摘要/Abstract

摘要：

土壤盐碱化已成为全球性生态环境与资源利用问题。我国盐碱地面积广、类型多，其土壤理化性质恶化、微生物功能受抑，严重制约土壤生产力与农业可持续发展。长期单一施用化肥会加剧土壤次生盐渍化，而有机肥部分替代化肥已成为盐碱地改良的重要技术路径。本文综述了有机肥部分替代化肥对盐碱地的改良效应，重点阐述其在调节pH、提升有机质含量与促进团聚体形成、优化土壤养分供应等理化性质方面的改善作用，以及对土壤微生物群落多样性、群落结构及功能微生物的调控机制，剖析了土壤微生物群落与理化性质之间的动态互作关系。同时，指出当前研究存在微生物调控分子机制不明、长期改良效应及环境风险不清、技术集成与区域适配性不足等问题，并展望未来应依托多学科交叉技术，深化协同改良机制研究、加强长期生态安全评估、构建区域适配的一体化改良技术体系。本综述可为盐碱地有机改良技术研发与耐盐碱作物品种培育提供理论依据和实践参考，助力盐碱地资源高效可持续利用。

Abstract:

Soil salinization has become a global issue affecting both ecological environments and resource utilization. In China, saline-alkali land is extensive and diverse, with deteriorated soil physicochemical properties and suppressed microbial functions, which severely restrict soil productivity and sustainable agricultural development. Long-term application of a single type of chemical fertilizer exacerbates secondary salinization, while partial substitution of chemical fertilizers with organic fertilizers has emerged as an important technical approach for improving saline-alkali soils. This review synthesizes the amelioration effects of partial organic fertilizer substitution for chemical fertilizers in saline-alkali soils, focusing on its role in improving soil physicochemical properties requlating soil pH, increasing organic matter content, promoting aggregate formation, and aptimizing the supply of soil nutrients. It also discusses the regulatory mechanisms related to soil microbial community diversity, structure, and functional microorganisms, and analyzes the dynamic interactions between soil microbial communities and physicochemical properties. Meanwhile, the paper highlights current research limitations, such as unclear molecular mechanisms of microbial regulation, insufficient understanding of long-term improvement effects and environmental risks, and inadequate technological integration and regional adaptability. Future research should leverage multidisciplinary approaches to deepen studies on synergistic improvement mechanisms, strengthen long-term ecological safety assessments, and develop regionally adapted integrated improvement technology systems. This review provides theoretical foundations and practical references for the development of organic improvement technologies and the breeding of salt-tolerant crop varieties for saline-alkali lands, thereby supporting the efficient and sustainable utilization of saline-alkali resources.

Key words: saline-alkali land improvement, organic fertilizer substitution, soil microbial community, soil physicochemical properties
