[0018] The steps of the implementation method of the present invention are as follows:
[0019] 1. Grind agricultural and forestry wastes and wood lignite to 40-80 meshes respectively, grind mineral catalysts to 60-400 meshes, ground 7 parts by weight of agricultural and forestry wastes, 3 parts by weight of wood lignite and waste for agriculture and forestry After mixing 15% of the mineral catalyst of the total weight of the lignite and the weight of the wood lignite, it is placed in the carbonization reactor, and the reactor is heated to 280-380°C for 2 hours to discharge;
[0020] 2. The mineral catalyst is prepared by the following method: mixing 7 parts by weight of phosphate rock powder, 1 part by weight of pumice, 1 part by weight of serpentine, 0.5 part by weight of medical stone and 0.5 part by weight of bentonite to form minerals catalyst;
[0021] 3. After discharging, cool to room temperature, it is the raw material of carbon-based mineralized active fertilizer; pulveriz...
