席草“割脑”是夺取高产优质的重要措施,可以减少枯草,提高中期分蘖,防止后期倒伏。“割脑”要注意以下几点:一要掌握季节。太早,前期分蘖茎短,枯黄早,质量不好;太迟,后期分蘖时间短,来不及生长,产量不高。一般以清明前后最好,既能抑制早期分蘖茎的生长,防止倒伏,又可集中养份,促进新芽发育。 Seabuckthron “cutting the brain” is an important measure to seize high yield and quality, can reduce hay, improve mid-term tillering, to prevent late lodging. “Cut brain” should pay attention to the following points: First, to master the season. Too early, early tillering stalks short, yellowing early, poor quality; too late, late tillering time is too short, too late to grow, yield is not high. Generally the best before and after the Ching Ming, both to inhibit the growth of early tillering stems to prevent lodging, but also focus on nutrients and promote the development of new shoots.
