为了提高塑盘旱育秧免耕撬窝移栽模式下分蘖迟,主茎和分蘖穗齐穗时间、成穗质量、穗子大小差异大,产量不高的问题,从合理氮肥运筹的角度研究表明:本田施用氮165 kg/hm2,采用底肥、追肥、穗肥用量比5∶3∶2的运筹方式,可以促长早生分蘖,提高群体素质,促进分蘖生长,缩小主茎和分蘖穗之间的差异,提高穗子质量和整齐度,从而提高产量。
In order to improve the problem of late tillering, tillering time of main stem and tillering panicle, ear quality, big difference of ear size and low yield under transplanting mode of no plastic tillage pry nest with plastic tray, Honda applied nitrogen 165kg / hm2, using base fertilizer, topdressing and panicle fertilizer ratio of 5: 3: 2, it can promote early tillering, improve population quality, promote tillering growth and reduce the difference between main stem and tillering spike , Improve the quality and uniformity of the ears, thereby increasing the yield.
