[0043] Example 1

[0044] (1) Crush the phosphate iron ore into particles with a particle size of 40 mesh, weigh the crushed iron phosphate and heat it to 200℃, keep it for 1h, continue to heat up to 600℃, keep it for 2h, take it out, cool it and put it in a desiccator spare;

[0045] (2) Collect the monosodium glutamate fermentation tail liquid discharged from a factory, adjust the pH value to 6, concentrate, and reduce the volume to 40% of the solid content, and then use the centrifugal spray drying method to produce dry solid powder with a particle size of 10 The target particles are reserved;

[0046] (3) Collect chicken manure from a chicken farm, sprinkle it with 0.1% urea and 5% superphosphate, and then compost it, and use a stick to vent holes in the pile, cover it with plastic cloth for heat preservation and fertilizer, and turn the pile once after 10 days of retting , After 60 days of retting; then put the organic fertilizer on a sterile plastic film, flatten it, cover it wi

[0049] (1) Crush the phosphate iron ore into particles with a particle size of 40 mesh, weigh the crushed iron phosphate and heat it to 400℃, keep it for 2h, continue to heat up to 700℃, keep it for 1h, take it out, cool it, and put it in a desiccator spare;

[0050] (2) Collect the monosodium glutamate fermentation tail liquid discharged from a factory, adjust the pH value to 8, and concentrate it to reduce the volume to 60% of the solid content, and then use the centrifugal spray drying method to produce dry solid powder with a particle size of 30 The target particles are reserved;

[0051] (3) Collect chicken manure from a chicken farm, sprinkle it with 0.5% urea and 2% superphosphate, and then compost it. Use a stick to vent holes in the pile, cover it with a plastic sheet for heat preservation and compost, and turn the pile once after 10 days of retting. , After 90 days of composting; then put the organic fertilizer on a sterile plastic film, flatten it, cover
