Based on a two-year field experiment located at Shenyang Applied Ecological Experiment Station of Chinese Academy of Sciences,we examined the effects of stabilized N fertilizer combined with straw returning on rice yield and emission of N_2O and CH_4 in aquic brown soil. Six treatments were set up,i.e. control (CK) ,urea(U) ,urea+urease inhibitor+nitrification inhibitor (U+I) , straw (S) ,straw+urea (S+U) ,straw+urea+ urease inhibitor+nitrification inhibitor (S+U+I) . The results showed that urea application increased rice yield,cumulative N_2O and CH_4 emission,and global warming potential. The treatment of U+I significantly mitigated cumulative N_2 O emission. Returning rice straw to the field significantly increased cumulative N_2O emission,cumulative CH_4 emission,global warming potential,and greenhouse gas emission intensity. The S+U+I treatment had the highest rice yield and greenhouse gas emission intensity. U+I treatment had the the second highest rice yield and the lowest greenhouse gas emission intensity. Rice yield in the S treatment showed no significant difference with CK. Our results indicated that S+U+I and U+I are relatively better agricultural strategies compared with other treatments in paddy fields on aquic soil.
