    摘要:

    小龄秧移栽、密植或促进大田生长初期营养生长的施氮方法均能增大分离度、大龄秧移栽、疏植或减少大田生长初期施氮量的施氮方法均能减小分离度、生育期短的早季早熟品种易出现重迭型生育型;生育期较长的迟熟品种易出现分离型生育型,感光性强的晚季品种的生育型比早季稻品种更容易受移栽秧龄大小的调节

    Abstract:

    It could increase the separation degree from tillering termination to panicle initiation by transplanting young seedlings with thick space or adopting a nitrogen application system that was able to prolong the vegetative growth period of rice.On the other hand, the separation degree from tillering termination to panicle initiation could be lessened and the overlaping degree enhanced if old seedlings were transplanted, and wide space adopted; or less nitrogen applied in the early growth stage on the main field. The tillering-panicle initiation-overlapping pattem happened usually to the early maturing varieties and the tillering-panicle initiation isolation types could often be seen in the middle or late maturing varieties. Growth pattem of the later-season varieties which strongly sensitive to photoperiod was more easily regulated by the different seedling ages than that of the earlier-season varieties which insensitive to photorerioa.
