Problems solved by technology

[0005] One is organic raw materials: there are some round-grain bio-organic fertilizer products on the market, but humic acid (humic acid) is basically used as the organic carrier for granulation. Other organic raw materials such as poultry manure, straw, etc. There are many wood fibers, light specific gravity, insufficient viscosity and fineness, so it is difficult to form pellets. They are mainly extruded and granulated columnar products, but columnar products cannot be sown by machine.
In addition, humic acid is a mineral with limited resources. Extensive mining will destroy the ecology, and it is difficult to dissolve in the soil. The organic matter and humic acid in it are difficult to be used by crops, which affects fertilizer efficiency. At the same time, the price of humic acid is increasing year by year. Rising, the production cost of the product is also increasing year by year
Livestock and poultry manure is difficult to carry out large-scale mass production due to its slow fermentation and maturity, heavy air pollution, large space occupation, and time-consuming. After being applied to the soil, if it is not fully decomposed, it will cause burnt seedlings, and because of poultry manure There are a lot of harmful bacteria such as Escherichia coli and roundworm eggs, and long-term application of organic granules produced by poultry manure will increase soil diseases
[0006] The second is the impact of granulation and drying on live microorganisms: the process of granulating bio-organic fertilizers is mainly disc granulation or drum granulation. After granulation, it must be dried in a drying cylinder. The living microorganisms are killed, so the granulation of bio-organic fertilizer is restricted
[0007] The third is difficult to dissolve: using humic acid as an organic carrier to produce round bio-organic fertilizers has another problem that it is difficult to dissolve. Since humic acid is a mineral, the fertilizer particles are very strong after granulation and drying, and it is applied to the soil. It is difficult to absorb water and dissolve in it, and the organic matter and humic acid contained in it are difficult to be used by soil and crops, which will affect the product effect and have a great impact on the marketing of the product
[0008] Due to the above reasons, the granulation of bio-organic fertilizer will affect the quality and effect of the product, thus causing difficulties in product promotion

Abstract

The invention provides a method for producing a bio-organic fertilizer by using lignin organic granules. The method provided by the invention comprises steps of: preparing a liquid inoculant, preparing a lignin black liquor into an organic particulate agent by spraying granulation, and compounding the organic granules and the liquid composite inoculant, wherein the liquid composite inoculant which accounts for 0.5-1.5% of the weight of the finished product composite microbial fertilizer is added. The production of the bio-organic fertilizer can be completed by bacterial liquid permeation intoorganic particles and the technical requirement of the product can be reached without drying. According to the invention, routines are broken by creative introduction of the spraying granulation method into the biological fertilizer granulation technology. The production method of the particulate bio-organic fertilizer is divided into two steps of spraying granulation of the organic granules and organic granule wrapping or inoculant adsorption. In the meanwhile, a certain activity of the bio-organic fertilizer is maintained. According to the bio-organic fertilizer product, the breakthrough from a powder form to spray particles is realized, thus laying a foundation for the extensive popularization of the bio-organic fertilizer.
