The fertilizer effect and recommended application amount on super-high-yield summer maize were studied by“3414”fertilizer effect experiment. The results showed that the optimum economic output fitted by quadratic equation with one unknown was higher than that of ternary quadratic equation (0.48% ), binary quadratic equation was slightly lower than that of ternary quadratic equation (-0.05%); application amount of optimum economic yield fitted by quadratic equation with one unknown was higher than that of ternary quadratic equation (1.62% ), binary quadratic equation was slightly lower than that of ternary quadratic equation (-0.23%); output-input ratio fitted by quadratic equation with one unknown was slightly lower than that of ternary quadratic equation (0.7%), binary quadratic equation was slightly higher than that of ternary quadratic equation (2.17%). Therefore, the NPK average application value with optimum economic yield could be obtained from 3 categories 7 kinds of effect functions, which were N 300.80 kg/hm2, P2O5 186.13 kg/hm2 and K2O 218.97 kg/hm2. Then, the best economic yield of 14028.0 kg/hm2 and output-input ratio of 8.27 were obtained. The interaction effect of NPK was the highest, NP, NK and PK were all positive interactions, which followed the order of NP> NK> PK. Yield-increasing effect of single element followed the order of N> P> K.
