| titleOfInvention | A kind of humic acid-coated slow-release fertilizer and its production process |
| abstract | The invention relates to a humic acid-coated slow-release fertilizer, belonging to the technical field of fertilizer preparation, comprising the following raw materials by weight: 30-50 parts of nitrogen fertilizer, 13-15 parts of potassium fertilizer, 13-15 parts of phosphate fertilizer, 0.2-0.6 parts of trace elements, 10-15 parts of coating materials and 0.1-0.2 parts of microcrystalline wax; the humic acid-coated slow-release fertilizer is prepared by the following steps: placing nitrogen fertilizer, potassium fertilizer, phosphate fertilizer and trace elements in a rotating drum, preheating to 70-75 ℃, add microcrystalline wax, mix for 20-40min under the condition of rotating speed 200-300r/min, under stirring state, spray coating material with spray gun, the obtained product is dried at 75 ℃ to constant weight, cooled to room temperature, to obtain humic acid coating Membrane slow-release fertilizer; by adding modified humic acid, additives and other materials to the coating material, the slow-release fertilizer has a high water retention effect, and can also provide nutrients for crop growth. |
