THE ROLE OF MICROORGANISMS IN SOIL SALINIZATION REMEDIATION

Saline soil is one of the main forms of soil degradation, covering approximately 1 billion hectares globally. It is mainly found in Russia, the United States and China. Climate warming and improper irrigation practices have accelerated the salinization of the soil, posing a threat to crop productivity. In recent years, microorganisms, as an important part of the natural cycle, have been playing an increasingly significant role in the restoration of soil salinization. However, a comprehensive bibliometric analysis of this field has not yet been performed. Here CiteSpace, VOSviewer and the Bibliometrix R package were used to predict future trends in this field. The results showed numbers of published papers on the role of microorganisms in soil salinization remediation is increasing year by year. Functional microorganisms play a crucial role in restoring saline-alkali wetlands by regulating the expression of plant salt-tolerance genes and improving the soil microenvironment. Future research will focus on designing synthetic microbial communities, analyzing multi-omics interaction networks, and jointly enhancing the efficacy of ecological restoration and carbon sequestration, providing innovative solutions for the sustainable management of saline-alkali wetlands.
