An organic compound fertilizer and a preparation method thereof

Abstract

The invention discloses an organic compound fertilizer. The fertilizer is prepared from following raw materials in parts by weight: 20-30 of livestock manure, 10-14 of bone meal, 20-25 of gangue, 9-12 of oyster shell powder, 15-18 of coal slime, 20-22 of coal ash, 10-12 of urea, 15-18 of potassium dihydrogen phosphate, 20-24 of potassium chloride, 3-5 of zinc sulfate, 2-3 of ammonium molybdate, 9-12 of ammonium nitrate, 6-9 of ammonium bicarbonate, 3-5 of borax and 9-12 of a soil conditioner. The livestock manure, the bone meal, the gangue, the oyster shell powder, the coal slime, the coal ash, and other natural raw materials are adopted by the organic compound fertilizer. The raw materials are convenient to take and low in cost, and therefore the production cost is largely reduced and the organic compound fertilizer is prone to popularization in fertilizer production. In addition, the fertilizer is rich in nutrition and can improve the soil structure. The oyster shell powder contains a large amount of calcium carbonate, and essential trace elements comprising copper, magnesium, potassium, molybdenum, phosphor, manganese, iron, zinc, and the like for animals. The pearl powder layer of the oyster shell contains a plurality of amino acid components. The oyster shell powder can provide rich nutrients for the fertilizer. The coal ash is one of the industrial residues with large discharge amount at present in China. The coal ash is in a porous honeycomb structure and has large specific surface area, high absorptivity and strong water absorptivity.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an organic compound fertilizer and a preparation method thereof. Background technique [0002] Nowadays, the main fertilizers used in my country are still chemical fertilizers, which have the advantages of high nutrient content, fast fertilizer efficiency, easy preservation, and abundant production raw materials. However, chemical fertilizers also have certain disadvantages, such as insufficient nutrients and certain limitations on soil and crops. Moreover, the absorption rate of fertilizers is generally very low, so that the residual chemical fertilizers will cause compaction of the soil, and even cause pollution to the environment. In fact, the utilization rate of organic compound fertilizer is relatively high, and it is not easy to cause soil compaction and other phenomena, and its use is environmentally friendly. However, due to the high cost of production, it has not b...
