摘　　要：用二次回归旋转组合设计研究了基本亩数（X_1）、基苗氮肥（X_2）、孕穗期氮肥（X_3)、过磷酸钙（X_4）和氯化钾（X_5）用量对小麦籽粒蛋白质含量的影响．结果表明，X_4、X_1和X_2对蛋白质含量有显著作用，因素之间存在着复杂的互作效应．利用计算机模拟选优，获得了本试验条件下蛋白质含量大于13％的5个农艺因素组合方案，X_1=172.35～186.75万／ha；x_2=116.6～123.6kg／ha；x_3=33.75～39.15kg／ha；x_4=333.9～448.8kg／ha；x_5=190.65～233.10kg／ha．The effect of plant density (x_1)、N rate applied before sowing and at seedling stage (x_2),N rate applied during booting stage (x_3)、applied superphosphate rate (x_4) and potassium chloride rate (x_5) on protein content (PC)) in wheat grain was investigated in commonly used、rotational and combinatoral design of quadratic regression.The results showed that x_4、x_1 and x_2 have significant effect on PC,and that there is complex interaction among the studied agronomic factors in their action on PC.The optimized agronomic scheme for higher than 13% of PC was obtained through simulation and optimization by using regression equation of PC and agronomic factors on computer.
