摘要
为探索生防菌的田间最佳施用方式,以多粘芽孢杆菌(Bacillus polymyxa)ZF129和贝莱斯芽孢杆菌(Bacillus velezensis)ZF481为试验对象,比较了生防菌有机肥、生防菌悬浮剂、生防菌与化学药剂协同应用对玉田包尖白菜根肿病的盆栽和田间防治效果。结果表明:生防菌有机肥对大白菜根肿病防效较好,促生作用最好,芽孢1亿个·g^(-1)ZF129和ZF481生防菌有机肥的盆栽防效分别为71.63%和73.18%,田间防效分别为80.68%和79.47%。生防菌悬浮剂与化学药剂氟啶胺、百菌清协同施用后防效显著提高,达到86.58%~95.61%,与化学药剂处理无显著差异。
In order to explore the best application method of biocontrol bacteria in the field,the control effects of Bacillus polymyxa ZF129 and Bacillus velezensis ZF481 on clubroot disease of Yutian Baojian Chinese cabbage were compared in pot and field by application of biocontrol bacteria with organic fertilizer,biocontrol bacteria suspension agent,and collaborative application with chemical agents.The results showed that biocontrol bacteria combined applied with organic fertilizer got a good clubroot disease control effect on Chinese cabbage and the best promoting effect on growth.The control effect of 100 million spores·g^(-1) ZF129 and ZF481 biocontrol bacteria with organic fertilizer was 71.63%and 73.18%in pot,80.68%and 79.47%in field.The collaborative application of biocontrol bacterial suspension agent with chemical agents such as fluridine and chlorothalonil significantly improved the control effect,reaching 86.58%to 95.61%,with no significant difference compared to chemical treatment.
