Compound fertilizer capable of treating soil pollution

The invention belongs to the technical field of chemical industry, and relates to a production formula and manufacturing method of a compound fertilizer. The compound fertilizer is mainly composed of urea, potassium chloride, ammonium dihydrogen phosphate, zinc sulfide, organic sulfur TMT-15, peat and kieselguhr. The compound fertilizer not only contains nitrogen, phosphorus and potassium required by plant growth, but also contains zinc, iron, calcium, magnesium, sodium, silicon, sulfur and other minor elements required by plant production as well as peat capable of improving soil aggregate structure. Besides, the compound fertilizer also contains a complexing agent zinc sulfide capable of being complexed with heavy metals in soil and a chelator organic sulfur TMT-15, which can be combined with mercury, lead, copper, cadmium, nickel, manganese, chromium and other heavy metals in soil to form water-insoluble sulfides, thereby preventing the plants from absorbing the heavy metals in the soil and achieving the goal of treating heavy metals in soil.
