简要综述了土壤活性有机质及其应用的研究进展 ,包括活性有机质的概念及其测定方法、活性有机质与土壤养分供应、土壤理化性质的关系及其活性有机质在反映土壤肥力综合评价土壤质量等方面的应用。在此基础上 ,通过对果园土壤活性有机质含量测定 ,研究了其对果园土壤以及果实的影响 ,提出了固本培源 ,因地制宜增加果园土壤活性有机质的对策。 This paper briefly reviewed the research progress of active soil organic matter and its application, including the concept of active organic matter and its determination method, the relationship between active organic matter and soil nutrient supply, soil physical and chemical properties and its active organic matter in reflecting soil fertility and evaluating soil quality comprehensively application. On this basis, through the determination of active soil organic matter content in orchard, the impact of orchard on the soil and fruit were studied, and the countermeasures for increasing soil active organic matter in orchard soil according to local conditions were put forward.
