Production process of biological-organic-inorganic ternary compound fertilizer

Abstract

The invention provides a production process of a biological-organic-inorganic ternary compound fertilizer which is prepared by the following steps: mixing crop stalks, such organic components as livestock manures and active biological agents, regulating the carbon nitrogen ratio from 26 to 35, PH from 5.5-8.2 and moisture from 40% to 65% according to the organic matter contents of the crop stalksand the livestock manures, fermenting the mixture at minus15-75 DEG C for 20-50 days and ensuring the living bacteria count to be 0.03-0.2 billion / g, carrying out turning and oxygenating, fermenting in deep tanks and grinding on the mixture to prepare the biological organic fertilizers, mixing the biological organic fertilizers with the inorganic fertilizers and trace elements and simultaneously adopting the low-temperature drying process after extruding granulation and the biological agent spraying and cooling technology. The method can greatly shorten the decay period, ensure little nutrientloss and little generating capacity of sour gases in the processes of fermentation and decay and complete decay and fermentation, can enhance the stress resistance of the crops, ensure obvious disease-resistant effects and high survival rates of specific functional bacteria and has wide application. Through field contrast tests, both the production and income are increased by 10-25% by applying the biological organic fertilizer.

Description

technical field [0001] The invention relates to a production process of bio-organic-inorganic ternary compound fertilizer, especially to produce bio-organic-inorganic compound fertilizer by turning and throwing fermentation, granulation technology and bacterial agent spraying technology by using livestock and poultry manure, crop straw organic matter, biological bacterial agent and inorganic fertilizer The production process of compound fertilizer. Background technique [0002] There are many bio-organic fertilizer production methods at home and abroad. The industrialization of bio-fertilizer in my country started late, with few manufacturers, small scale, backward equipment and technology, low output and poor quality, which are far from meeting the development needs of pollution-free green and organic agriculture. The technology of producing bio-organic fertilizer by fermenting livestock and poultry manure is a new biological treatment technology developed rapidly in the wo...

Problems solved by technology

The main disadvantages of the strip stacking process are: the strip stack is too large to form an anaerobic zone near the center, and sour and smelly gas is released when the strip stack is turned over; Pathogens such as coliform bacteria, less water evaporation

Compared with the stack type, the fermentation cycle is shorter, the fermentation quality is improved, and the labor intensity is reduced, but its scale is small, the equipment is severely corroded and worn, and the operating cost is high

Whether it is strip-stack or traditional tank-type fermentation, there is a general confusion of bacterial species, lack of standardized process and technical parameters, unreasonable equipment structure and other factors, resulting in unstable microbial counts in the production process, especially in the high-temperature drying process. In the process, a considerable part of the functional bacteria in the original biological bacteria was inactivated and died, resulting in unstable product quality and ineffective use
