摘　　要：【目的】研究天然黑色素对生物农药的光保护作用,提高生物农药药效,降低农药使用量。为推广天然黑色素在生物农药中的应用提供科学依据。【方法】利用出芽短梗霉MF1发酵获得天然黑色素,在农田小区试验条件下,以生物农药浓度为主处理,黑色素浓度为副处理的裂区试验,确定其最佳配伍,分析其对棉田产量的影响。【结果】当每667 m^2棉田使用Bt 25 g、阿维菌素5 mL、甲维丙溴磷12. 5 g,黑色素2. 5 g时,蚜虫杀死率最大可达到97. 7%,最大棉花产量可达14. 3 kg/小区,显著高于对照小区。【结论】添加天然黑色素不仅可降低生物农药的使用量,同时具有提效增产的作用。【Objective】To investigate the photoprotective effect of natural melanin on biological pesticides,promote efficiency and decrease consumption of biological pesticides.【Method】Melanin broth was obtained by fermentation of Aureobasidium pullulans MF1.Under plot experiment conditions,a split-plot design was conducted to optimize compatibility with the concentration of biological pesticides as the main treatment and melanin concentration as the secondary treatment,and the effect on cotton yield was analyzed.【Result】When the dosage was optimized as follows:Bt 25 g,avermectin 5 mL,propoxybromide 12.5 g and melanin 2.5 g per mu,the maximum killing rate of aphid and the highest yield of cotton were obtained with 97.7%and 14.3 kg per plot,respectively.The results were significantly higher than that of the control plot.【Conclusion】Melanin broth fermented by MF1 can not only decrease consumption of biological pesticides,but also increase the yield of cotton.It has provided scientific basis for further application of natural melanin in biological pesticides.
