Abstract

The invention relates to an organic-inorganic compound fertilizer and a preparation method thereof. The organic-inorganic compound fertilizer comprises the following compounding raw materials in partsby weight: 500 to 720 parts of high-temperature pyrolysis lignite powder, 140 to 200 parts of lignite fly ash, 55 to 110 parts of urea, 55 to 70 parts of potassium nitrate, 35 to 55 parts of potassium sulfate, 115 to 130 parts of monoammonium phosphate and 100 to 130 parts of monopotassium phosphate. The method has the beneficial effects that the high-temperature pyrolysis lignite powder and thelignite fly ash can kill harmful ingredients such as roundworm eggs and fecal coliform, the high-temperature pyrolysis lignite powder is obtained after lignite is insufficiently combusted in the absence of oxygen, and the production process is simple; the lignite power plant fly ash waste is directly used as a fertilizer raw material, the waste is effectively utilized, the organic-inorganic compound fertilizer obtained by compounding can have the fertilizer nutrients fully absorbed by crops, and the utilization rate of the fertilizer is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to an organic-inorganic compound fertilizer and a preparation method thereof. Background technique [0002] Organic-inorganic compound fertilizer is a kind of compound fertilizer that contains both organic matter and appropriate amount of chemical fertilizers. Usually, organic materials such as animal manure and straw are treated harmlessly and effectively through microbial fermentation, and appropriate amount of chemical fertilizers and humus are added. Acid, amino acid or beneficial microbial bacteria, the commercial fertilizer made by granulation or direct blending, has the dual characteristics of organic fertilizer and inorganic fertilizer. The proper proportion of organic components can make the organic-inorganic compound fertilizer have a suitable fertilizer supply intensity and can last for a long time. At present, inorganic compound fertilizers are mostly u...
