　　Effect of inoculums and anaerobic treatment to fermentation material on anaerobic fermentation of biogas using rice stalks and tea cake powder as raw material were investigated.The result showed that anaerobic treatment to fermentation materials could improve biogas production.The highest accumulate amounts of biogas, the highest concentration of methane when using the tea cake powder as raw were achieved 5305ml, 66.13%, improved 124.1%,20.30% than the control group;while using the rice stalks, these variables are 3759ml, 63.24% and improved 58.81%,15.04% than the control.And after fermentation the content of protein powder, crude fat and sugar in tea cake powder reduced 26.79%, 37.79% and 40.12% compared with raw materials;the degradation rate of lignin and cellulose in the straw are 28.74% and 11.18%.
