Production of organic fertilizer from straws

Abstract

Production of biological organic fertilizer from straw is carried out by mixing straw with animal feces, magnesium sulfate, honey, strain and water, stocking fermenting at 10-35degree for 10-20 days, stirring at 1-3 days, fermenting to reach 2-8% water content and obtaining final product. It has low fermentation temperature, easy control and costs low.

Description

Technical field [0001] The invention relates to a process method for producing organic fertilizers using plant straws, such as rice straw, wheat straw, corn stalks, etc., as raw materials. Background technique [0002] At present, the main raw materials for the industrial production of organic fertilizers are peat, oil cakes and municipal waste. The origin and storage of peat and oil cake raw materials are restricted and cannot be promoted on a large scale. Using municipal waste as a raw material to produce organic fertilizers can not only purify the environment, but also produce organic fertilizers. It is a good thing to kill two birds with one stone. However, the organic fertilizer produced from municipal waste has low organic matter concentration and unsatisfactory fertilizer efficiency. [0003] The use of straw, especially the use of crop straw, currently mainly uses burned plant ash as fertilizer to return to the field. This method is simple, but all its organic matter is b...

This method is simple, but all its organic matter is burned and wasted

According to literature reports, the technology of producing organic chemical fertilizers by straw fermentation abroad has a long fermentation time, up to more than 50 days, and the conversion rate of organic matter is low because there is no effective method for breaking the protective film on the straw surface that affects biological fermentation. , and the fertilizer efficiency is not ideal, thus restricting the promotion of organic fertilizers produced by straw

[0004] Chinese patent application No. 97107600.6 discloses a method of utilizing stalks to produce bio-organic fertilizers. The method adopts diamine carbonate as a breaking agent for the surface film of stalks. Although it has a certain effect, due to the addition of diamine carbonates, the , the fermentation temperature must be above 100°C, the fermented product is easy to harden, the nutritional content is not easy to control, and the production cost will increase significantly, so it is not suitable for popularization and use.
