[Method]Using the corn stalks as raw material for fermentation, different proportions of anaerobic sludge were vaccinated. Then, using the batch fermentation process, anaerobic fermentation was conducted under 38℃. [Result]After 50 d of fermentation, most of ma- terials in straw decomposed. When the ratio of anaerobic sludge and straw was 10：3 （the TS rate was 0.57 and VS rate was 0.46 for both） and the total TS concentration was at 10.16%, the straw gasification effect was optimal, in which the gas production rate was 370 mL/g TS and the methane content of biogas was 56.04%.
