preparation example Construction

[0024] Preparation of microbial fermentation composition: first mix the microbial mixed bacterial agent, combined enzyme agent and water according to the required ratio to form a degradation liquid, then add organic raw materials (the particle size of the straw is 10-20mm) to the degradation liquid and mix well To obtain the mixed material, then adjust the C / N mass ratio of the mixed material to 25-35:1, the initial moisture content is 50-60%, and place the mixed material in a compost reactor for aerobic fermentation for 7-10 days to obtain The microbial fermentation composition, wherein, the temperature of the aerobic fermentation is 25-50°C, and during the whole aerobic fermentation process, air with an oxygen concentration of 10%-20% is continuously fed from the bottom of the composting reactor;

[0025] Preparation of organic fertilizer: first crush the microbial fermentation composition, and then mix it with urea according to the required ratio.

Embodiment 1

[0038] A bio-organic fertilizer using livestock and poultry manure as raw material, its raw material composition and weight ratio are: microbial fermentation composition 80, urea 15, calcium hydrogen phosphate 5, potassium chloride 3, wherein, the microbial fermentation composition The composition of the raw materials and their weight ratios are: 1.5 parts of the mixed microbial agent, 0.5 of the combined enzyme agent, 100 of the organic raw material, 10 of the water, 2 of sodium lauryl sulfate, and 0.5 of the salt. The mixed microbial agent includes Bacillus subtilis, giant Bacillus, jelly-like bacillus, bacillus cereus, bacillus licheniformis, aspergillus niger, aspergillus oryzae and bacillus thuringiensis, the inoculation amount of each bacterium is 0.2% of organic raw material weight, and described combined enzyme agent is 5000U / g protease, 1000U / g cellulase, 3000U / g dextranase, 2000U / g pectinase, 5000U / g lipase mixture, the organic raw materials are pig manure, horse man...

Embodiment 2

[0040] The difference with Example 1 is:

[0041] The raw material composition and weight ratio of the bio-organic fertilizer are: microbial fermentation composition 85, urea 16, calcium hydrogen phosphate 6, potassium chloride 3.5, wherein, the raw material composition and weight ratio of the microbial fermentation composition are : microbial mixed bacterial agent 1.2, combined enzyme agent 0.6, organic raw material 100, water 15, sodium lauryl sulfate 2.2, salt 0.7, described combined enzyme agent is 4000U / g protease, 2000U / g cellulase, 5000U / g g dextranase, 3000U / g pectinase, 7000U / g lipase, the organic raw material is a mixture of cow dung, sheep dung, chicken manure, and straw mixed in a weight ratio of 1:1:0.5:1 .

Abstract

The invention relates to biological organic fertilizer taking livestock excrements as raw materials. The biological organic fertilizer comprises the following raw materials in parts by weight: 80 to 100 parts of a microbial fermentation composition, 15 to 20 parts of urea, 5 to 10 parts of calcium hydrogen phosphate and 3 to 5 parts of potassium chloride, wherein the microbial fermentation composition is obtained by performing medium-temperature aerobic composting treatment on a microbial mixed bacterial agent, a combined enzyme agent, an organic raw material and water according to the weightratio of (1-1.5):(0.5-1):100:(10-20) at 25 to 50 DEG C; the microbial mixed bacterial agent comprises bacillus subtilis, bacillus megatherium, bacillus mucilaginosus, bacillus cereus, bacillus licheniformis, aspergillus niger, aspergillus oryzae and bacillus thuringiensis; the combined enzyme agent is a mixture of protease, cellulase, glucanase, pectinase and lipase; and the organic material is amixture of livestock excrements and straws. According to the design, stink and damage to soil are not liable to occur, and the composting period is short.

Description

technical field [0001] The invention belongs to the field of bio-organic fertilizers, in particular to a bio-organic fertilizer using livestock and poultry manure as a raw material. Background technique [0002] Waste is an important material basis for agricultural development. The long-term and large-scale use of chemical fertilizers in the production process of traditional agriculture and forestry will lead to soil compaction and degradation of the quality of agricultural products, the use of fertilizers will decrease, and the human living environment will be seriously polluted and destroyed. With the improvement of people's living standards, human beings have fully realized that it is necessary not only to survive in a good natural environment, but also to consume high-quality, safe and hygienic agricultural products. What plays a key role in this link is to use more bio-organic fertilizers in production and cultivation to reduce dependence on chemical fertilizers. [0...
