近几年秋季阴雨天气较多,气温偏低,大秋作物普遍成熟较晚,致使冬小麦不能适时播种,形成大面积晚茬麦(寒露节以后播种的小麦)。由于晚茬麦在生育期间易受许多不利因素的影响,成熟较晚.粒重不稳,从而导致大幅度减产,使小麦单产的提高受到了很大限制。如何做到 In recent years, more rainy and rainy autumn, the temperature is low, the late autumn crops generally mature, resulting in timely sowing of winter wheat, the formation of large areas of late crop wheat (winter sowing wheat). Because late crop of wheat is susceptible to many unfavorable factors during its growing period, its maturity is late and its grain weight is not stable, which leads to a sharp decrease of yield and the increase of wheat yield is greatly restricted. How to do it
