LI Jieli;LIAO Hongqu;YUAN Chen;LIANG Ji;CHEN Mingliang;Shanghai Research Institute of Chemical Industry Co., Ltd.;  
In order to explore the fertilizer efficiency of rice, field plot experiment is carried out using the "3414" design experiment scheme, and the experimental data are analyzed by statistical methods. Experimental results show that external application of fertilizer is indispensable for rice growth and development, and rational application of nitrogen, phosphorus and potassium can improve the botanical traits and yield of rice. Combined with economic benefit and yield, the optimal fertilization amount of local rice is nitrogen(N) 28.04 kg/mu, phosphorus(P_2O_5) 6.72 kg/mu, potassium(K_2O) 0.61 kg/mu, and the ratio of nitrogen, phosphorus and potassium is 1.00∶0.24∶0.02, the rice yield under this condition is about 637.33 kg/mu.
