Preparation method for composite microorganism fertilizer specially used for improving soil for vegetables and composite microorganism fertilizer

Abstract

The invention discloses a preparation method for a composite microorganism fertilizer specially used for improving the soil for vegetables and the composite microorganism fertilizer. The preparation method comprises the following steps of: deodorizing fresh chicken manure and fresh cow dung, adding thermophilic side mold, aspergillus niger, red sugar, smashed straws, vinasse, corn powder and monopotassium phosphate for secondary fermentation, and performing air drying to obtain a preparation I; performing secondary fermentation on bean pulp, wheat bran, calcium powder, red sugar, bacillus megatherium, bacillus subtilis, lactic acid bacteria and ferrous sulfate, and then performing air drying to obtain a preparation II; and mixing the preparation I and the preparation II, then adding the bacillus megatherium, the aspergillus niger, streptomycete, terrestrial cyanobacteria, photosynthetic bacteria and dinoflagellate for fermentation, and finally adding chemical fertilizers required by growth of vegetables to obtain the composite microorganism fertilizer specially used for the vegetables. The obtained product contains survival beneficial microorganisms and can improve the particle structure and other indexes of the soil and improve the yield of the vegetables.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a method for preparing soil-improving vegetable-specific compound microbial fertilizer, 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 co...

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.

Vegetables have different nutritional requirements at different growth stages, among which the absorption of nitrogen is the largest, and the existing chemical fertilizers and organic fertilizers cannot well meet the nutritional needs of vegetables at different stages.
