摘　　要：以德油4号为试验材料,利用裂区试验设计,研究了摘苔和N、P、K、B肥施用量、播种量对油菜产量的影响。结果表明:摘苔减产显著,施用尿素20 kg/667m2的单产比施用尿素30 kg/667m2的单产高,施用普钙、氯化钾、硼肥均有一定的增产效果,每窝播4粒种子的单产比每窝播8粒种子的高。The effects of stalk picking, sowing density and amount of N, P, K, B utilization on the yield of rape were investigated using Deiyu 4 by split - plot experiment design. The results showed that stalk picking significantly reduced the yield, and yield using 20 kg/667 m^2 urea was higher than that using 30 kg/667 m^2 urea. Application of superphosphate, potassium chloride or boric fertilizer somewhat increased the yields. Yield of sowing 4 seeds per hole was higher than of 8/ hole.
