| 英文摘要 | To conserve water resources and guarantee food security, a new technology termed as "wet irrigation" is developed and practiced in rice fields; thus, its impact on radiative forcing derived from nitrous oxide (n2o) and methane (ch4) emissions merits serious attention. dicyandiamide (dcd), a kind of nitrification inhibitor, is proposed as a viable means to mitigate greenhouse gas (ghg) emission while enhancing crop productivity. however, little is known about the response of ghg emission and grain yield to dcd application in a rice system under wet irrigation. in these regard, effects of water regime and dcd application on ch4 and n2o emissions, grain yield, global warming potential (gwp), and greenhouse gas intensity (ghgi) from rice fields were studied. for this study, a field experiment, designed: treatment ii (intermittent irrigation), treatment wi (wet irrigation), treatment iid (ii plus dcd), and treatment wid (wi plus dcd), was conducted in jurong, jiangsu province, china, from 2011 to 2012. relative to treatment ii, treatment wi decreased ch4 emission significantly by 49-71 % while increasing n2o emission by 33-72 %. by integrating ch4 and n2o emissions and grain yield, treatment wi was 20-28 and 11-15 % lower than treatment ii in gwp and ghgi, respectively. the use of dcd under wet irrigation reduced n2o emission significantly by 25-38 % (p < 0.05) and ch4 emission by 7-8 %, relative to treatment wi, resulting in a decline of 18-30 % in gwp. due to the increase in n use efficiency, maximal grain yield (6-7 %) and minimal ghgi (22-34 %) was observed in treatment wid. these findings indicate that combined application of n fertilizer and dcd is a win-win strategy in water-saving high-yield rice production with less ghg emission. |
