| 摘 要： | 不同施氮试验结果表明，施纯氮225kg/hm^2是两系杂交油菜两优586的最佳施氮肥水平，产量达到2396.55kg/hm^2。产量构成因素以单株有效角果数对产量影响较大，每角粒数对产量影响较小。随施氮量的增加，单株一次有效分枝数增加，每角粒数变化较小，千粒重 单株有效角果呈先增后减的趋势。

| Abstract: | The experiment results of different nitrogen treatment showed that the best nitrogen application for two-line system hybrid rapeseed Liangyou 586 was 225kg per hectare, the yield was 2 396.55kg per hectare. Yield components showed that number of pods per plant was most important, seeds per pod had little effect on the yield. As nitrogen increased, number of first branch per plant increased apparently, seeds per pod had little change, 1000-seed weight and number of pods per plant increased firstly and then decreased. |
