本研究应用二次通用旋转组合设计方法,研究了播种期和施药量对稻瘿蚊种群及产量的影响。初步明确播种期是影响稻瘿蚊种群及稻产量的重要因素,播种期适当提前可减少农药的使用量。找到了以产量为目标函数的极值解和最优组合解。
In this study, quadratic universal rotation combination design method was used to study the effect of sowing date and application rate on the population and production of pythium. The initial sowing date is an important factor that affects the population and the yield of rice gall midge mosquito. When the sowing date is appropriate, the use of pesticides can be reduced. Find the extreme solution and the optimal combination solution which take the output as the objective function.
