Abstract:For the purpose of obtaining Fertilization technical parameters of soil nutrient supply, Crop nutrient absorption capacity, the utilization rate of fertilizer,3414 incomplete tests which deal with 5 facts and repeat 3 times were proceeded in 7 test points on 6 soil types in the city. The results showed that: the effect of N,P,K application is better than the application of N and P, N and K, P and K. The main effects of nitrogen fertilizer mainly through impacting the tiller, plant height, ear length, and so the overall impact on the development of rice production. Phosphate, potash, primarily by impacting the weight of thousand rice grain and the grain production to impact on the development of rice production . the rate of rice production, productivity and the rate between investment and production in different test points nitrogen fertilizer are the highest, followed by phosphate, potash final.
