Problems solved by technology

However, at present, these artificially added bacterial agents are either too specific and only have obvious effects on a single type of waste; or lack of pertinence, different compost raw materials use the same preparation, after inoculating different compost raw materials, The microbial community in the fermentation agent needs structural self-regulation during the composting process, which will lose a lot of beneficial microbial resources and reduce the fermentation efficiency

Embodiment 1

[0054] Embodiment 1: the preparation of ternary microbial compound bacterial agent

[0055] Bacillus, actinomycetes, yeast, lactic acid bacteria, Trichoderma, Aspergillus, Penicillium, white rot fungus, photosynthetic bacteria, nitrogen-fixing bacteria, phosphate-solubilizing bacteria and silicon Salt bacteria species, on the corresponding culture medium, the slant activation culture and liquid expansion culture were carried out as usual.

[0056] The slant activation medium used includes PDA medium, nutrient agar medium, Ashubei medium, RCVBN medium, MRS medium, etc.;

[0057] The liquid expansion medium used includes PDA medium (for cultivating molds and yeasts), broth medium (for cultivating bacteria), Gaoshi No. 1 medium (for cultivating actinomycetes), No. 77 nitrogen-fixing medium (for cultivating nitrogen-fixing bacteria), RCVBN medium (for cultivating photosynthetic bacteria), MRS medium (for cultivating lactic acid bacteria), etc.

[0058] After the liquid expansion...

Embodiment 2

[0074] Take compound bacterial agent I 30-60%

[0075] Compound bacterial agent II 30~60%

[0076] Composite bacterial agent III is mixed at a ratio of 10-20% to obtain a ternary microbial composite bacterial agent.

[0077] The organic waste raw material that is made of chicken manure 30% (weight percentage) and wheat straw 70% (weight percentage) is stacked in strip form, and the moisture is controlled at 60% in the early stage of fermentation. 1-10% of the above-mentioned ternary microbial compound bacterial agent is directly added, mixed evenly with the composting material, and then composted. During the composting process, the changes in air temperature and compost temperature are recorded every day, and the compost is properly turned according to different temperature rises to maintain a good fermentation state. After fermentation, it is processed into organic fertilizer or microbial organic fertilizer.

[0078] When adding 3% starter formulatio...

Embodiment 3

[0088] The organic waste raw material composed of 80% (weight percentage) of cow dung from dairy farms and 20% (weight percentage) of wheat straw is piled up in strips, and the moisture content is controlled at 60% in the initial stage of fermentation. According to the ratio of 30 parts of compound bacterial agent I, 50 parts of compound microbial agent II and 20 parts of compound bacterial agent III, the ternary microbial compound bacterial agent is used.

[0089] The addition of the ternary microbial compound bacterial agent is carried out in three ways:

[0090] 1# treatment - add 5% of the total amount of composting raw materials at the initial stage of composting, and add the ternary microbial compound bacterial agent at one time, and mix it evenly with the composting material before composting.

[0091] 2# treatment——according to 5% of the total weight of the composting raw materials, add the ternary microbial compound bacterial agent twice: at the initial stage of compo...

Abstract

A composite biological agent with ternary microorganism for composting process of agricultural waste is composed of a composite biological agent I, a composite biological agent II, and a composite biological agent III, which is characterized in that the composite biological agent I is composed of bacillus, actinomycetes, microzyme and lactobacillus, the composite biological agent II is composed of trichoderma, ergillus, penicillium and trametes versicolor, and the composite biological agent III is composed of photosynthetic bacterium, azotobacter, phosphorus bacteria, and silicate bacterium. 30-60% composite biological agent I, 30-60% composite biological agent II, 10-20% composite biological agent III are mixed or applied to the process of composting process of agricultural waste in phases. Each component ratio and recruitment of biological agents can be both properly adjusted with different dung materials and dung purpose, thereby achieving purpose of using microorganism resources efficiently and raising fermentation efficiency.

Description

1. Technical field [0001] The invention belongs to the technical field of using microbial fermentation to produce natural fertilizers, and in particular relates to a ternary microbial compound bacterial agent used for composting and fermenting agricultural organic waste and its application in composting. 2. Background technology [0002] my country is a large agricultural country, which produces about 5 billion tons of agricultural waste every year, including livestock and poultry manure, crop stalks, township domestic waste, processing industry waste, etc. The random discarding of these organic wastes not only causes serious environmental problems, It is also a huge waste of resources. Aerobic composting is an important means to realize the recycling and harmless treatment of agricultural waste and alleviate agricultural pollution, and it is also one of the effective ways to promote sustainable agricultural development. [0003] The traditional composting method is complete...
