摘要
实验证明 ,蚯蚓对有机废弃物进行生物降解的产物—蚯蚓粪 ,在一定程度上能够控制一些蔬菜类植物苗期土传病害的发生 .对此现象的一种解释是蚯蚓粪中含有一些拮抗微生物 .从以牛粪为饵料生产的蚯蚓粪中分离出两株拮抗活性强、范围广的拮抗微生物并得到鉴定 :0 10 3A球孢链霉菌 (Streptomycesglobisporus)和 0 10 4A丁香苷链霉菌 (Strepto mycessyringini) .该菌及其发酵液对多种病原菌的抑菌谱及胚根、盆栽生物测定实验表明 :两株拮抗菌在蚯蚓粪对蔬菜苗期病害的控制中起重要作用 .表 8参
s Vermicomposting is the biological degradation of organic wastes by earthworms. Studies showed that the end product, known as vermicompost can suppress soilborne plant diseases in some degree. One possible explanation to this phenomenon is that they contain some microorganims suppressive to pathogens. Two antimicroorganisms from suppressive vermicompost were isolated and identified by Institute of Microbiology, Chinese Academy of Sciences. Suppressive spectrum of either their agar or their fermentation liquid against several phytopathogenic fungi both in vitro and in viro was also investigated. All those suggested that the two antimicroorganisms were partly responsible for the suppressive effect of the vermicompost. Tab 8, Ref 17
