本文采用五元二次回归正交旋转组合设计,选取播期(X_1)、密度(X_2),施N量(X_3)、施P_2O_5量(X_4)和施K_2量(X_5)五项栽培措施作为决策变量进行研究,获得了五个因素与产量相互关系的函数模型,分析了试验因素的产量效应及其交互作用,筛选出最佳农艺措施组合方案,并进行了经济效益分析。
In this paper, five quadratic regression orthogonal rotation combination design was used to select five cultivation methods of sowing date (X_1), density (X_2), applying N amount (X_3), applying P_2O_5 amount (X_4) and applying K_2 amount The function variables of five factors and the yield were obtained. The yield effects and their interactions of the experimental factors were analyzed. The optimal combination of agronomic measures was screened out and the economic benefits were analyzed.
