    Abstract:

    In this experiment, bacterial bran, sulfur and humic acid were used as the modified matrix.The combination of Auricularia auricula bran + sulfur + humic acid was mixed with saline-alkali soil, saline-alkali soil was used as control, and its effects on physical and chemical properties of saline-alkali soil and the growth and development of puccinellia were studied.Physical index, chemical index, nutrient index and growth and development index of soda saline-alkali soil were analyzed.The results showed that the bulk density and soil pH decreased by 22.38% and 20.13% compared with the CK treatment.The effect of compound modifier on soil exchange sodium and exchange sodium percentage was 63.78% and 63.99% lower than that of CK treatment, respectively.The compound modifier increased the content of soil organic matter, alkali-hydrolyzed nitrogen, available phosphorus and available potassium, and significantly promoted the growth index of alkali fescue plants.The application of compound modifier to soda saline-alkali soil improved the physical and chemical properties of soil, promoted the growth of alkali fescue and increased the biomass.Based on the data of soil physical and chemical indexes and crop growth indexes, the best improvement effect was the treatment of C6, which included 20 g/kg bacterial bran, 6 g/kg sulfur and 2 g/kg humic acid.
