Bio organic fertilizer refers to a kind of fertilizer with both microbial fertilizer and organic fertilizer effect, which is composed of specific functional microorganisms and organic materials mainly derived from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and has been treated harmless and decomposed.
There are many raw materials for the production of bio organic fertilizer, which can be divided into the following categories:
Agricultural waste
Such as straw, soybean meal, cotton meal, rapeseed cake and so on.
Manure of livestock and poultry
Such as chicken manure, cattle, sheep and horse manure, rabbit manure;
Industrial waste
Such as wine lees, vinegar lees, cassava residue, sugar residue, furfural residue, sawdust, etc.;
Household garbage
Such as kitchen waste, vegetable market, etc.;
Municipal sludge
Such as river silt, sewage sludge and so on.
Plant product
Such as bamboo powder, bamboo charcoal, bamboo ash, straw charcoal, grass and wood ash.
Production technology
The production process of bio organic fertilizer is mainly the production process of organic fertilizer from raw materials to semi-finished products.
The main production process has two, one is the plane strip composting process, the other is the trough aerobic fermentation process. In addition, the laboratory small-scale trial production also uses sealed box/tank fermentation.
1. Plane strip composting technology.
Production process: raw material treatment -- add bacteria -- mix -- build stomp -- turn over pile -- add bacteria twice -- mix -- test -- packaging -- leave the factory
Advantages: small investment, relatively simple process
Disadvantages: covers a large area, not thoroughly decomposed, serious secondary pollution.
2. Trough aerobic fermentation process.
Production process: raw material treatment -- adding bacteria -- mixing -- into the tank -- turning over the pile -- adding bacteria twice -- mixing -- inspection -- packaging -- leaving the factory
Advantages: thoroughly decomposed, high product quality, small secondary pollution
Disadvantages: equipment investment is large
