| 摘 要： | 为了探索施肥量对冬油菜的影响，研究了不同氮、磷、钾、硼肥施用水平下大田冬油菜生长、产量及养分积累的变化规律。结果表明：施肥能促进冬油菜生长，随着施肥量的增加，收获期油菜氮、磷、钾、硼养分的积累总量提高，同时，冬油菜的产量、养分积累量、肥料利用率的增加幅度减少。

| Abstract: | In order to explore the effects of different fertilizer application levels on winter rapeseed, the variation regularities of winter rapeseed's growth, yield and nutrients accumulation in field under different application levels of nitrogen fertilizer, phosphorus fertilizer, kalium fertilizer and boron fertilizer were studied. The results showed that fertilizer application could promote the growth of winter rapeseed; with the increasing of fertilizer rate, the total accumulation amounts of nitrogen, phosphorus, kalium and boron in winter rapeseed increased in harvest period; meanwhile, the winter rapeseed's yield, nutrients accumulation amounts and increasing amplitude of fertilizer efficiency reduced. |

| Keywords: | winter rapeseed economical characters nutrient accumulation yield fertilizer efficiency |
