Zusammenfassung:	The invention relates to the technical field of soil treatment, and particularly discloses a saline-alkali soil modifier and a preparation method thereof. The saline-alkali soil improver is prepared by mixing, grinding and sieving 20-30 parts by weight of desulfurized gypsum, 40-50 parts by weight of coco coir and 40-50 parts by weight of bagasse, adding 8-12 parts by weight of a composite biological preparation, 15-25 parts by weight of an oyster shell matrix, 1-3 parts by weight of ammonium dihydrogen phosphate and 0.5-2 parts by weight of potassium humate, and uniformly mixing, through selection and combination of the raw materials in the formula, the saline-alkali soil modifier product has multiple saline-alkali soil repairing functions; by adopting the raw materials in the formula, strictly adjusting and controlling the ratio and achieving the synergistic effect of the raw materials, multiple nutrients are provided, the soil structure is improved, the microbial activity is promoted, and the soil acid-bas
