Abstract:

In order to provide better understanding and handling of the influence of straw application on agricultural greenhouse gas emissions in China. The author reviewed the influences of straw application on agricultural greenhouse gas, such as CO2, N2O and CH4 based on literatures in recent year. Research showed that straw application could increase soil CO2 and CH4 emissions fluxes, but the influence on N2O emission fluxes was uncertainty. The author analyzed the influence factors of straw application on agricultural greenhouse gas emissions, the present and future research needs about straw application on the fluxes greenhouse gas from farmland soil were discussed. Straw application influenced agricultural greenhouse gas emissions in China, the influence degree and influence mechanism of each greenhouse gases were different.
