| 摘 要： | 运用三元二次回归通用旋转组合设计,以对马铃薯宣薯4号产量形成影响较大的栽培措施为决策因子,产量为目标函数,建立栽培密度(X1)、施马铃薯专用肥量(X2)和种薯单薯重量(X3)与产量的数学模型,并通过模拟寻优,提出马铃薯宣薯4号单产3 000 kg/667 m2以上的优化农艺栽培措施量化指标。三因素互作都显示正效应,单因素对产量形成影响呈现种薯单薯重量(X3)>栽培密度(X1)>施马铃薯专用肥量(X2),栽培密度(X1)和施马铃薯专用肥量(X2)的单产呈现单峰值。

| Abstract: | Function of the target variable yield with three independent variables,plant density(X1),application rate(X2) of a fertilizer designed special for potato,and seed tuber size(X3),was created for cv.Xuanshu 4 using the design of ordinary second order rotational regression of three factors,and simulated optimization was made in order to put forward specific measures for yielding 3 000 kg or more based on 667 m2 of land.The interactions of three factors were all positive,and the impact of three factors to yield... |
