二、生态农业各系统运行效益分析1.沼气的应用沼气池带温发酵,运行稳定,平均日产沼气618立方米,年产22.56万立方米,相当于原煤450吨,除冬季沼气池增温耗煤47吨外,净节约原煤403吨,按市场价每吨煤235元计,沼气的年收益为9.47万元。沼气作为燃料,为村民提供生活用能,为炒制茶叶提供燃气,为养殖棚舍增温供暖。2.沼液的应用鸡粪和猪粪等有机物经过厌氧发酵后,除碳水化合物被厌氧菌分解转化为甲烷和二氧化碳外,其余大
Second, the ecological agriculture system operating efficiency analysis 1 biogas application Digester with temperature fermentation, stable operation, the average daily production of 618 cubic meters of biogas, with an annual output of 225,600 cubic meters, equivalent to 450 tons of raw coal, in addition to the winter digester heating consumption 47 tons of coal, the net savings of 403 tons of raw coal, according to the market price of 235 yuan per ton of coal, biogas, the annual revenue of 94,700 yuan. Biogas as fuel for the villagers to provide energy for life, to provide fuel for the frying of tea, greenhouse heating for breeding shelters. 2. Application of biogas slurry After the manure and pig manure and other organic matter after anaerobic fermentation, in addition to the decomposition of carbohydrates by anaerobic bacteria into methane and carbon dioxide, the other large
