Organic fertilizer production process for treating straws by acid and alkali

Abstract

The invention provides an organic fertilizer production process for treating straws by acid and alkali. The organic fertilizer is prepared sequentially by virtue of alkali treatment, acid treatment, neutralization treatment, biological bacterium solution mixing, stacking for fermenting and fertilizer turning. According to the production process, the straws are sequentially subjected to alkali treatment and acid treatment, then a biological bacterium solution is added, the straws and the biological bacterium solution are mixed for fermentation so as to prepare the organic fertilizer; the straws are treated by alkali and acid solutions, and most of cell walls of the straws can be damaged, so that bacterial colonies of the biological bacterium solution can be rapidly formed on the straws and wheat bran. By virtue of the method, the organic fertilizer production time is greatly shortened; the biological bacterium solution adopted in the production process is capable of thoroughly decomposing and converting protein, starch, fat, cellulose and lignin in an organic matter into micromolecule substances which are easy to absorb and utilize, and beneficial microorganisms and metabolites thereof are capable of decomposing harmful substances with putrid odor, such as ammonia, amine salt, sulfide and phenols, so that no odor is generated in the preparation process. After the organic fertilizer is utilized, the total crop yield is improved.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to an organic fertilizer production process for treating straw with acid and alkali. Background technique [0002] Organic fertilizers are mainly derived from plants and (or) animals. They are applied to the soil to provide plant nutrition as carbon-containing materials. They are processed from biomass, animal and plant waste, and plant residues to eliminate toxic and harmful substances. Substances, rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium, not only can provide comprehensive nutrition for crops, but also have a long fertilizer effect, which can increase and update soil organic matter , promote the reproduction of microorganisms, improve the physical and chemical properties and biological activity of the soil, and are the main nutrients for green food produc...

Problems solved by technology

[0004] After the current chemical fertilizers are applied, it is easy to cause soil compaction, soil fertility decline and environmental pollution.

The long-term use of these chemicals leads to the variation of the physical and chemical properties of the soil used, the accumulation of harmful residues of ammonia nitrogen and its chemical components in the soil water system, which leads to soil pollution, degradation and compaction, and also brings harm to the surrounding environment. greater pollution
