Saline-alkali soil repairing novel fertilizer produced by taking high-silicon iron tailings as raw materials

The invention discloses a saline-alkali soil repairing novel fertilizer produced by taking high-silicon iron tailings as raw materials.The fertilizer is prepared by stirring and mixing, by weight, 60-70 parts of the high-silicon iron tailings, 2-8 parts of calcium sulfate, 1-6 parts of zinc sulfate, 1-6 parts of plant ash, 5-12 parts of ammonuim humate, 3-8 parts of potassium humate, 1-6 parts of calcium superphosphate, 5-12 parts of bran, 1-6 parts of ammonium molybdate, 3-8 parts of ferric citrate, 3-8 parts of magnesium sulfate heptahydrate, 2-7 parts of monopotassium phosphate, 1-6 parts of potassium chloride, 14-20 parts of fermented chicken manure, 12-18 parts of fermented sheep manure and 10-15 parts of oyster shell powder.According to the saline-alkali soil repairing novel fertilizer produced by taking the high-silicon iron tailings as the raw materials, the soil fertility can be improved, and the ventilation, water seepage, fertilizer conservation and water conservation capacities of saline-alkali so
