赤霉病杀菌剂混合比例的单形重心设计研究

Study on Mixture Ratio of Effective Fungicides on Wheat Scab by Simplex-barycenter Design

采用单形重心设计法研究了多菌灵、三唑酮、甲基硫菌灵不同混合比例防治小麦赤霉病。在抑菌率大于80%的约束条件下,从3种供试药剂任意两种混合的方案中筛选出27种优化混合比例。

Adopting the simplex-barycenter design. optimal mixture ratio among carbendazim and triadimefon and thiophanate-methyl which control wheat scab were studied in this paper. Under bacteriostatic ratio was larger than 80%,by arbitrarily mixing two kinds of three trial fungicides,27 kinds of optimal blending proportions were selected.
