Preparation method of special compound microbial fertilizer for wheat for improving soil and product thereof

Abstract

The invention discloses a preparation method of a special compound microbial fertilizer for wheat for improving soil and a product thereof. The preparation method comprises the following steps of: first, deodorizing fresh chicken manure and dairy cattle manure, adding thermophilic sporotrichotic, aspergillus niger, brown sugar, crushed straws, flour and corn powder to ferment, then, adding potassium dihydrogen phosphate for continuous fermentation, and airing to obtain a preparation I; then, mixing bean pulp, wheat bran, calcium powder, brown sugar, bacillus megatherium, bacillus subtilis, lactic acid bacteria and ferrous sulfate to ferment, and airing to obtain a preparation II; then, mixing the preparations I and II, then, adding bacillus megatherium, aspergillus niger, lactic acid bacteria, streptomycete, terrestrial cyanobacteria, photosynthetic bacteria and dinoflagellate to ferment, and finally adding a chemical fertilizer required by wheat to obtain the special compound microbial fertilizer for wheat. The product produced contains viable beneficial microorganisms which can improve the granular structure and other indexes of soil, so that the output of wheat is improved.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a method for preparing soil-improving compound microbial fertilizer special for wheat, and also relates to a product prepared by the method. Background technique [0002] With the vigorous development of the tertiary industry in rural areas, there are more and more farmers in rural areas. While the number of farmers is increasing, the amount of manure raised is also increasing. It contains many nutrients that have not been digested and absorbed, such as crude fiber in ruminant manure, nitrogen in pig and chicken manure, calcium in caged laying hen manure, etc., which have great potential for utilization. If these feces are not treated in a timely and effective manner, they will seriously occupy and pollute the soil and water bodies, produce malodorous gases and cause serious pollution. The traditional manure treatment method is to use manure directly as fertilizer, but com...

AI Technical Summary

Problems solved by technology

If these feces are not treated in a timely and effective manner, they will seriously occupy and pollute the soil and water bodies, produce malodorous gases and cause serious pollution.

The traditional manure treatment method is to use manure directly as fertilizer, but complex organic matter and macromolecular compounds cannot pass through the cell wall and cell membrane of root hair cells; therefore, when organic fertilizer is applied to the soil, it is necessary to rely on soil microorganisms to decompose complex organic matter into simple components, or Ionization can be absorbed; such as nitrogen fertilizer must be converted into ammoniacal nitrogen (NH 4+ ) and nitrate nitrogen (NO 3- ), phosphate fertilizer must be converted into phosphate (PO4 3- ), potassium fertilizer must be converted into potassium ions (K + ) crops to absorb

The existing organic fertilizers mainly use microorganisms to decompose the macromolecules in the organic fertilizers into small molecules, but the beneficial microorganisms cannot continue to multiply after being applied to the soil, so it cannot fundamentally improve due to partial application, single application, and heavy application of chemical fertilizers. Leading to changes in soil pH, lower organic matter content, serious soil compaction, poor water retention, fertilizer retention, and poor air permeability, and reduction of beneficial biological flora in the soil, etc.

During the growth process of wheat, different stages have different nutritional requirements, and currently there is no all the nutrients required for the growth of wheat at each stage.
