Abstract:: ‘Xiangling’precocious walnut was used as experiment material to study the effect of characteristics and yield of walnut according to the theory of “3414” regression optimum design,in order to obtain high yield and high quality walnut of ‘Xiangling’.The results showed that P was key factor affecting the development of kernels,and N,P and K had a slight effect on the average weight of walnuts.The different proportions of N,P2O5 and K2O had a great impact on the indexes of walnut by comparing with CK.Taking into account the ratio of fertilizer to improve the size of the three diameters of nuts,the nutrition of kernels and the content of N,P and K in the leaves,that treatment 10 (applying N,P2O5,K2O each plant for 0.990 2、0.660 1、0.990 2 kg) had the best fertilization effect.
