摘　　要：为筛选白菜软腐病绿色防控应用技术,以极细链格孢激活蛋白和氨基寡糖素复配进行室内毒力及田间药效的测定。在室内联合毒力筛选试验中,使用活体接种法测定极细链格孢激活蛋白和氨基寡糖素单剂,及不同比例复配对白菜软腐病的作用效果。试验发现,供试的5种复配组合均表现出增效,其中极细链格孢激活蛋白∶氨基寡糖(1∶1)配比防治白菜软腐病效果最佳。选择6%寡糖∶链蛋白可湿性粉剂(1∶1),采用田间小区试验,在山东辛集镇、山东大坞镇、湖北武汉新洲区和湖北谋道镇开展田间药效试验。试验表明:处理剂量为75~100 g/667 m^(2)的6%寡糖·链蛋白可湿性粉剂(3%+3%)对白菜软腐病有较好防效(高于65%),且具有较好的增产作用(增产率高达12.16%)。Laboratory toxicity tests and field efficacy trials were conducted to screen green prevention and control technologies for Chinese cabbage soft rot,using a mixture of plant activator protein and amino-oligosaccharin.In the combined toxicity screening tests,an in-vivo inoculation method was used to determine the effects of the plant activator protein and amino-oligosaccharin individually,as well as their mixture in different proportions,against Chinese cabbage soft rot.The results showed that all the five tested combinations exhibited good synergistic effect,with the 1∶1 ratio of plant activator protein to amino-oligosaccharide achieving the best control effect.Field efficacy trials were conducted using 6%oligosaccharides·chain protein(1∶1)wettable powders(WP)in Xinji Town and Dawu Town of Shandong Province,Xinzhou District of Wuhan and Moudao Town of Hubei Province.The results demonstrated that 6%oligosaccharides·chain protein(3%+3%)WP at 75~100 g/667 m^(2)provided a control effect exceeding 65%against Chinese cabbage soft rot and increased the yield significantly up to 12.16%.
