NOVELTY - Preparing improved base material fertilizer of urban domestic garbage developed soil involves fermenting organic waste; drying fermented rotten organic material, where drying temperature is 160-200 degrees C, where humidity is lower than organic matter 6-8%; grinding organic matter dried, and the powder mesh is 50 meshes; high-temperature sterilizing and far infrared sterilizing organic matter grinded, and the temperature of sterilizing at high temperature is higher than 120 degrees C; adding missing microelement according to different plant need and soil detection.    USE - For preparing improved base material fertilizer of urban domestic garbage developed soil (claimed).    ADVANTAGE - The improved base material fertilizer of urban domestic garbage developed soil can promote the growth of crops, high yield, but also can improve the soil, has simple preparation, low cost, high utilization rate and realizes the sustainable development.    DETAILED DESCRIPTION - Preparing improved base material fertilizer of urban domestic garbage developed soil, involves fermenting organic waste: a municipal solid waste can be used as a base material of the soil added with the local soil and plant close to microbial bacteria and bacteria, stacking the fertilizer cabin within 24 hours to ferment, the temperature is 44-46 degrees C; (2) drying: drying the fermented rotten organic material of step (1), the drying temperature is 160-200 degrees C, the humidity is lower than organic matter 6-8%; (3) powder grinding: grinding the organic matter dried in step (2), and the powder mesh is 50 meshes; (4) sterilizing: high-temperature sterilizing and far infrared sterilizing the organic matter grinded in step (3), and the temperature of sterilizing at high temperature is higher than 120 degrees C; (5) adding missing microelement according to different plant need and soil detection: adding microelement and microorganism strain lack in the soil through an automatic batching system, where the microelement comprises at least one of nitrogen, phosphorus, potassium, zinc, magnesium, calcium, boron, copper; the microorganism strain comprises at least one of methane generating bacteria, ammonification bacteria, anaerobic from nitrogen-fixing bacteria, aerobic from nitrogen-fixing bacteria, potassium bacteria, cellulose-decomposing bacteria, organic pollutant degrading bacteria, photosynthetic bacteria, digestion bacteria, nitrogen-fixing bacteria; stirring: uniformly stirring the base material fertilizer processed in step (5), and storing in an organic matter storehouse for 30 days, the temperature is 35 degrees C; (7) pelleting; (8) drying: drying the granulated base material fertilizer drying till the water is less than 5%; (9) sieving: sieving the base material fertilizer dried in step (8), and the mesh number is 50 meshes; (10) metering; (11) packaging; (12) storing.
