土壤是有生命的,这个生命就是土壤微生物。大家知道,土壤是微生物的大本营,是微生物生长和繁殖的天然培养基。腐植酸贯穿于土壤生命之中,是土壤的“生命核”。没有腐植酸,土壤将失去活性。据此,厘清“土壤—腐植酸—微生物”之间的关系,对保护国土资源、促进土壤可持续生产具有重要的现实意义。1土壤腐植酸 Soil is life, this life is soil microorganism. We all know that soil is a stronghold of microorganisms and is a natural medium for the growth and reproduction of microorganisms. Humic acid throughout the soil life, is the soil “life nuclear ”. Without humic acid, the soil will lose its activity. Accordingly, clarifying the relationship between “soil-humic acid-microorganism” is of great practical significance for the protection of land and resources and the promotion of sustainable soil production. 1 humus soil
