Embodiment 1
[0020] Mix 700kg of calcium magnesium phosphate fertilizer and 800kg of ammonium sulfate uniformly to obtain the core layer of compound fertilizer; use 20kg of liquid organic carbon with an organic matter content greater than 40%, and use the coating machine spraying system to spray evenly on the core layer of 1500kg of compound fertilizer at a temperature of 80°C On the surface, make the oily coating material completely cover the core layer of the compound fertilizer, and the residence time of the material in the barrel is ≥5min; finally, 40kg of insecticidal fungal powder (30kg of Paecilomyces lilacinus , 5kg amylase bacillus, 5kg bacillus subtilis) are evenly sprayed on the surface of the oily coating material, and the microbial coating composite fertilizer A is prepared.
Embodiment 2
[0022] Mix 500kg of ferrous sulfate, 500kg of zinc sulfate, and 500kg of potassium sulfate evenly to obtain the core layer of compound fertilizer; 15kg of liquid organic carbon with an organic matter content greater than 40% is evenly sprayed on 1500kg The surface of the core layer of the compound fertilizer, so that the oily coating material completely covers the core layer of the compound fertilizer, and the residence time of the material in the barrel is ≥ 5 minutes; finally, 30 kg (20 kg of Paecilomyces lilacinus, 5kg amylase bacillus, 5kg bacillus subtilis) insecticidal functional bacteria powder is evenly sprayed on the surface of the oily coating material, and the microbial coating compound fertilizer B is prepared.
