(A) the establishment of biogas is conducive to solving rural energy problems. A family of 3-4 people can build a 10 cubic meter biogas digester. As long as the fermentation raw materials are sufficient and properly managed, the fuel problem of lighting and cooking can be solved.
(2) The establishment of biogas is conducive to promoting the development of agricultural production. After the establishment of biogas, a large number of livestock manure is added to the biogas digester for fermentation, which can not only produce biogas, but also produce a large number of high-quality organic fertilizers, expanding the source of organic fertilizers. All the crops applying biogas fertilizer not only enhanced the drought resistance and frost resistance, but also improved the survival rate of seedlings. The application of biogas fertilizer not only saves the spraying amount of chemical fertilizer and pesticide, but also is beneficial to the production of green pollution-free food.
(3) Setting up biogas is beneficial to the development of animal husbandry. After running biogas, it will help solve the contradiction of "three materials" (fuel, feed and fertilizer) and promote the development of animal husbandry.
(4) The establishment of biogas is conducive to improving sanitary conditions. All farmers who have built biogas digesters realize that using biogas as fuel is smokeless, clean and convenient. Some excrement, garbage and domestic sewage are good raw materials for biogas fermentation. As these raw materials enter the biogas digester, bacteria and parasite eggs are killed by closed fermentation in the biogas digester. Thereby improving the environmental sanitation conditions in rural areas and benefiting the health of people and livestock.
(5) Setting biogas is beneficial to protect the ecological environment. Setting up biogas can solve farmers' fuel problem, reduce deforestation and the damage of cattle and sheep to Shan Ye, protect forest and grass resources, promote afforestation development, reduce soil erosion and improve agricultural ecological environment.
(six) the establishment of biogas is conducive to the liberation of labor. After biogas is set up, a large amount of labor that farmers used to spend collecting firewood and transporting coal can be saved and put into the front line of agricultural production. By using biogas, rural women are liberated from traditional cooking methods, saving cooking time and reducing housework. Biogas is a kind of clean energy, so all countries are promoting it in rural areas.
