YU Ai-he1,LIU Zhao-bing2,ZHAO Ke-qin1,CAI Li-xiang3,JI Xiong-hui2,SHI Li-hong2(1.Hunan Mechanical & Electrical Polytechnic,Changsha 410151,China;2.Hunan Institute of Soil and Fertilizer,Changsha 410125,China;3.Hunan Academy of Agricultural Science,Changsha 410125,China)  
The biogas producing model and the optimal C/N,C/P ratio were studied using simulative constant-temperature biogas-pool set in laboratory.The results showed that the dynamic of daily accumulative biogas yield with rice straw was significantly accorded with Peal-Reed model,and the most accumulative biogas yield was markedly quadratic related with C/N,C/P ratio,and the C/N,C/P ratio was 27.5 and 163.1,and the most biogas yield was 186.7 L/kg and 138.3 L/kg.
