| 摘 要： | 试验表明，相同密度不同行株距比例（RS/IS）显著影响水稻群体发展，群体产量、穗数/667m∧2、总颖花量、结实率、午粒重均随RS/IS呈抛物线变化，每穗颖花数、穗颈节间长及剑叶、倒二叶单叶面积则随RS/IS呈线性变化，RS/IS增大，群体内部光照强度境加，光分布趋于合理。

| Abstract: | This experiment showed thatcharacters of rice population were influenced by the ratio of row spacing to intrarow spacing( RS/IS) under the same planting density.The relationship between yield and RS/IS assumed a parabolic change,so did the relationship between panicles/6 6 7m2 ,total spikelets per6 6 7m2 ,setting percentage,or1 0 0 0 - grain weight and RS/IS.The equation between spikelets/panicles and RS/IS was a linear one,so was the equation between rachis internode length,single leaf area( SLA) of the first leaf from the top,or SL A of the second leaf from the top and RS/IS.When RS/IS was on the increase,the intensity of illumination was increased and the light distribution tended to be efficient inside rice population. |
