Problems solved by technology

[0002] Fertilizers mainly contain nitrogen, phosphorus, and potassium elements to supplement the lost nutrients for the soil, thereby increasing the yield of crops. However, with the frequent and single use of chemical fertilizers, it will bring adverse effects on the soil environment, and the soil is lacking sufficient nutrients. Under the condition of organic matter, the soil aggregate structure is difficult to form, and the adhesion between soil particles is weakened, which reduces the water retention capacity of the soil.

Embodiment 1

[0027] Embodiment 1: A method of composting mixed pig manure and rice straw. Pig manure is collected, mixed with additives, turned into a ridge, and the height is 1-1.6m. Cover with a film to moisturize;

[0028] The ridged pig manure is turned once every 8 days. During the turning process, the mixture of pig manure and soil is taken and subjected to high temperature treatment. After the treatment, it is piled back to the original place and covered with a film;

[0029] It can reach the degree of decomposing in 20 days. At this time, the pig manure is turned repeatedly to make it disperse into fine particles;

[0030] Lay the straw flat on the square, dry it for 4 hours, spray the nutrient solution once every hour, turn it over, continue to dry it for 4 hours, spray the nutrient solution once every hour;

[0031] Cut the straw into 2-3cm long; mix the rice bran and straw, the initial moisture content of the compost raw material is 55-65%, and compost for 30 days;

[0032] Ma...

Embodiment 2

[0048] Embodiment 2: A method of composting mixed pig manure and rice straw, collecting pig manure, adding additives to mix well, turning the pile into ridges, the best height is 1-1.6m, and making multiple air outlets at equal distances on the ridges, and finally Cover with a film to moisturize;

[0049] The ridged pig manure is turned once every 8 days. During the turning process, the mixture of pig manure and soil is taken and subjected to high temperature treatment. After the treatment, it is piled back to the original place and covered with a film;

[0050] It can reach the degree of decomposing in 20 days. At this time, the pig manure is turned repeatedly to make it disperse into fine particles;

[0051] Lay the straw flat on the square, dry it for 4 hours, spray the nutrient solution once every hour, turn it over, continue to dry it for 4 hours, spray the nutrient solution once every hour;

[0052] Cut the straw into 2-3cm long; mix the rice bran and straw, the initial...

Abstract

The invention provides a pig manure and straw mixed composting method. The method comprises steps as follows: collecting pig manure, and preparing small particles; composting straw, punching a plurality of air outlets in the composted straw, digging a pit in the center of the upper end, spreading the particles in the pit, and covering the pit with a film for moisturizing; opening the film in 30 days, and putting composted fertilizer in a high-temperature oven for high-temperature treatment; after treatment, mixing the treated fertilizer with nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer in a ratio of 10: 0.3: 0.2: 0.7, and allowing the mixture to stand for 1 day. The pig manure and the straw are combined and composted, and the unique biological composition provides conditions for rapid microbial growth and reproduction. Therefore, microbes can grow and reproduce in quantities rapidly in the initial stage of compositing, not only is water-rich agricultural plant waste degraded quickly, but also rapid degradation of other non-degradable urban organic plant waste is promoted, the rate of organic degradation during composting is increased by 11%-17%, and composting time is shortened by 20 days or longer.

Description

Technical field: [0001] The invention relates to a composting technology, in particular to a method for composting mixed pig manure and rice straw. Background technique: [0002] Fertilizers mainly contain nitrogen, phosphorus, and potassium elements to supplement the lost nutrients for the soil, thereby increasing the yield of crops. However, with the frequent and single use of chemical fertilizers, it will bring adverse effects on the soil environment, and the soil is lacking sufficient nutrients. Under the condition of organic matter, the soil aggregate structure is difficult to form, and the adhesion between soil particles is weakened, which reduces the water retention capacity of the soil. When the soil cannot retain sufficient moisture, even high-quality fertilizers are not easy to release nutrients under favorable conditions. In order to solve the problems caused by the long-term use of single chemical fertilizers, organic fertilizers have appeared on the market. Org...
