Embodiment Construction

[0015] Using chicken manure as the main raw material, the fresh chicken manure is naturally dehydrated to a moisture content of 45%. Then add rice husk and humic acid according to the mass ratio of dehydrated chicken manure, rice husk and humic acid at 70:20:10. Add KH according to 0.5% of the weight of dehydrated chicken manure 2 PO 4 as a P source. According to 1% of the total weight of the material, the compound fermentation agent is added. The compound fermentation agent is a mixed agent prepared by Bacillus licheniformis and Bacillus subtilis at a mass ratio of 1:1.

[0016] The composting time for the chicken manure compost treated with the compound fermentation agent to reach the harmless target is generally about 20 days, while the time for natural fermentation to reach the same target is usually about 60 days. The growth and reproduction of microorganisms accelerates the degradation of substances in the fermented material, shortens the time for compost to reach the...

Abstract

The invention discloses an organic manure composting fermentation method. Chicken manure is used as a main raw material, the fresh chicken manure is naturally dehydrated till the moisture content is 45-50%, then rice husk, humic acid and a compound fermentation preparation are added and sufficiently mixed and stirred to be uniform, and then all the materials are fed into a solar greenhouse type fermentation workshop for fermentation, wherein in the fermentation process, the temperature of the materials is not larger than 50 DEG C by stirring the materials; when the temperature of the materialsis reduced to 35 DEG C from 50 DEG C, the fermentation is stopped. By adding the rice husk, the microbial reproduction can be accelerated, the degradation of substances in the fermentation materialscan be accelerated, the microbial degradation activity can be improved, and the time for reaching the high-temperature stage can be shortened. By adding KH2PO4, the microbial P nutrients can be increased, and material aging is accelerated. The method is beneficial to environment protection, the nutrient loss is low, and application and popularization are facilitated.

Description

technical field [0001] The field of biological fertilizer of the present invention relates to a production method of biological organic fertilizer. Background technique [0002] The core issue of sustainable agricultural development is to maintain and improve soil fertility and ensure a reasonable cycle of nutrient elements. The key to solving this problem is to apply organic fertilizers, which can improve the yield and quality of agricultural products and reduce environmental pollution at the same time. [0003] Traditionally, the main methods of treating chicken manure as organic fertilizer include drying treatment, silage method, chemical treatment method, thermal spraying treatment method and fermentation composting method, etc. Traditional composting fermentation usually takes 2 to 6 months for chicken manure to mature. During the composting process, the surrounding area of ​​the compost has an unpleasant smell, sewage flows, and mosquitoes and flies breed, becoming an...
