in the second step, removing impurities from the ammonium sulfate, ammonium dihydrogen phosphate, potassium chloride, calcium magnesium phosphate, urea and activated sludge weighed in the first step, removing impurities from the raw materials, and pouring the sucrose complex iron, the sucrose complex zinc and the sucrose complex magnesium into the same container for stirring to uniformly mix the sucrose complex iron, the sucrose complex zinc and the sucrose complex magnesium, thereby preparing a sucrose salt complex; pouring nitrohumic acid boron and nitrohumic acid molybdenum into the same container, and stirring to uniformly mix the nitrohumic acid boron and the nitrohumic acid molybdenum so as to prepare nitrohumic acid; activating the strains of the puffball fungi, the azotobacter, the phosphate solubilizing bacteria and the potassium solubilizing bacteria, pouring the activated puffball fungi, the azotobacter, the phosphate solubilizing bacteria and the potassium solubilizing bacteria into a same container, and stirring to uniformly mix the puffball fungi, the nitrogen fixing bacteria, the phosphate solubilizing bacteria and the potassium solubilizing bacteria so as to prepare a microbial preparation; preparing 20-30% of ammonium sulfate, 15-20% of ammonium dihydrogen phosphate, 6-10% of potassium chloride, 10-15% of calcium magnesium phosphate fertilizer, 9-14% of urea, 8-14% of activated sludge, 5-8% of sucrose salt complex, 6-11% of nitrohumic acid and 1-3% of microbial agent, and standing for later use;
in the third step, the activated sludge subjected to impurity removal in the second step is dried, the dried activated sludge, ammonium sulfate, ammonium dihydrogen phosphate, potassium chloride, calcium magnesium phosphate fertilizer and urea are respectively and independently crushed, the knotted raw materials are crushed into particles, and the crushed raw materials are ground again to enable the particles to be ground into powder;
in the fourth step, the powdery raw materials prepared by grinding in the third step are mixed, ammonium sulfate, ammonium dihydrogen phosphate, potassium chloride, calcium magnesium phosphate, urea, activated sludge, a sucrose salt complex, nitrohumic acid and a microbial preparation are sequentially put into a stirring tank for mixing the raw materials, the raw materials are uniformly mixed in the stirring process, a large amount of smoke is generated in the stirring and mixing process of the raw materials, and the smoke is sprayed and settled by spraying water into the stirring tank;
in the fifth step, the mixed material prepared in the fourth step is transferred to a granulator for fertilizer granulation, and the volume of the prepared fertilizer particles is the same in the granulation process;
in the sixth step, the fertilizer granules prepared in the fifth step are collected, and because the granulated fertilizer granules have high moisture content, the fertilizer granules need to be dried and dewatered, and the fertilizer granules are placed into a dryer for low-temperature drying, so that the dryer can effectively remove redundant moisture in the fertilizer granules;
and step seven, screening the fertilizer finished products prepared in the step six, crushing and rebuilding the fertilizer with larger particles and smaller particles in the fertilizer finished products, and bagging the fertilizer with qualified volume for storage.
