【Objective】 This study specified the effect of controlled release fertilizer (CRF) and straw mulching upland rice (MUR) on CH_4 and N_2O fluxes,cumulative emissions, greenhouse effect and emission intensity of late rice field to explore effective measures for mitigating greenhouse gas emissions and planting rice scientifically.【Method】 Three treatments, traditional paddy rice (PR), straw mulching upland (MU), and straw mulching upland fertilized with controlled release fertilizer (MUCRF) were designed with three replicates for each treatment for the farm of South China Agriculture University. Closed-chamber technique was conducted to collect CH_4 and N_2O fluxes from PR, MU and MUCRF treated fields every day after rice transplanting to compare their contributions to global warming. 【Result】 CH_4 emission of PR concentrated in seedling stage, initial tillering stage and maximum tillering stage with the duration of 35 days. CH4 emissions of MU and MUCRF concentrated in seedling stage and initial tillering stage with the duration of 15 days. CH4 cumulative emissions of MU and MUCRF were significantly lower than that of PR with ratios of 20.00% and 17.98%. Little N_2O was emitted from PR at the stage of drying paddy in sunshine. However,N_2O emission of MU concentrated in maximum tillering stage and the emission peak last for 10 days. Its N_2O cumulative emissions were higher than that of PR. N_2O emission of MUCRF concentrated in initial tillering stage and the emission peak last for 7 days. There was no difference in N_2O cumulative emissions between MUCRF and PR. However,N_2O cumulative emissions of MUCRF were lower than that of MU. MU had no significant difference on global warming potential and greenhouse gas emission intensity,but combined MU and CRF decreased global warming potential and greenhouse gas emission intensity significantly by 77.66 % and 76.47%, respectively.【Conclusion】 Straw mulching upland fertilized with CRF was an effective measure to significantly reduce the greenhouse effect of rice field and a scientific mode for rice cultivation.
