Method for preparing special composite microbial fertilizer for non-deciduous fruit trees and capable of improving soil, and prepared product

Abstract

The invention discloses a method for preparing a special composite microbial fertilizer for non-deciduous fruit trees and capable of improving soil, and a prepared product. The preparation method comprises the following steps of: deodorizing fresh chicken manure and dairy cow manure; adding sporotrichum thermophile, aspergillus niger, brown sugar, crushed straws, vinasse and monopotassium phosphate, fermenting and performing air drying to obtain a preparation I; fermenting bean pulp, wheat bran, calcium powder, brown sugar, bacillus megatherium, bacillus subtilis, lactic acid bacteria and ferrous sulfate, and performing air drying to obtain a preparation II; and mixing the preparation I and the preparation II, adding bacillus megatherium, bacillus subtilis, aspergillus niger, streptomycete, terricolous cyanobacteria, photosynthetic bacteria and dinoflagellate, fermenting, and adding chemical fertilizers needed for growth of the non-deciduous fruit trees to obtain the special composite microbial fertilizer for the non-deciduous fruit trees. The prepared product contains viable beneficial microorganisms, and can be used for improving soil aggregated structure and other indexes, and increasing the yield of fruits.

Description

Technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a method for preparing soil-improving non-deciduous fruit tree special 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 farming households in rural areas. While the growth of farming households, farming manure 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, and calcium in caged layer manure, which have a 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 gas and cause serious pollution. The traditional method of manure treatment 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.

Different stages of fruit tree growth have different nutritional needs, especially non-deciduous fruit trees, and currently there is no all the nutrients required for the growth of non-deciduous fruit trees at each stage
