麦蚜最优动态生防指标研究

Study on Optimal Dynamic Thresholds of Biological Control in Wheat Aphids

本文在田间试验的基础上建立了麦蚜为害损失的Weibull 模型,运用模糊最优化原理提出了在不同经济和生态效益情况下,麦蚜最优动态生防指标模型,以及小麦不同生育期麦蚜的最优动态生防指标模型。

On the basis of experiment in the fields,a Weibull model of wh-eat aphids damage is established,Models of optimal dynamic thresholds ofbiological control in wheat aphids are offered for different stages of wheatunder different econ—ecological benefits by using fuzzy optimal theory.
