| 摘 要： | 本文系统地研究了4种不同种植密度条件下，3种等行距、3种宽窄行共6种株行配置对油菜经济性状和产量的影响差异，结果表明：不同株行距配置方式对密度在15×104株/hm2油菜产量影响不显著，但对密度45×104株/hm2油菜影响达极显著水平，适宜株行距配置增产效果最高达到19.1%；认为20 cm~40 cm的行距配置有利于当前较高密度直播油菜的生产。

| Abstract: | The experiments were focused on investigating the effects of six row spacing on economic characteristic and yield of rapeseed in different plant density. The main results were as follows, there were little significance effect among the six various row-spacing in the planting density of 15 x 104 plant/hrn2, but there were significant difference among the six ones in the density of 45 x 104 plant/hm2, and the maximum yield increased by 19.1%. The experiment results of various row spacing showed that the best row spacing for current direct-seeding rapeseed was 20 cm-40 em one. |
