摘　　要：研究表明，在高产条件下，每亩１０万、１５万、２０万基本苗的处理，随密度增加，挑旗后叶面积系数、旗叶叶绿素含量、群体光合速率下降，干物质向籽粒中的分配比率减少，穗部性状变劣，但每亩１５万基本苗的处理与每亩１０万基本苗的处理相比无显著差异，在较高生物产量的基础上。Under the density 150×10 4,225×10 4 and 300×10 4 of essential seedlings per hactare,Leaf area coefficient,chlorophyll content in the flag leaf,population photosynthetic rate and distribution of dry matter to seed decreased after flag stage with the density increasing,and the spike characters got worse There was no significant difference between the two tratements of 225×10 4 and 150×10 4 essential seedlings per hactare As a result,higher economic coefficient was needed to get 9tha grain,based on higher biological yield
