Abstract: The aim of the article is to investigate the effects on pH, total salt content, organic matter, available potassium and ammonium nitrogen content of the soil after planting Stropharia rugosoannulata in it, and study the improvement on saline-alkali soil by planting S. rugosoannulata. The results showed that compared with the control group CK, the pH value and total salt content of experimental group A in experimental site I and experimental site II were reduced, and the pH of experimental group A in experimental site I was reduced by 2.94% compared with control CK. The total salt content was reduced by 42.36%. Compared with the control CK, the pH of experimental group A in Experimental Site II was reduced by 2.46%, and the total salt content was reduced by 3.08%. Compared with the control group CK, the contents of organic matter, available potassium and ammonium nitrogen in experimental group A in experimental site I and experimental site II increased significantly. Among them, the available potassium in experimental site I increased by 6.17% and ammonium nitrogen increased by 11.85% ; The soil sample available potassium in Experimental Site II increased by 76.77% and ammonium nitrogen increased by 164.39%. It shows that the Stropharia rugosoannulata has a positive effect on improving the physical and chemical properties of saline-alkali soil.

Key words: Stropharia rugosoannulata, coastal saline-alkali soil, soil physical and chemical properties
