利用实验室模拟沼气装置在恒温条件下研究了稻草产沼气模拟模型和最大产气量的C/N、C/P比例.结果表明,稻草日累计产沼气动态过程符合Peal-Reed模型,而最大累计产沼气量与C/N、C/P比值均符合二次抛物线模型,进一步分析二次模型可得出最大产气量的C/N和C/P比值分别为27.5和163.1,最大产沼气量分别为186.7 L/kg和138.3 L/kg.

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.
