Harmless treatment of manure by machine and reuse of farm manure
Organic fertilizer machine harmless treatment of farm manure reuse, fully in line with the sustainable development strategy of agriculture. Therefore, we should give full play to the advantages of organic fertilizer equipment, produce and process organic fertilizer to improve the soil, so as to relieve the pressure of Rural Livestock Manure discharge. Chicken manure organic fertilizer nachine in the treatment process of breeding manure, we must sample, can not only help rural waste disposal, but also make these materials reuse and enhance the value.
There are procedures for composting
First of all, 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 m high and 5-6.7 m wide. Finally, 700-800 kg water is poured on the surface of the compost The upper layer is 3-6cm thick fine soil to keep warm, 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 by compost windrow turner to replenish water; after the second temperature rise in 10 days, the stack will be turned over again to replenish water.
The sign of composting maturity is that 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.
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 in fertilizer production process. 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 ℃.
After a little air drying, it can be crushed by a crusher, granulated by an organic fertilizer granulator, dried and dehydrated by a dryer, and then screened by a screening machine. The finished organic fertilizer is ready for packaging and storage.
