Abstract

The invention relates to an ore slow release compound fertilizer which comprises the following ingredients in parts by weight: 60 to 80 parts of coal ash, 3 to 8 parts of iron tailing ore, and 30 to 40 parts of a compound fertilizer. The invention further relates to a preparation method of the ore slow release compound fertilizer. The preparation method comprises the following steps: crushing the 60 to 80 parts of coal ash and the 3 to 8 parts of iron tailing ore into powder by a crusher, and magnetizing the powder in a magnetic field; adding the magnetized powder into water and performing stirring; granulating the 30 to 40 parts of the compound fertilizer; spraying the stirred liquid onto the compound fertilizer granules, coating the compound fertilizer granules, and drying the coated compound fertilizer granules to obtain the ore slow release compound fertilizer. The ore slow release compound fertilizer and the preparation method have the advantages that the process is simple; the production period is short; the raw materials are wide in source; the equipment requirement is low.

Description

technical field [0001] The invention relates to a fertilizer, in particular to an ore sand slow-release compound fertilizer and a preparation method thereof. Background technique [0002] At present, the known compound fertilizer is in a kind of chemical fertilizer, contains two or more fertilizers in the three elements of nitrogen, phosphorus and potassium. Compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. Compound fertilizer has a long fertilizer effect and should be used as base fertilizer. It decomposes slowly. For crops that use compound fertilizer as base fertilizer during sowing, due to the law of fertilizer demand of different crops, it is necessary to supplement available nitrogen fertilizer in time when topdressing to meet the nutritional needs of crops. However, long-term field experiments and research results show that the nutrient ratio of compound fertilizers is always fixed, while the type...
