摘要
本试验采用三因素五水平回归通用旋转组合设计,在影响烤烟的产值的诸多因子中,选择了氮、磷、钾作为决策变量进行研究。获得了三个决策变量与目标函数(y)相互关系的数学模型。在此基础上进行筛选,提出了我省种植烤烟亩产值500元以上的氮磷钾施用组合方案。
In this paper the design of rotation-regression-general combination was used. Three essential elements -N, P and K were chosen as variable quantity which influenced the output of tobacco. Mathematical models of the relationship between three variable quantities and the objective function(ya) were obtained based on the data of field experiment. The independent and mutual relationship between x_1, x_2, x_3 and ya were analysed. The optimum combinational project was put forward, in which the output value of the tobacco would be more than 500 yuan Renminbi per mu in Hebei Province.
