伊宁县发展沼气,从八三年以来共新建沼气池114个,已投入使用的97个占85.0％,基本上做到了建一个成一个。实践证明推广沼气不但能充分合理地利用本地农业自然资源;解决农户的燃料、照明等困难,而且可以积攒优质有机肥,增加肥料有利于低产土壤的改良和农作物产量的提高。由于生物质的多次利用,沼气发酵,净化了环境,使生态循环日趋合理,得到平衡。农村沼气具有投资少,见效快、收益大等优点。现就沼气的经济效益,简略的分析如下:
Yining County, the development of biogas, since 1983, a total of 114 new digesters, 97 have been put into use accounted for 85.0%, basically done to build one into a. Practice has proved that the promotion of biogas can not only make full and reasonable use of the local agricultural natural resources; solve the difficulties of farmers in fuel and lighting, but also save high-quality organic fertilizer and increase fertilizer, which is conducive to the improvement of low-yielding soils and the improvement of crop yield. Due to the multiple utilization of biomass, biogas fermentation, purification of the environment, the ecological cycle is becoming more reasonable and balanced. Biogas in rural areas with less investment, quick, big benefits and so on. Now on the economic benefits of biogas, a brief analysis is as follows:
