农村沼气建设是科学利用生物质能的有效途径,可实现以资源消耗性的常规农业向以资源循环节约型的生态农业转变,是发展循环经济、建设节约型社会的有效途径。沼气建设可实现“作物—畜—沼—肥—作物”良性生态循环,畜禽粪便与秸秆一起投入沼气池,获得清洁的沼气能源和粮经作物必需的优质有机无公害沼肥,促进了新农村建设和生态农业可持续发展。
The construction of biogas in rural areas is an effective way to utilize biomass energy in a scientific way. It can realize the transformation from conventional agriculture with resources consumption to eco-agriculture with resource-saving and circular economy. It is an effective way to develop circular economy and build a conservation-oriented society. Biogas construction can realize the virtuous ecological cycle of “crop-livestock-biogas-fertilizer-crop” and livestock and poultry manure together with straw into biogas digesters to obtain clean biogas energy and high-quality organic pollution- New rural construction and sustainable development of ecological agriculture.
