Using Medicago sativa as raw materials, the experiment was conducted to investigate the effect of different inoculation amount(30%, 40%, 50%) on gas production, gas production efficiency and p H value during the process of anaerobic fermentation, under the condition of 6% mass fraction of total solid(on the basis of inoculation amount 30%), normal temperature(20 ~22 ℃). The results showed that the total gas production was high and reached 3 625 m L when inoculation amount was 40%, and it was 8.05% higher than the experimental group with inoculation amount 30%, slightly less than the experimental group with inoculation amount 50%. The p H value fluctuated in initial stage, but it returned to the appropriate levels soon, it was stable in the entire stage. Comprehensive consideration, inoculation amount 40% is much better for M. sativa.
