| titleOfInvention | Slow-release potassium sulfate fertilizer and preparation method thereof |
| abstract | The invention belongs to the field of crop fertilizers, and in particular relates to a slow-release potassium sulfate fertilizer and a preparation method thereof. The preparation method of the slow-release potassium sulfate fertilizer mainly comprises the following steps: mixing and dissolving acrylic acid, acrylamide, a crosslinking agent and potassium sulfate, then adding an initiating agent to initiate free radical polymerization, then adding a load strengthening agent to form high-load slow-release potassium sulfate, then performing radiation treatment by using an NH3 plasma, and introducing amino groups for increasing the fertilizer efficiency of the fertilizer. Slow-release potassium sulfate disclosed by the invention has quick-acting and slow-release functions, a quick-acting part can be used for rapidly acting on crops and promoting the growth of the crops, and a slow-release part can perform slow release, so that the great loss of the potassium sulfate fertilizer in soil can be prevented, the utilization rate of the fertilizer can be improved, and the consumption of the fertilizer can be reduced. Meanwhile, the added amino groups can be used for increasing the fertilizer efficiency of the fertilizer, activating the roots of plants, promoting the absorption of crops to the fertilizer and improving the quality of products. The slow-release potassium sulfate fertilizer disclosed by the invention can be dissolved in water, is suitable for water-soluble fertilizers, is environment-friendly, cannot cause pollution, and has positive significance in promoting the increase of the crop yield. |
