带叶去雄,是我公司近两年来实行的一项玉米制种新技术。它对保证种子纯度,调节花期相遇,促进提早成熟,增加产量,提前收购调运都有一定作用。 玉米制种抽雄的通常作法是:雄穗露出旗叶后拔掉。有些制种基地面积大,去雄时又正逢两季,一不注意很容易造成“跑粉”,种子纯度很难保证。我公司科技人员经过多次试验,总结出母本超前带叶去雄的办法,效果很好,避免了“跑粉”现象发生。
With leaves to the male, is my company in the past two years to implement a corn seed technology. It is to ensure the purity of seeds, flowering season to meet, to promote early maturity, increase production, early acquisition and transfer have a certain role. The usual practice of maize seeds is: the tassels unplug the flag leaves. Some seed production base area is large, go-between when they coincide two quarters, one can not easily lead to “run powder”, the purity of the seed is difficult to guarantee. After many tests, our company’s scientific and technical personnel summed up the method of removing the male lead in advance with leaves, which worked well and avoided the phenomenon of “running powder”.
