摘　　要：通过设置不同氮磷钾肥配比进行了田间试验,分析了不同施肥处理对油菜产量及其构成因子的影响。结果表明,合理配施氮磷钾肥能显著提高油菜产量,其中氮磷配施效果最佳,氮磷钾均衡施用处理组的产量提升最为显著,且不同氮磷钾肥配比处理对油菜产量构成因子也产生了显著影响。In order to investigate the effects of different N,P and K ratio on Brassica napus yield,field experiments were conducted to systematically analyze the effects of different fertilization treatments on Brassica napus yield and its constituent factors.The results showed that rational application of N,P and K fertilizer could significantly increase the yield of Brassica napus,among which N,P and K fertilizer combination had the best effect.Compared with no fertilizer treatment,the yield of balanced application of N,P and K was the most significant increase.Further analysis showed that different nitrogen,phosphorus and potassium fertilizer ratio treatments also had significant effects on the yield components of Brassica napus.
