| 摘 要： | 本文采用二次回归通用旋转组合设计,研究了玉米青枯病的危害程度与播种密度(X1),施氮量(X2)和施磷量(X3)的关系,并组建了回归模型。结果表明对玉米青枯病病指影响的首要因素是密度,其次是氮,对病指影响的高互效应是X1X2,X1X3。最后对模型进行模拟优化。

| Abstract: | Taking the quadratic regress common rotational cmbination design, we studied the relationship bet-ween the degree of the corn's green withered disease and its sowing desity ,the nitrogenous fertilizer and phosphate fertilizer; and also built the regress model, the experiment result indicated that mainly effecting the index of the corn green withered disease is its sowig density ,then the nitrogenous fertilizer,whose alternate effect to the disease index is x1x2,x1x3 And at last the simulated optimization was made to the model. |
