摘要
采用三因素五水平二次回归通用旋转组合设计,在影响烤烟产量的诸多因子中,选择氮、钾、饼肥作为决策变量,获得3个决策变量(XI)与目标函数(Ya)相互关系的数学模型.分析试验因素效应和交互作用,选出最佳施肥方案.
The secondary regression of orthogonal block design with three factors and five levels was used to select the policy variables in many factors which effected the yield of tobacco. Among which, the N, K and cake fertilizer were selected. The mathmatical models between three policy variables （XI） and objective function （Ya） were obtained and the optimum fertilizer design was selected by analysing the factor effects and interaction.
