| titleOfInvention | Slow release compound fertilizer applicable to plantation of wheat |
| abstract | The invention provides a slow release compound fertilizer applicable to plantation of wheat. The slow release compound fertilizer is a mixture of a plurality of fertilizers and components with no special fertilizer efficiency. The slow release compound fertilizer applicable to plantation of wheat uses compound fertilizer as the core of fertilizer and is prepared by filming and dusting powder processing; and the slow release compound fertilizer is prepared from the following raw materials by mass: 21 to 47 parts of urea, 8 to 15 parts of ammonium sulfate, 10 to 30 parts of potassium sulfate, 20 to 35 parts of a mixed phosphate fertilizer, 0.1 to 0.5 part of an iron, manganese, boron, copper, zinc and molybdenum additive, 6 to 12 parts of a granulating auxiliary agent and a proper amount of water. A preparation method for the slow release compound fertilizer comprises the following steps: (1) preparation of a compound of a potash fertilizer and a nitrogen fertilizer; (2) preparation of the mixed phosphate fertilizer; (3) preparation of mixed particles of the components of the compound fertilizer; (4) coating with stearic acid; (5) powder spreading of a modified zeolite powder material; and (6) screening, metering, quality inspection and packaging. The slow release compound fertilizer applicable to plantation of wheat provided by the invention has overall nutrients and excellent slow releasing performance, improves both output and quality of wheat, saves resources and protects the environment. |
