Corn stalk carbonization production organic fertilizer

Abstract

The invention discloses a corn straw carbonization production organic fertilizer, which comprises the following raw materials in parts by weight: wherein, the main raw materials are corn straw charcoal, mixed sheep manure, a fermentation agent, an adhesive and a forming auxiliary agent; the ingredients are wood acetic acid liquid; According to the invention, the corn straw and the sheep manure aremixed, the utilization rate of the fertilizer is improved through the characteristics of adsorption and slow release, the utilization rate of the fertilizer is improved, and the soil improvement function and the fertilizer efficiency are balanced; The method comprehensively utilizes the recovery of nitrogen and phosphorus elements in the corn straw carbon and the sewage and does not discharge waste water, waste liquid and waste residues in the production, and all indexes meet the industry standard of the organic fertilizer; Compared with the prior art, the invention is characterized by reducing planting component, improving the economic benefit, and giving consideration to both soil improvement function and fertilizer synergistic effect.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to an organic fertilizer produced by carbonizing corn stalks. Background technique [0002] Straw is a valuable biological resource. Corn stalks are a high-quality fertilizer source with a large quantity, a wide source, and can be used locally. It contains a variety of nutrients needed by plants. Corn stalks contain 57.815% of crude organic matter, 1.107% of total nitrogen, and 0.355% of total phosphorus. %, total potassium 0.645%, calcium 1.731%, magnesium 0.588%, copper 24.565mg / kg, zinc 67.714mg / kg, iron 11497.863mg / kg, manganese 219.216mg / kg, boron 13.305mg / kg, molybdenum 0.517mg / kg , sulfur 0.25mg / kg and other organic matter and various nutrients. After the corn straw is returned to the field, it slowly decomposes in the soil through the action of microorganisms, releasing the mineral nutrients in it for absorption and utilization by the crops; the organic matter ...

Problems solved by technology

[0003] At present, the main method of returning corn stalks to the field is direct straw returning, but corn stalks are mainly composed of cellulose and hemicellulose, which are difficult to use for crops, and there are also problems such as affecting the emergence of sowing seedlings, and the straw is easy to carry bacteria.

The conversion effect of indirect return to field methods such as composting is also poor, and there are still many problems in fertilizer utilization.
