Biological organic fertilizer production process and technology

The technical content of biofertilizer project is relatively high. In addition to the biological bacterial agent that promotes the maturation and decomposition of organic materials during the maturation process, in order to achieve the purpose of targeted maturation and deodorization, it is necessary to add microorganism’s products with specific functions to enhance the effect of products. At present, in China, biological organic fertilizers are included in the scope of microbial fertilizers, and stricter management measures than organic fertilizers are implemented to promote the healthy development of organic fertilizers.
bio organic fertilizer production
1. The production process of bio-organic fertilizer production enterprises registered with the Ministry of Agriculture is basically engaged in the production of microbial fertilizers. In the fermentation production process, most of the tank stacks fermentation methods are used, as well as other fermentation methods, such as: the flat stacking fermentation method, the fermentation tank fermentation method. During the fermentation and maturation process, the adjustment of the moisture, carbon-nitrogen ratio, temperature, and etc. of the material and the use of the curing agent are production processes. The key is that the application of the fungicide directly affects the fermentation period and the degree of maturity of the materials. The maturing materials basically achieve the harmlessness of the product, which is also conducive to the survival of the functional bacteria added during the post-treatment process.

2. Production technology in terms of the post-treatment of fermented materials, most companies add functional bacteria for compounding and shaping. The product dosage form is mainly dust, but there also use drum type fertilizer granulator machine or roller press granulator for granulation. Granular products overcome powder products. The shortcomings of poor appearance and low level have improved the commerciality of the product, but at the same time it has also increased the production cost of the enterprise and had a certain impact on the survival of effective bacteria.

3. Bacterial species and the use of microbial strains is the core of biological organic fertilizer products. In the production process, there are generally two links related to the use of microorganisms:
The first is to add a decomposing fungicide that promotes the decomposition of materials and decomposes and deodorizes during the decomposing process. It is mostly composed of complex strains. Common species include photosynthetic bacteria, lactic acid bacteria, yeast, actinomycetes, penicillium, wood Fungi, etc .; the second is functional bacteria added after the material is decomposed, generally azotobacter, phosphorus-soluble bacteria, silicate bacteria, lactic acid bacteria, pseudomonas, actinomycetes, etc., to play a specific fertilizer in the product Therefore, for the production of biological organic fertilizer, the selection and use of microbial strains is a core technology, and only by mastering this key technology can we speed up the decomposition and maturation of materials and ensure the application effect of products.
