[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.
