Abstract：In this paper, vegetable soil as the experimental soil, through the indoor pot experiment, study the dif-ferent biochar materials (bamboo powder, rice straw), different kinds of biomass carbon amounts ( 0.5%, 1%dry soil) effects on soil methane and carbon dioxide emissions, nitrous oxide. The test results show that, compared with not adding biochar, biochar addition can be effective in reducing greenhouse gases emissions;the same add-ed effective straw biochar is higher than that of bamboo biochar;the same raw material of biochar, the more add-ed amount of biochar the less greenhouse gas emissions;applied early in the biomass carbon, effects on methane emission less, but with the time, the effect is enhanced, and the nitrous oxide, carbon dioxide emissions is having the opposite effect;biochar impact on nitrous oxide strength higher than that of methane and carbon dioxide.
