【摘要】 应用三元二次通用正交旋转组合设计法对林业常用除草剂农达 (Glyphosate)、阿特拉津 (Atrazine)及百草敌 (Dicamba)三元混用的最佳配比进行了初步探讨 ,建立了以株防效为目标函数的数学模型。经相关检验分析 ,模型的拟合度很好 ,能够用来进行预报。应用DPS软件进行模拟寻优 ,在防效大于 80 %限定条件下 ,共选出2 5个最佳配比方案 ,在 95 %最佳配比分布区间内 ,其配方控制范围分别为 :6 4.874～ 72 .2 70mg/m2 ;6 1.745～74.5 13mg/m2 ;7.0 6 8～ 9.2 5 8mg/m2 。更多还原

【Abstract】 By means of commmonly used rational regression design method, the most appropriate ratio of three forestry herbicides is approached. The mathematical model is established between the dosage of Glyphosate, Atrazine, Dicamba and plant efficacy. Tested by relative analysis of variance, the model has a good reliability and can be popularized. Imitated by computer, it is concluded that the best ratio of above three forestry herbicides are Glyphosate (64.874～72.270 mg/m 2), Atrazine(61.745～74.513 mg/m 2), Dicamba(7.068～9.258 mg/m 2).更多还原
