摘要： 利用“3414”肥料效应试验，研究了玉米超高产栽培肥料效应及推荐施肥量。结果表明：最佳经济产量，一元二次方程略高于三元二次方程(0.48%)，二元二次方程略低于三元二次方程(-0.05%)； 最佳经济产量施肥量，一元二次方程略高于三元二次方程(1.62%)，二元二次方程略低于三元二次方程(-0.23%)；产投比一元二次方程略低于三元二次方程(0.7%)，二元二次方程略高于三元二次方程(2.17%)。因此，可以采用3 类7 种效应函数求解得到的氮、磷、钾最佳经济产量施肥量的平均值作为推荐施肥量：即氮(N) 300.80 kg/hm2、磷(P2O5) 186.13 kg/hm2、钾(K2O) 218.97 kg/hm2。可获得最佳经济产量14028.0 kg/hm2，产投比为8.27。NPK 互作效应最高，NP、NK、PK 均为正互作，互作效应NP＞NK＞PK。单元素的增产效果是氮＞磷＞钾。

Abstract: 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.
