| 摘 要： | 利用现代肥料二次回归"3414"设计,对春玉米施肥参数进行了研究。结果表明:通过三元二次肥料效应函数获得的最高产量在各类型函数中最低,投入的肥料价值也最低,获得的产投比较高;通过一元二次肥料效应函数获得的最高产量最高,其中K处理一元二次肥料效应方程获得的最高产量和产投比最高。各类型函数所获得的最佳经济产量表现为:一元函数>二元函数>三元函数,但三元二次肥料效应函数所获得的产投比远远高于其他函数,可用于推荐施肥。通过三元二次肥料效应函数获得的春玉米推荐施肥指标为:N162.8kg/hm2,P2O5112.7kg/hm2,K2O149.7kg/hm2,需要投入的肥料成本为1776元/hm2,可获得最佳经济产量13241kg/hm2,产投比高达7.45。

| Abstract: | In this study,"3414" fertilizer experiment design was applied to calculate the fertilization parameters for spring maize.The results showed that the maximum output calculated from three-factors model was the minimum in the 7 kinds of functions,its investment of fertilizer was the lowest,and the ratio of production and invest was higher than the others.The maximum output calculated from one-factor model was the maximum,in which the maximum output and the ratio of production and invest calculated from K-one-f... |
