Liu Xiang-ling

Abstract

In order to obtain the optimum fertilizing quantity of N,P,K under different types of soil,the experiment of fertilizer in early rice was conducted with 3414 design in Bailu Village,Chengtuan Town,Liujiang County.The results showed that,in the field of middle levels of N,low P and K,application of N 180 kg/hm2,P 60 kg/hm2,K 135 kg/hm2 can reach the highest yield of 6628.5kg/hm2.Regression recommended that the optimum fertilizing quantity of N,P,K is N 140 kg/hm2,P 45 kg/hm2 and K 155 kg/hm2,and the fertilizer ratio is 1∶0.32∶1.1.Combined with the regression analysis and experience,N 140 kg/hm2,P 45 kg/hm2 and K 135 kg/hm2 are strongly recommended.
