Abstract: In order to solve the problems of low soil fertility, nutrient unbalance, the weak ability of comprehensive production of maize after land consolidation in the west of Jilin Province. The experiment by several main maize fertilizer level, determined the relationship between fertilizer and maize production through mathematical model and the best fertilizer rate of various kinds of fertilizers. The results of field experiment showed that: the application model of N, P, K and the micronutrient fertilizer about S, Zn were in line with the quadratic curve y=ax2 bx c after land consolidation. Using the model, considering the amount of application and maize yield, we had cleared about the application rate of N, P, K and the micronutrient fertilizer about S, Zn at the maximization of maize production. That was N: 198.02 kg/hm2; P2O5:107.36 kg/hm2; K2O: 75.32 kg/hm2; S: 48.72 kg/hm2; Zn: 38.35 kg/hm2.
