The development of biofertilizer project
can not only ensure the stable production and income increase of crops, but also do not damage the ecological environment and human health. It can achieve a virtuous cycle of social, economic and ecological benefits. The market potential is huge and the development prospect is very promising.
1. Production process
The production of bio organic fertilizer is mainly based on the production of microbial fertilizer. In the fermentation production process, the tank stacking fermentation method is mostly used. There are other fermentation methods, such as the flat stacking fermentation method, the fermentation tank fermentation method and the sealed warehouse fermentation method, which are also applied in the production. In the process of fermentation and ripening, the adjustment of material moisture, carbon nitrogen ratio, temperature and the use of ripening agent are the key to the production process, especially the application of bacterial agent directly affects the fermentation cycle and ripening degree of material. The decomposed material basically realizes the harmless of the product, which is also conducive to the survival of the functional bacteria added in the post-treatment process.
2. Production technology
In the post-treatment of fermentation materials, most enterprises add functional bacteria for compounding and shaping, the product dosage form is mainly dust, but there are also organic fertilizer machines
such as rotary drum granulator
or extrusion granulation, so the cost and benefit of making particles will be greater than dust. Particle products overcome the disadvantages of poor appearance and low level of powder products, improve the commodity of products, but also improve the production cost of enterprises, and have a certain impact on the survival of effective bacteria.
3. Bacteria addition in fertilizer production process
Microbial strains are the core of bio organic fertilizer products. In the fertilizer production process
, there are generally two links related to the use of microorganisms:
The first is to add the ripening bacteria agent which can promote the decomposition of materials and the function of deodorization in the process of ripening. It is mostly composed of complex bacteria, and the common bacteria are photosynthetic bacteria, lactic acid bacteria, yeast, actinomycete, Penicillium, Trichoderma, etc;
The second is the functional bacteria added after the material is mature, which are mainly nitrogen bacteria, phosphorus dissolving bacteria, silicate bacteria, lactic acid bacteria, Pseudomonas, actinomycetes, etc., and play a specific fertilizer effect in the product. Therefore, for the production of bio organic fertilizer, the screening and use of microbial strains is a core technology. Only by mastering this key technology can we speed up the decomposition and maturity of materials and ensure the application effect of products.
