采用 D饱和最优回归设计 ,依据试验结果建立以除草效果为目标函数的数学模型 ,综合分析得出 A、B药剂混配 ,对杂草防效及增产作用最高 ;其最佳配比为 A药剂 1 6.4757g/亩 +B药剂1 83.0 0 g/亩。且采用播后苗前土壤处理法防效显著高于茎叶处理法。并对单因素效应和互作效应进行了剖析。
Based on the experimental results, a mathematic model with herbicidal effect as the objective function was established based on the experimental results. The results showed that the mixture of A and B agents had the highest effect on weed control and yield increase. The best ratio was A Pharmacy 1 6.4757g / mu + B Pharmacy 1 83.0 0 g / mu. And after sowing seedling before soil treatment was significantly higher than the effect of stems and leaves treatment. The single-factor effects and interaction effects were analyzed.
