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 performing spraying granulation. The method comprises the following steps of: preparing a solid inoculant; granulating a lignin waste liquor into organic granules; compounding the organic granules with solid powder, wherein a powdery inoculant is added in an amount of 5-15 percent by weight based on the total weight of a finished compound microbial fertilizer; and mixing, granulating and drying under the condition that the material temperature in a drying barrel is not higher than 80 DEG C. In the invention, a new path is opened, the convection is broken, a production method of the granular bio-organic fertilizer is partitioned into an organic granule granulating step and an organic granule coating step, a certain viable count in the bio-organic fertilizer is ensured simultaneously, breakthrough of the bio-organic fertilizer product from powdery and disc-drum granulation to a spraying granulation process is realized, and foundations are laid for enhancing the commodity, effectiveness and area popularization of the bio-organic fertilizer.
