玉米授粉后,即开始进入灌浆成熟的生育后期阶段,这期间切实加强田间“六项”管理,对加速灌浆,促使早熟,提高粒重,增加产量极为重要。一、割除“空秆”。人们常把没有长出雌穗和虽有雌穗但到秋只是个青棒或瞎棒的玉米植株,统称为空秆,在一般的年份里,这种空秆对产量影响很大。这 Corn pollination, that is, began to enter the late maturity stage of grain filling, during which to effectively strengthen the field of “six” management, to accelerate the filling, to promote premature, increase grain weight, increase production is extremely important. First, cut off the “empty stalks.” People often do not grow the female spike and although the ear, but the autumn is only a green bar or blind stick corn plants, collectively referred to as empty stalks, in general years, the empty stalks have a great impact on the yield.
