| 摘 要： | 本文运用四元二次回归正交旋转组合设计,在影响旱地小麦产量(Y)的诸因素中,选择播量(X_1)、底磷量(X_2)、底氮量(X_3)、追氮量(X_4)四项栽培措施做为决策变量进行研究,获得了决策变量与目标函数(Y)相互关系的数学模型。并在此基础上,通过计算机模拟寻优,确定了亩产300kg以上的优化栽培措施方案:播量7.1—8.6kg底施过磷酸钙37.5—46.3kg,底施尿素11.8—15.7kg。

| Abstract: | By means of the combination design of qurternary quadretic regression orthogonal ratation , chasing rate (x1), bast phosphate fertilizer ( X2 ), base nitrogenous fertilizer (x3) ,and top nitrogenous fertilizer (x4) application as the decision variables to make researches on the factors affecting wheat's productivity(Y)in the upland field, this paper give the mathematical model of the object function (y) and decision variables. On this basis,the paper defines the optimum cultural measurements through the simulating optimization by computer, its seading rate: 7. 1-8. 6kg, base calcium peroxydiphosphhate fertilizer 37.5-46. 3kg and base urea fertilizer 11. 8-15. 7kg |
