Pig manure fermentation production of organic fertilizer has broad prospects

At present, the number of live pigs in China is about 470 million heads, and the scale of production is higher and higher. The problem of environmental pollution caused by pig manure discharge has become increasingly prominent. According to statistical data from the relevant departments, the daily excretion of pig manure in China amounts to 900,000 tons, and the environmental pollution caused by the accumulation of pig manure is indeed worrying. At the same time as causing pollution, many pig farms find it very difficult to handle and dispose of the pig manure. Especially for large-scale pig farms, environmental pressure is high and the use of pig manure resources is even more urgent.

At the time, pig manure itself is a good source of organic fertilizer, in addition to a lot of organic matter and nitrogen, phosphorus, potassium and other trace elements and other plant essential nutrients, but also contains a variety of biological enzymes and microorganisms. However, there are many disadvantages to applying untransformed pig manure directly to farmland or simply drying it to make fertilizer. Direct application of uncommustated pig manure causes transmission of pests and diseases and animal diseases; large excreta, high water content, and inconvenience in transportation and use. Therefore, the use of pig manure as a fertilizer requires harmless, stabilizing and reducing treatment; the state has ordered the prohibition of transportation of pig manure.

Therefore, pig manure must be decomposed by aerobic fermentation (Kimbera microbial fertilizer starter) before it can be used as a fertilizer, so that parasite eggs and pathogenic microorganisms can be killed after treatment, and the spread of infectious diseases through the land can be prevented, and food safety production can be promoted. Harm and stabilize, can also be made into various types of organic fertilizers according to the needs of agricultural production, to build a new economic growth point for the pig farm. Therefore, the production of organic manure from swine manure is undoubtedly one of the effective means for pig farmers to finally solve the pig manure outlet.

First, the process of producing manure by fermenting pig manure

1, raw material pretreatment

Pig manure fermentation conditions include moisture content, carbon-nitrogen ratio, oxygen concentration, and pH, among which raw material moisture content and carbon-nitrogen ratio are particularly critical. Fresh pig manure is a kind of sticky wet material. In order to achieve a satisfactory fermentation effect, fermentation conditions must first be met. After several years of user experience, the golden babe fertilizer starter proved that the moisture content of the fermented organic fertilizer is the most suitable for 60 to 65%. If the moisture content is too high, it will hinder the ventilation, the temperature will be difficult to rise, and the decomposition rate will drop significantly, resulting in an anaerobic condition that is not conducive to the growth of aerobic microorganisms and is likely to generate malodorous gases such as H2S. Too low water content cannot meet the requirement for microbial growth, and organic matter is difficult to decompose.

Reasonably adjusting the ratio of carbon to nitrogen in compost raw materials is an effective way to accelerate compost maturity and increase humification. Under normal circumstances, the best range of carbon/nitrogen ratio (C/N) is 25:1~30:1. If the C/N is too high, the source of nitrogen needed for microbial growth and reproduction is limited, the rate of microbial reproduction is low, the decomposition rate of organic matter is slow, and the fermentation time is long; if C/N is too low, the energy source needed for microbial growth and reproduction is affected. The restriction is that the temperature of the fermentation rises slowly, excess nitrogen is released and the ammonia is released, organic nitrogen is lost, and unpleasant odors are also emitted.

Adding appropriate amount of carbon source auxiliary material in pig manure is an effective way to adjust the moisture and carbon nitrogen ratio. Carbon source auxiliary materials include crop straw, rice bran, peanut shell, Chinese medicine residue, mushroom mushroom stick of waste gas, cotton seed shell and sawdust, etc. Local conditions choose the most suitable and cheap raw materials. Before the material enters the fermentation tank, the organic raw materials and the carbon source auxiliary materials need to be evenly pre-mixed.

2, the amount. 1 ton of organic material (about 2.5 to 3 tons of fresh material) plus 1 kg of Kinpo Fertilizer, can be mixed and fermented. Dilution: Add 5 to 10 kg of rice bran (or bran, corn flour, etc. substitute) per kilogram of starter, mix and dilute, then spread evenly into the material pile, and the use effect will be better.

3, stacking materials, manual operation: a stack of materials is generally not less than 4 or not less than 500 kilograms, height 120-150 cm, width of 2 meters or so, 2 meters long, ambient temperature 15 to 20 degrees or better , If the temperature is too low in winter or rainy days, try to warm up. Mechanical operation: According to the process requirements.

4, material overturned. Garbage fertilizer starter is a good (consumption) oxygen starter, it is appropriate to cover with a straw and other breathable cover. General materials will rise to above 50-60Â°C within 48 hours. On the third day, the temperature will be higher and it will start to fall. The temperature of the material after tipping will further increase rapidly. If the stack temperature exceeds 65Â°C, it should be turned again. The inverted and overturned material should be poured into the heap. When taking care of ventilation when tipping over, use a 5 to 10 cm tipped rod to drill holes in the stack. Under normal circumstances, turn to 2-3 times, about a week in summer, 10 days in winter can be fermented to complete.

5, the sign of completion of fermentation. The fermentation product had no odor of pig manure and was slightly sprinkled with aroma or earthy taste, indicating that the fermentation was completed. Fermented bio-organic fertilizer, because it has been fully fermented and decomposed, must be applied to shallow fertilization to avoid deep application.

Second, the benefits of pig manure fermentation production of organic fertilizer

1. The use of organic waste such as swine manure from pig farms and fermented by the microbial fertilizer fermentation agent of Jinbao, and then processing of organic fertilizers meet the requirements of the development of industrial policies for national environmental protection, ecological agriculture and organic foods.

2. According to years of experience in fertilizer production, 10,000 pig farms produce 10 tons of pig manure, 3,600 tons of fertilizer per year, 1,800 tons of organic fertilizer, (700 yuan per ton organic fertilizer market, 500 yuan per ton of organic fertilizer removal cost) Net profit of 200 yuan per ton, 1800 tons * 200 yuan / ton = 360000 yuan.

3, large-scale pig farms using pig manure as raw material to produce organic fertilizer considerable benefits, that is to solve the environmental problems, but also solve the epidemic problem, but also change waste into treasure to contribute to agricultural production, the prospects are very broad.
