Organic fertilizer and preparation method thereof

Abstract

The invention discloses an organic fertilizer and a preparation method thereof. The side end of a transmission connecting rod is connected with a material turning auger in a welded mode, one end of the transmission connecting rod is provided with a water inlet hole, the inner side of the water inlet hole is connected with a water inlet pipe in a sleeved mode, and the air inlet end of an air conveying pipe is installed at one end of an air collecting box in a penetrating mode; a gear transmission box drives a material overturning auger to overturn fermented raw materials, the raw materials and zymophyte materials can be mixed more evenly through material overturning in the early stage of fermentation, the situation that internal combustion coking occurs in the bottom end due to the fact that the fermentation temperature is too high is avoided, air is conveyed to the inner side of a fixed heat preservation box after being dried through a drying net box through an air inlet pipe, and water is discharged into a water inlet hole in the inner side of the transmission connecting rod through the water inlet pipe; the temperature, humidity and oxygen degree of the internal environment can be effectively controlled through interstitial treatment in the fermentation process, so that the treatment can be stably carried out in the fermentation process;.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to an organic fertilizer and a preparation method thereof. Background technique [0002] Organic fertilizer refers to a type of fertilizer that contains organic substances, which can not only provide a variety of inorganic and organic nutrients for crops, but also fertilize and improve the soil. There are only a small portion of commercial fertilizers. Fully and rational use of organic fertilizers can increase crop yields, improve soil fertility, improve the quality of agricultural products, and increase the effectiveness of soil nutrients. At present, organic fertilizers are generally produced by mixing residues and manure for fermentation. [0003] However, at present, when fermenting in the open air, it is necessary for the staff to turn over the fermented material at intervals. At the same time, it is inconvenient to control the humidity, temperature and oxygen. At t...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides an organic fertilizer and a preparation method thereof, which can effectively solve the above-mentioned background technology. At present, during open-air fermentation, workers need to turn over the fermented material at intervals. At the same time, it is inconvenient to control humidity, temperature and oxygen. At the same time, Germs in the external environment can easily affect the normal fermentation of fermentation strains, resulting in a decrease in fermentation efficiency and affecting the effect of fermentation
