Cattle dung is a good fertilizer for the production of organic fertilizer. Dry cow manure contains 10%-20% crude protein, 1%-3% crude fat, 20%-30% nitrogen-free extract and 15% crude fiber. Some scholars have found that dried cow dung can become a particularly high-quality organic fertilizer product after fermentation. It can fluff the soil, improve soil compaction, trace elements in the soil, and improve soil fertility.
The cow dung organic fertilizer production line is a complete set of equipment for processing organic fertilizer with cow dung as raw material. The cow dung processing machine can be used to first pump the cow dung from the manure tank to the equipment through a slurry pump. After the equipment is dehydrated, the water content is 40%. You can also use crops such as straw and rice bran (including N\P\K) as filling materials, and then sprinkle with biological inoculant, 1KG inoculant mixed with 20KG of water and moved into the raw materials, which can ferment 1 ton of raw materials. Turn and toss once every 1-2 days. Generally, it can be completely decomposed in 7-10 days.
Cattle waste processing machine for windrow composting is to pile the raw material mixture into long strip piles or piles, and maintain the aerobic state in the pile by manual or mechanical regular turning and natural ventilation. It is carried out under aerobic conditions. Fermentation decomposition. The cross-section of the stack can be trapezoidal, irregular quadrilateral or triangular. The windrow composting fermentation is to spread the materials into rows and stack them in the open air or under a scaffold. Each row of materials is 2-3 m wide and 1-1.5 m high. The length depends on the actual situation. A ventilation pipe can be installed under the material pile. , Or not to install ventilation facilities. The characteristic of bar-stack composting for the treatment of cow dung is that the materials can be placed closer to the farmland, and special workshops are not required, but the processing time is relatively long. If the open air method is adopted, it will be greatly affected by the weather and seasons.
Groove fermentation for cattle manure: This is currently an effective method for the treatment of cow dung, and it is also suitable for the commercial production of cow dung organic fertilizer, which is conducive to standardized production. It uses biological characteristics combined with mechanized technology to completely decompose cow dung using natural microorganisms or inoculated microorganisms and convert organic matter into organic matter, carbon dioxide and water. This method has a short fermentation time, generally about 15 days to completely ferment the cow dung. , And easy to achieve factory-scale production, not affected by the weather and season, causing little pollution to the environment, which is conducive to the commercial production of cow manure organic fertilizer. Depending on the equipment, the width of the fermentation tank is generally 3-20m, the depth is generally 0.8-1.5m, and the length is 50-100 m, which can be designed according to actual conditions.
After the cat dung is fermented, they can be directly processed for granulation. If the raw materials have not been processed, refer to the above methods for fermentation. The complete set of equipment for the cow dung organic fertilizer production line requires a compost turner machine, a semi-wet material type of grinding machine, a screening machine for cattle dung fertilizer, a mixing machine of horizontal type, a disc granulator, a dryer, and a cooling machine. , Roller screening machine, film coating machine, automatic quantitative packaging machine and other equipment.
Green ecological organic fertilizer is produced by disposing cow dung and crop straw as the main raw materials, using multi-dimensional compound enzyme bacteria. The multi-dimensional complex enzyme bacteria is a microecological fermentation preparation composed of 106 beneficial microorganisms, such as heat-resistant bacillus group, lactic acid bacteria group, bifidobacterium group, yeast group. It can produce a variety of enzymes. It can decompose and decompose potassium, and can decompose the residues of chemical pesticides and fertilizers, which has the effect of increasing production, quality and disease resistance in planting and breeding industries.
