1, pig manure fermented organic fertilizer: pig manure is rich in nitrogen, phosphorus, potassium and organic matter, which is a good raw material for making organic fertilizer. But at the same time, pig manure also contains many volatile substances, pathogenic microorganisms, parasitic eggs and heavy metals. If it is directly applied to farmland without treatment, it will bring adverse effects on the ecological environment and human and animal health. If pig manure is to be used as a real organic fertilizer in farmland, it needs further fermentation treatment with the help of fertilizer starter.
2. Pig manure as biogas raw material: biogas fermentation raw material is the material basis of biogas production. In order to ensure sufficient and stable fermentation raw materials for the start-up and fermentation of biogas digesters, it is necessary to select cow dung, pig manure and sheep manure with suitable organic nutrition as fermentation raw materials for start-up before feeding. Pig manure is very suitable as raw material for biogas fermentation, which contains more low molecular weight compounds. The ratio of carbon to nitrogen is suitable for fermentation. Start quickly after entering the pool and produce good gas. With the help of biogas starter, the speed and speed of biogas production can be doubled.
3. Planting aquatic feed with pig manure wastewater: When pig manure is produced in pig farms, it will also produce a lot of sewage, and sewage treatment is also an important part of aquaculture. Water hyacinth and duckweed are planted with pig manure wastewater, in which water hyacinth is resistant to high concentration manure, duckweed is resistant to medium concentration manure, and high concentration organic fertilizer can be absorbed and purified in water hyacinth pond for 7-8 days.
4. Making fish and shrimp feed starter with pig manure: Pig manure is fine in texture and contains more nitrogen, which is easily decomposed by microorganisms and releases effective nutrients that can be absorbed and utilized by fish and shrimp. If used, it will become a good feed for fish and shrimp. However, pig manure contains parasite eggs, some toxic substances and germs, so fish and shrimp cannot be directly fed with pig manure. It must be treated by professional EM bacteria feed starter (microbial starter) to become safe, environmentally friendly and nutritious feed. Feed made of pig manure by microbial starter not only provides cheap and high-quality nutrition for fish (shrimp), but also promotes pig raising and fish farming, forming a good ecological cycle, killing two birds with one stone. In addition, pig manure can also be fermented into livestock feed.
