Abstract:

For a comprehensive understanding of rural biogas development status and issues, our household biogas for 2003-2010 in Shangluo construction, small-scale biogas projects, large and middle scale biogas engineering, construction, usage of the service network, project efficiency was investigated. Results showed that household biogas utilization as a 67.73%, to faeces as the main raw materials and 91.67%; defends 78.52%,73.1% pool farmer biogas fertilizer rates on comprehensive evaluation of biogas as well; farming community biogas normal usage for 67.5% and lianhu, large investment in biogas engineering usage 83.33%, biogas residue, effective utilization of biogas; 50% rural service network basic non-operating income. Through analysis came, mountain biogas construction in the exists of main is households with biogas using rate low, and small biogas engineering construction not specification concentrated gas supply difficulty large, and large farm biogas engineering problem highlight, and follow-up service with not Shang dot difficult to run, and "three biogas" of using efficiency low, made has increased publicity intensity, and increased funds inputs, and strengthening system construction, and specification farm biogas project construction, and strengthening policy protection five article promote biogas career health development of countermeasures.
