preparation example Construction

[0021] Preparation of the microbial fermentation composition: first mix the combined enzyme agent, the microbial mixed inoculum and water in the required proportions to form a degradation liquid, then add organic raw materials to the degradation liquid and mix to obtain the mixture, and then adjust the mixture The C / N mass ratio is 25-35:1, the initial moisture content is 50-60%, and the mixture is placed in a composting reactor for aerobic fermentation for 7-10 days to obtain a microbial fermentation composition. The temperature of the aerobic fermentation is maintained at 25-50°C. During the entire aerobic fermentation process, air with an oxygen concentration of 10%-20% is continuously introduced from the bottom of the composting reactor;

[0022] Preparation of organic fertilizer: firstly crush the microbial fermentation composition, and then mix it with urea in the required ratio.

[0023] The main raw materials used in the present invention are described as follows:

[0024] B...

Embodiment 1

[0035] A bio-organic fertilizer using food waste as a raw material. The raw material composition and weight ratio are: microbial fermentation composition 80 and urea 10, wherein the raw material composition and weight ratio of the microbial fermentation composition are: microorganisms Mixed microbial agent 1, combined enzyme 0.5, organic raw material 100, water 20, sodium lauryl sulfate 1, the raw material composition of the microbial mixed microbial agent is Bacillus subtilis, Bacillus megaterium, Bacillus jelly-like, wax Bacillus-like, Bacillus licheniformis, Aspergillus niger, Aspergillus oryzae and Bacillus thuringiensis, the inoculation amount of each bacteria is 0.2% of the organic raw material, and the combined enzyme is 5000U / g protease, 1000U / g cellulase, 3000U / g glucanase, 2000U / g pectinase, 10000U / g lipase, the organic raw material is a mixture of food waste and straw in a weight ratio of 1:1.

Embodiment 2

[0037] The difference from Example 1 is:

[0038] The raw material composition and weight ratio of the bio-organic fertilizer are: microbial fermentation composition 85 and urea 8, wherein the raw material composition and weight ratio of the microbial fermentation composition are: microbial mixed bacteria agent 1.3, combined enzyme agent 0.8. Organic raw material 100, water 18, sodium lauryl sulfate 1.5, the inoculum of each strain in the microbial mixture is 0.3% of the organic raw material, and the combined enzyme is 8000U / g protease, 2000U / g cellulase, 5000U / g glucanase, 3000U / g pectinase, 15000U / g lipase, the organic raw material is a mixture of food waste and straw in a weight ratio of 2:1.

Abstract

The invention discloses a biological organic fertilizer. The biological organic fertilizer comprises the following materials in parts by weight: 80-100 parts of a microorganism-fermented composition and 5-10 parts of urea, wherein the microorganism-fermented composition is obtained by carrying out medium-temperature aerobic composting treatment on a microorganism mixed agent, a combined enzyme agent, an organic material and water in a weight ratio of 1-1.5:0.5-1:100:10-20 at a temperature of 25-50 DEG C; the microorganism mixed agent comprises the materials of: bacillus subtilis, bacillus megaterium, 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; the organic material is a mixture of kitchen waste and straws. The biological organic fertilizer disclosed by the invention not only is not likely to generate odourand damage soil, but also is short in composting period.

Description

Technical field [0001] The invention belongs to the field of biological organic fertilizer, and specifically relates to a biological organic fertilizer using food waste as a raw material. Background technique [0002] Waste is an important material basis for agricultural development. In traditional agriculture and forestry, the long-term and large-scale use of chemical fertilizers in the production process will cause soil compaction and degradation of agricultural products, reduced fertilizer utilization, and severe pollution and destruction of the human living environment. With the improvement of people's living standards, mankind has fully realized that not only a good natural environment is needed for survival, but also the consumption of high-quality, safe and healthy agricultural products. The key to this link is the use of bio-organic fertilizers in production and cultivation to reduce dependence on chemical fertilizers. [0003] Bio-organic fertilizer is a type of microbia...
