Study on Fertilizer Effect for High-yielding Cultivation of Rape

Qian Yu-bao

Abstract

Using'3414'fertilizer effect experiment,the effect of nitrogenous(N),phosphate(P),potash(K) fertilizer on rape yield in Dongzhi County was researched.The function model of fertilizer effect was set up.The results showed that the supply capacity of N P K fertilizer were above the middle level,treatment of adding P fertilizer reached the best result to improve rape's yield,but the increase effect of using N K fertilizer were not significant.The optimum rate of N,P2O5 and K2O for rape were 24.53 kg/hm2,77.65 kg/hm2 and 4.66 kg/hm2,respectively.
