摘　　要：通过设置花椰菜(Brassica oleracea var.botrytis L.)横向与纵向的氮肥施肥田间试验,来探讨花椰菜最佳氮肥用量和最佳氮肥运筹。结果表明,当花椰菜的氮肥施用量为369.45kg/hm2时,其产量最高,为25 920kg/hm2;在同样磷钾肥背景条件下,氮肥最佳运筹比例为5:5,其产量均高于其他处理。这为上海地区花椰菜科学施肥决策提供了依据。Vertical and lateral field fertilizing experiments were conducted to investigate the best nitrogen（N） fertilizer consumption and application of Brassica oleracea var.botrytis L.in Shanghai.The results showed that N fertilizer of 369.45 kg/hm2 made the vegetable have a yield as much as 25 920 kg/m2.The best Ratios of Base N to Dressing N with the same amount of P and K fertilizer is 5：5,which made the yield more than other treatment.The research results provide a useful and reasonable fertilizing methods for Shanghai area.
