬),正是增加分蘖,长茎叶,幼穗发育的时期。这一时期的营养条件直接影响到小麦产量。所以要抓好春季麦田管理,做好轧麦、搂麦、施肥、浇水和防治病虫害等工作,才能夺取小麦的丰收。一、适时轧麦:早春轧麦是郊区广大社员多年积累的宝贵经验,是保护小麦不受春冻和保墒的好办法。去年秋播时比较干旱,土壤墒情较差,对小麦春季生长不利,还有不少麦田发生裂缝透风,容易引起风抽死苗。因此,应抓紧时间,在早春(2月中旬前后)土壤表层
Wheat from turning green to jointing, booting stage (late February to late April), it is to increase the tillering, long stems and leaves, panicle development period. The nutritional conditions of this period directly affect the wheat yield. Therefore, we must grasp the management of wheat fields in spring and do a good job of rolling wheat, ramming wheat, fertilizing, watering and pest control and other work in order to win the harvest of wheat. First, timely rolling wheat: Rolling wheat in the early spring is a valuable experience accumulated by members of the public in the suburbs over the years and is a good way to protect wheat from spring freezing and preserving soil moisture. During the autumn last year, the drought was relatively arid with poor soil moisture content, unfavorable to wheat spring growth, and many wheat fields were cracked and air-permeable, which easily led to the wind-pumping of dead plants. Therefore, we should seize the time in the early spring (mid-February around) soil surface
