Halophyte Planting Improves Saline-Alkali Soil and Brings Changes in Physical and Chemical Properties and Soil Microbial Communities

Highlights-Halophyte planting has a significant impact on the restoration of saline-alkali soil, and provide reference methods for the biological improvement of saline-alkali soils • halophyte planting has affected soil microbial structure, and the effect of Sphaerophysa salsula (Pall.)DC. is prominent.-Proteobacteria plays a crucial role in the degradation of soil organic matter, which may be an important factor in improving saline-alkali soil.-Halophytes interact with soil microorganisms to repair soil salinity.
