摘　　要：采用正交设计L_(9)(3^(4)),研究了不同氮磷钾用量和种植密度对春油菜产量的影响。结果表明,密度对于油菜的产量具有极显著的影响,种植密度在6000株左右的产量与其他密度处理存在极显著差异,效果最好。多重结果表明,M2N1P2K3配合施用效果好。密度和氮肥对油菜产量影响较大,检验结果达到极显著差异。The orthogonal design L_(9)(3^(4))was used to study the effects of different N,P,and K dosages and planting densities on the yield and crude fat content of spring oilseed rape.The results showed that density has a very significant effect on the yield of rapeseed,and the yield of planting density of 6000 plants per mu is extremely difierent from other density treatments,and the effect is the best.Multiple results show that the combined application of M2N1P2K3 has a better effect.Density and nitrogen fertilizer have a greater impact on rape yield,and the test results are extremely significant.
