摘要

与蚯蚓堆肥相比，蚯蚓洗尚未被认为是一种经济的、生物相容的、促进土壤生物健康的生物资源，尽管大量的蚯蚓洗被视为多余的废物而被拒绝。相比之下，生物功能信息；它的质量和规模是有限的。针对这一问题，将蚯蚓体腔提取物、蚯蚓洗液从两种不同的基质蚯蚓堆肥系统(牛粪；对牛粪+水葫芦)和乳洗液进行微生物学表征以评价其效果。作为第一手报告，改善了理化品质(高腐植酸&；测定了水葫芦蚯蚓堆肥系统蚯蚓洗液中有益菌（溶磷、溶钾、固氮、根瘤菌、氨和氧化亚硝酸盐）的丰度。酶丰富度（荧光素二醋酸酯水解酶、脱氢酶、过氧化氢酶、β-葡萄糖苷酶、磷酸酶等）；芳基硫酸盐酶（Aryl-sulphatase）具有较高的肥力生物学指数，也表明蚯蚓洗作为一种多种生物活性微生物接种物具有改善土壤生物健康的潜力。

Potentiality assessment of vermiwash as a soil microbial inoculum by physico-chemical and microbiological characterization

In contrast to vermicompost, vermiwash has not been considered as an economic, bio-compatible, bio-resource to promote soil biological health, though it is refused in considerable quantity as redundant waste. Comparatively, the information on biological functionality & its quality up scaling of vermiwash are limited. Addressing this issue, the earthworm coelomic extracts, vermiwash from two different substrate vermicomposting system (cow-dung & cow-dung+water hyacinth) and dairy wash liquid were microbiologically characterized to assess the efficacy. As first hand report, improved physico-chemical quality (high humic acid & nutrient content) and abundance of beneficial soil bacteria (phosphate and potassium solubilizing, N₂-fixing, Rhizobium, ammonia and nitrite oxidizing) in vermiwash of water hyacinth incorporated vermicomposting system was registered. The richness of enzymes (Fluorescein diacetate hydrolyzing, dehydrogenase, catalase, β-glucosidase, phosphatase & aryl-sulphatase) with high biological index of fertility also indicated the potentiality of vermiwash to improve the soil biological health as a multi-species bio-active microbial inoculum.
