Abstract:The research on the effect of drip irrigation on the emission of CO2 and N2O and its impact mechanism was helpful to understand the influence of irrigation pattern changes on carbon and nitrogen cycles of agro-ecosystem. And they were also significant for the improvements of agricultural irrigation management and mitigation in greenhouse gas emission. In this paper, different impacts of drip irrigation on CO2 and N2O were summarized and the influence mechanism of soil moisture, soil temperature, soil nutrients, soil structure and soil microorganism on the production and emission of CO2 and N2O from agricultural soil were analyzed. Meanwhile, the uncertainties in the influence of drip irrigation on atmospheric greenhouse effec as well as the existing problems of current research were also discussed.
