Biological rhzomorph organic fertilizer based on compound microorganism fermented caged chicken manure and preparation method of biological rhzomorph organic fertilizer

Abstract

The invention discloses a biological rhzomorph organic fertilizer based on compound microorganism fermented caged chicken manure and a preparation method thereof. The biological rhzomorph organic fertilizer is prepared from the following raw materials in percentage by weight: (70% of dry basis) caged chicken manure (15% of edible mushroom residue), (18% of zeolite powder), composite flora (1% of photosynthetic bacteria, 1% of EM bacteria, 1% of bacillus, 1% of nitrobacteria and (1% of molasses), process characteristics (composting fermentation, zeolite powder modification and sunlight exposure) and product application (biological rhzomorph organic fertilizer).

Description

[0001] This invention relates to the field of microbial fertilizer technology, and in particular to a high-efficiency bio-organic fertilizer that utilizes a composite microbial community to synergistically ferment caged chicken manure, combined with edible mushroom residue and zeolite powder modification. Background Technology

[0002] The shortcomings of existing chicken manure organic fertilizer:

[0003] Traditional composting methods often result in incomplete decomposition (easily producing ammonia and pathogen residues).

[0004] The fermentation rate of a single strain is low (for example, it is difficult to simultaneously degrade cellulose and fix nitrogen using only Bacillus).

[0005] Heavy metal / antibiotic risks (copper and zinc exceeding standards are commonly found in caged chicken manure).

[0006] The shortcomings of existing technologies: They fail to address the synergistic issues of microbial interactions, carrier-level adsorption, and nutrient slow release. Summary of the Invention

[0007] Innovation points:

[0008] Microbial community compatibility design:

[0009] Photosynthetic bacteria (using H2S / NH3 in chicken manure as electron donors)

[0010] Bacillus (secretes cellulase to degrade lignin in bacterial residue)

[0011] .EM bacteria (maintain pH stability in the fermentation system)

[0012] Nitrifying bacteria (reduce nitrogen loss through volatilization)

[0013] Carrier synergistic effect:

[0014] The porous structure of mushroom residue promotes microbial colonization.

[0015] Zeolite powder adsorbs heavy metals and slowly releases potassium / ammonium ions.

[0016] Technical effect

[0017] Fermentation cycle shortened by 40% (compared to single-strain fermentation).

[0018] The passivation rate of heavy metals Cd / Pb in the finished fertilizer is ≥70%.

[0019] After application, available nitrogen in the soil increased by 35%, and tomato yield increased by 22% (example data). Detailed Implementation

[0020] Detailed technical solution:

[0021] Raw material pretreatment: Edible mushroom residue is crushed to 2-5mm, and chicken manure is used to adjust the moisture content to 50-60%.

[0022] Raw material ratio: caged chicken manure (70% dry basis), shiitake mushroom residue (15%), zeolite powder (8%), compound microbial agent (3% of the inoculum in a 1:1:1:1 ratio), molasses (1%)

[0023] Fermentation process:

[0024] Adjust the moisture content of the mixture to 50-60%, with a C / N ratio of 28:1.

[0025] Aerobic fermentation at 0.55°C for 5 days, with the pile turned 4 times.

[0026] The compost should be leveled on the ground and exposed to sunlight until the moisture content is less than 15%.

[0027] Organic fertilizer can be made into granules (2-4 mm in diameter) or powder.

[0028] Performance testing: Provide product performance testing data (as shown in the example table below) and field trial results.
