摘 要 ：试验表明 ,蚯蚓对农业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蔬菜类植物黄瓜苗期土传病害的发生 ,并表现出明显的促生长效应。蚯蚓粪控制病害的程度与蚯蚓粪的量有一定的关系 ,当蚯蚓粪与土体积比为 2 0 %时 ,控制病害的程度最大 ,防效达 96 .1 %。这种作用主要与蚯蚓粪中的微生物性质有关 ,蚯蚓粪能大大提高土壤中的微生物量和微生物活性 ,从而大大增强了病土中与病原菌进行能源竞争的微生物的竞争能力。同时从新鲜蚯蚓粪中成功分离到拮抗活性强、抗菌谱广的拮抗微生物。初步研究结果说明 ,一般性抑制和特殊性抑制两种机制在蚯蚓粪对病害的控制中起作用。

Abstract:Vermicomposting is a biological degradation of organic wastes by earthworms. Some earthworms can consume a wide range of organic residues such as sewage sludge, animal wastes and crop residues. The end product is known as earthworm cast or vermicompost. Recently, the use of vermicompost as an organic fertilizer for the cultivation of plants has been examined. The aim of this study was to investigate the suppressive effect of vermicompost produced from cattle manure by Eisenia fetida against some soil-borne ...
