Abstract: The agricultural production process generated a lot of straw and other agricultural waste, reasonable use of this part of the biomass energy, which can effectively alleviate part of the energy problem. Taking the poultry feeding industry in the Central Chinese Economic District as a research object, a fermentation test on the mixed raw materials of duck manure and straw was conducted to regulate the proportion of fermenting materials so as to explore their biogas production characteristics. Based on the gas generation rate and cumulative gas production of these mixed raw materials in different proportions and using contrasting tests between fermentation materials mixed to different proportions, the research found that the factors affecting fermentation is temperature followed by inoculation concentration and the concentration of fermentation broth. In view of the factors affecting fermentation with the mixture of duck manure and straw, and the cumulative gas production from raw material mixed in different proportions, optimum temperature for mixed anaerobic fermentation is about 30°C and the optimum proportion of raw materials is 2.8:1.
