摘　　要：[目的]确定安徽省贵池地区油菜磷肥的适宜用量范围。[方法]在安徽省贵池地区进行大田试验,在氮、钾、硼肥配合施用的条件下,研究增施磷肥(0、45、90、180 kg/hm^2)对油菜的生物学性状、产量及经济效益的影响。[结果]增施磷肥可促进油菜生长发育,增加油菜产量。随着磷肥的增施,纯收益不断增加,但产投比不断降低。[结论]施用磷肥180 kg/hm^2时,油菜产量效益可达最大化。[Objective]The study aimed to insure the appropriate range of phosphate application rate of rape in Guichi of Anhui Province. [Method]The field test was conducted in Guichi of Anhui Province,in the conditions of npk fertilizer application,the effects of different phosphate fertilizer application amount（0,45,90,180 kg/hm^2）on the biological characteristics,yield and economic effect of rape were studied. [Result]Increasing P application amount could promote growth and development of rape.With the increased phosphate fertilizer facilities,net income increased,but the lower middle class vote rather than constantly.[Conclusion]When P application amount was 180 kg/hm^2,the yield and economic benefits reached maximization.
