METHOD FOR PRODUCING NEW SALINE-ALKALI SOIL REPAIR FERTILIZER BY UTILIZING HIGH SILICON CAST IRON TAILINGS, AND PRODUCTS OF METHOD

A method for producing new saline-alkali soil repair fertilizer by utilizing high silicon cast iron tailings. The method comprises: mixing 820-900 parts by weight of high silicon cast iron tailings, 14-18 parts by weight of calcium sulfate, 8-12 parts by weight of zinc sulfate, 4-8 parts by weight of potassium sulfate, 7-11 parts by weight of iron sulfate heptahydrate, 3-7 parts by weight of calcium superphosphate, 1-5 parts by weight of ferric citrate, 12-18 parts by weight of magnesium sulfate heptahydrate, 10-16 parts by weight of ammonium sulfate, 5-9 parts by weight of ammonium molybdate, 8-12 parts by weight of potassium dihydrogen phosphate, 10-15 parts by weight of ammonium polyacrylate, 210-250 parts by weight of peat nutrient soil and 180-220 parts by weight of humic acid, and treating the obtained mixture by vacuum crushing. The present invention aims at providing a method, which is used for producing new saline-alkali soil repair fertilizer by utilizing high silicon cast iron tailings, can improve
