Production method of vermiculite compressed nutrient soil

The invention discloses a production method of vermiculite compressed nutrient soil. According to the main points of the technical scheme, the method comprises the following steps: firstly, acidizing expanded vermiculite and sludge; carrying out stirring, compression and microwave low-temperature sterilization on ingredients of the vermiculite compressed nutrient soil, and then packaging the ingredients into the product, wherein the vermiculite compressed nutrient soil comprises the following raw materials: acidized expanded vermiculite, acidized sludge, soluble sodium silicate, polyvinyl alcohol, ferrous sulfate, turf, flower ceramsite, high-viscosity attapulgite clay, biogas slurry, biogas residues, crushed plant fibers, expanded perlite, super absorbent resin and the like; the vermiculite compressed nutrient soil contains a lot of nitrogen, phosphorus, potassium, organic matters and a plurality of microelements; necessary nutrients for plant growth can be provided; the harms to plants caused by pathogenic bacteria and injurious insects are reduced; normal growth and development of the plants are facilitated; the ecological environment is protected; secondary pollution to the surrounding environment is avoided; and the production method of the vermiculite compressed nutrient soil is suitable for production of different formulas of vermiculite compressed nutrient soil.
