Problems solved by technology

However, most of the nutrients in the discarded bacterial packs exist in the form of macromolecules, which are difficult to be directly absorbed and utilized by plants. This not only seriously affects the agricultural efficiency of the discarded bacterial packs, but also puts considerable pressure on the environment, causing pollution and affecting agriculture. sustainable development

Embodiment 1

[0020] A method for preparing bio-organic fertilizer, characterized in that the bio-organic fertilizer is made of edible fungus waste fungus residue, livestock manure (one or more of chicken manure, duck manure, pig manure, cow manure, etc.), Biomass such as distiller's grains is prepared by the following method:

[0021] (1) The Aspergillus niger isolated from the decaying wood and bamboo chips is cultivated with potato culture medium.

[0022] (2) Degradation of bacteria residue: crush the collected edible fungus residue to a particle size of ≤10mm, introduce the above-mentioned cultured Aspergillus niger into the crushed bacteria residue, and adjust the relative moisture content of the bacteria residue to 50%-70% with water , And then pile up 2-3 meters long, 1-1.5 meters wide, 1-1.5 meters high biomass pile, covered with plastic film and fermented for 15 days. The Aspergillus niger is a mixture of Aspergillus niger separated from decaying wood and bamboo, and the mixing ratio ...

Abstract

Bio-organic fertilizer is prepared from edible fungus waste residues, livestock excrement (one or more of chicken manure, duck manure, pig manure, cow manure and the like), distillers' grains and other biomass through mixing in a certain ratio. Firstly, the edible fungus waste residues are degraded by Aspergillus niger separated from decayed wood and bamboo chips, and then, the degraded edible fungus waste residues are mixed and composted with the livestock excrement (chicken manure, duck manure, pig manure, cow dung and the like), the distillers' grains, urea, calcium phosphate, biological bacterial fertilizer fermentation broth and the like for preparing the bio-organic fertilizer. Macromolecular substances in the fungus residues can be effectively degraded by the Aspergillus niger separated from the decayed wood and the bamboo chips, and accordingly, micromolecular nutrients are increased significantly, and growth and reproduction of microorganisms are facilitated.

Description

Technical field [0001] The invention relates to a biological organic fertilizer, in particular to a biological organic fertilizer and a preparation method thereof. Background technique [0002] Organic fertilizer is one of the traditional fertilizers in my country's agriculture. Relevant studies have shown that organic fertilizers contain a large amount of nutrients such as nitrogen, phosphorus, and potassium, as well as trace elements necessary for plant growth as growth regulators. Applying organic fertilizer to farmland soil can not only directly increase soil fertility, but also improve the physical and chemical properties of soil, promote plant growth, increase crop yield, and significantly improve the quality of agricultural products. Organic fertilizer is considered to be an essential fertilizer for the production of organic food. [0003] Edible fungus waste, also called fungus residue, fungus residue, scraps, etc., is the culture material after edible fungus cultivation....
