| 摘 要： | 采用小区对比试验方法,探讨了不同基本苗对水稻新品种桥科951生育及产量的影响。结果表明,该品种单位面积收获穗数、齐穗期叶面积指数、齐穗期干物质积累量与基本苗数呈正相关;茎蘖成穗率、齐穗期有效叶面积率、高效叶面积率、齐穗后干物质积累量占籽粒产量的百分比、收获指数与基本苗数呈负相关;单位面积颖花量、成熟期干物质积累量与基本苗数呈多元相关。基本苗80.85万/hm2的J4处理获得单产9.49t/hm2,比处理J3、J5、J2、J6分别高1.4%、2.4%、4.4%、5.9%。

| Abstract: | Comparative tests method were applied on the effect of different basic planting density on growth and yield of new rice cultivar Qiaoke 951.The results showed that panicles,leaf area index,dry matter at full heading stage showed positively correlated to basic planting density of the cultivar.The effective tillers rate,effective leaf area rate,high effective leaf area rate,percentage of dry matter for grains after heading,harvesting index were negatively correlated to basic planting density.Spikelets,dry matter for basic planting density showed a multiple correlation.Basic planting density 808,500/hm2 of J4obtained yields 9.49t/hm2,1.4%,2.4%,4.4%,5.9% higher than treatments J3,J5,J2,J6,respectively. |
