【摘要】 蚯蚓粪是优质天然的生物有机肥，能有效改良障碍土壤。当前对蚯蚓粪的研究主要集中在土壤肥力、作物生长等方面，而关于盐碱土壤修复的研究较少。通过归纳并总结蚯蚓粪的性质，结合蚯蚓粪在盐碱地的应用情况，从盐碱土壤理化性质、土壤肥力、作物生长3个方面阐述了蚯蚓粪修复机理的研究现状，综合分析了研究的局限性并提出了相应的展望。更多还原

【Abstract】 Earthworm dung was a natural biological organic fertilizer that plays an important role in improving barrier soils.Currently, research on earthworm dung mainly focuses on soil fertility, crop growth, and other aspects, while research on saline and alkaline soil remediation was less. By summarizing the properties of earthworm dung and combining its application in saline and alkaline soil,expounded the current research situation of earthworm dung remediation mechanism from three aspects: physical and chemical properties of saline and alkaline soil, soil fertility, and crop growth, comprehensively analyzed the limitations of the research, and put forward corresponding prospects.更多还原
