| titleOfInvention | Slow release compound fertilizer applicable to plantation of tobacco |
| abstract | The invention provides a slow release compound fertilizer applicable to plantation of tobacco. The slow release compound fertilizer is a mixture of a plurality of fertilizers containing substances which exert influence on nitrification of urea in soil and components with no special fertilizer efficiency and is prepared by taking compound fertilizer particles as the fertilizer core, then performing coating and dusting powder treatment. The compound fertilizer particles are prepared from the following raw materials by mass: 20 to 45 parts of urea, 10 to 20 parts of ammonium sulfate, 20 to 40 parts of potassium sulfate, 10 to 30 parts of a mixed phosphate fertilizer, 0.1 to 0.5 part of a zinc, copper, boron 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 the compound fertilizer particles; (4) coating with stearic acid; (5) powder spreading of a modified zeolite powder material; and (6) screening. The invention provides the slow release compound fertilizer applicable to plantation of tobacco which has overall nutrients and excellent slow releasing performance, not only enables a high fertilizer utilization rate to be obtained, but also improves both output and quality of tobacco. |
