| 摘 要： | 以田间试验研究了秧苗抛栽叶龄对杂交稻分蘖特性及成穗质量的影响 ,探讨了高叶龄抛栽杂交稻产量降低的主要原因。结果表明 :高叶龄抛栽致使杂交稻本田茎蘖高峰期明显推迟 ,单位面积最高茎蘖数和有效穗数量有所降低 ,低位一、二次分蘖穗比例减少且经济性状明显变劣 ,从而显著减产。

| Abstract: | A experiment was conduced in field conditions to determine the effect of scattered-transplanting leaf-age for tilling and panicle quality of hybrid Rice. The result indicated that the raise of scattered-transplanting leaf-age causes the delay of park of tilling, the decrease of the number of panicle and the descend of the economic properties of the effective panicle, which is the principal cause of drop in production of hybrid rice scattered-transplanted in higher leaf-age. |
