Soil conditioner prepared by activating phosphate rock tailings by using organic/inorganic activators and preparation method thereof

The invention relates to a soil conditioner prepared by activating phosphate rock tailings by using organic/inorganic activators and a preparation method thereof. The soil conditioner is prepared by taking phosphate rock tailings as raw materials through carrying out mixed grinding on the phosphate rock tailings so as to activate the phosphate rock tailings in an organic-inorganic combined activation mode, in such a way, the influence of impurities in the phosphate rock tailings is overcome, so that low-content calcium, magnesium, phosphorus, silicon and iron in the phosphate rock tailings are fully activated, and then released into elements which can be effectively utilized by plants, therefore, the product has rich silicon, calcium, magnesium, nitrogen and phosphorus elements and the like, and has a good effect on the improvement and conditioning of acidic soil. The method has the advantages of simple operation, easily available raw materials, good product quality, simple reaction process, environmental friendliness, and the like.
