Production of fermentation compost with small organic fertilizer
In the organic fertilizer production process, the raw material straw (which can also contain cellulose, hemicellulose and lignin such as weeds, fallen leaves, garbage, etc.) is cut into about 6-7 cm long, and mixed evenly according to the proportion of 500 kg of straw, 300 kg of mule and horse manure (or pig manure and cow dung) and 100 kg of human manure and urine, and pile them into a rectangular pile of 1.7-2 meters high and 5-6.7 meters wide, and finally poured 700-800 kilograms of water, A layer of 3-6cm thick fine soil is covered on the surface of compost to keep heat, water and fertilizer. After about one week, the stack temperature will rise to about 60-70 ℃ (the time in winter is relatively long). After 10 days, the stack can be turned over once again to replenish water; after the second temperature rise in 10 days, the stack will be turned over again to replenish water.
The mark of composting maturity in organic fertilizer production line is that the composting materials (such as straw) are nearly black, rotten and smelly. At this time, the compost can be compacted and sealed with soil to keep nutrients in reserve.
The organic fertilizer production line with an annual output of 5000 tons requires about 700m fermentation tank plant, 500m processing plant and 400m warehouse and office area. The organic fertilizer production plant cost is about 350000 to 500000 yuan.
In the production of pollution-free vegetables, experts recommend the use of high-quality organic manure such as compost. When composting, in order to make the compost meet the national health standards, the key step is to increase the temperature of compost. Generally speaking, the temperature must be raised to 60-70 ℃ and maintained at this temperature for 6-7 days, so as to achieve good fertilizer efficiency and kill harmful organisms Fruit. A thermometer can be used to measure the temperature, and it can be maintained for 10 days after 60 ℃.
