有机肥部分替代化肥对盐碱地土壤理化性质及微生物群落的调控效应研究进展
Advances in Research on the Regulatory Effects of Partial Substitution of Chemical Fertilizers with Organic Fertilizers on Soil Physicochemical Properties and Microbial Communities in Saline-Alkali Soils
摘要
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.关键词
