Organic-inorganic compound fertilizer and preparing method thereof

Abstract

The invention discloses an organic-inorganic compound fertilizer and a preparing method thereof. The organic-inorganic compound fertilizer is prepared from, by weight, 50-60 parts of decomposed pig manure, 15-20 parts of urea, 20-25 parts of plant straw powder, 5-8 parts of furfural residues, 1-3 parts of zinc sulfate powder, 4-6 parts of sodium tripolyphosphate, 2-3 parts of ferrous sulfate, 4-5 parts of sodium carboxymethylcellulose, 10-15 parts of light calcium carbonate powder, 6-10 parts of potassium fulvic acid powder, 1-2 parts of ammonium molybdate, 2-4 parts of zinc sulfate, 1-3 parts of boron sulfate and 0.6-0.8 parts of ammonium molybdate. The organic-inorganic compound fertilizer is rich in nutrition and can fully meet the requirements of crops in the whole growth process; microelements including nitrogen, phosphorus, potassium and humic acid which exist in the fertilizer and are necessary for plants can regulate the growth of plants; meanwhile, raw materials are recycled into wealth, the environment is improved, and sustainable development of agriculture is promoted.

Description

technical field [0001] The invention relates to an organic-inorganic compound fertilizer and a preparation method thereof, belonging to the technical field of fertilizer processing. Background technique [0002] In order to develop ecological agriculture and develop and produce pollution-free "green food", the fertilization technology in agricultural production must be reformed, that is, the rational application of chemical fertilizers or precise fertilization, and the development of combined organic and inorganic fertilizers. Organic fertilizers are traditional farm fertilizers in our country. , is almost the only source of supplementing soil nutrients. Traditional organic fertilizers have problems such as "dirty smell, bitterness, and low efficiency" in the process of composting, preparation, transportation, and application. Bio-organic fertilizers refer to the combination of specific functional microorganisms and mainly animal and plant residues. Bio-organic fertilizer ...

Problems solved by technology

[0002] In order to develop ecological agriculture and develop and produce pollution-free "green food", the fertilization technology in agricultural production must be reformed, that is, the rational application of chemical fertilizers or precise fertilization, and the development of combined organic and inorganic fertilizers. Organic fertilizers are traditional farm fertilizers in our country. , is almost the only source of supplementing soil nutrients. Traditional organic fertilizers have problems such as "dirty smell, bitterness, and low efficiency" in the process of composting, preparation, transportation, and application. Bio-organic fertilizers refer to the combination of specific functional microorganisms and mainly animal and plant residues. Bio-organic fertilizer is a kind of fertilizer with both microbial fertilizer and organic fertilizer effects, which is composed of harmless and decomposed organic materials as the source. Bio-organic fertilizer has complete nutrients and can improve soil and improve soil compaction caused by the use of chemical fertilizers. Improve soil physical and chemical properties, enhance soil water retention, fertilizer retention, and fertilizer supply capabilities, and realize industrial production, solving the problems of "dirty, smelly, tired, and low efficiency" in traditional organic fertilizers
