摘要
初花期喷施不同浓度多效唑,一定程度上抑制了圆叶决明CPI92985(C.rotundifolia)中后期生长,促进了二级、三级有效分枝数和有效结荚数的增加。喷施不同浓度多效唑还有提高叶片叶绿素含量和光合速率的趋势,但每荚粒数和单位面积种子产量却随多效唑浓度的提高而降低。
The growth of CPI92985 (C. rotundifolia) in middle and late period was prohibited on the certain degree when CPI92985 was sprayed with different concentration of PP333 at initial flowering stage, the numbers of effective branches and pods, the content of chlorophyll and photosynthetic rate of CPI92985 increased, but the grain number per pod and unit yield decreased with the increase of PP333 concentration.
