摘　　要：选择福建水稻研究所吴凤综合试验站为研究样点,采用室内培养-气相色谱法对对照、炉渣、秸秆、生物炭和炉渣+生物炭添加后稻田土壤甲烷与氧化亚氮产生潜力进行了测定和分析。结果表明:在整个观测期内,稻田土壤对照、炉渣、秸秆、生物炭及炉渣+生物炭处理甲烷平均产生潜力分别为0.007 1、0.004 9、1.505 1、0.079 0、0.080 0μg/(g·d),炉渣处理比对照减少了31%,其他处理则出现不同程度增加的趋势;土壤氧化亚氮平均产生潜力分别为0.003 5、0.001 6、0.001 1、0.002 1、0.002 9μg/(g·d),各处理分别比对照减少了54%、69%、40%、17%;炉渣的添加能有效抑制稻田土壤甲烷与氧化亚氮的产生;秸秆、生物炭及炉渣+生物炭处理均能有效抑制稻田氧化亚氮的产生,但并未抑制土壤甲烷的产生。The increment of greenhouse gas emissions is considered as the main reason for global warming,and paddy field is an important source of greenhouse gas emissions. While rice production increases at the same time,and selected an effective method to mitigate greenhouse gas emissions is necessary. Wufeng Experiment Station of Fujian Rice Research Institute was chosen as the study site. Methane and nitrous oxide production potential in the control,and slag,straw,biochar and slag ＋ biochar addition treatments were determined by indoor cultivation-gas chromatogram. The results showed that during the whole observation period,averaged methane production potential were 0. 007 1,0. 004 9,1. 505 1,0. 079 0,0. 080 0 μg /（ g·d）,respectively. Slag addition treatment was decreased by 31 % comparison with the control,and the other treatments were not decreased methane production comparison with that of the control.Averaged nitrous oxide production potential were 0. 003 5,0. 001 6,0. 001 1,0. 002 1,0. 002 9 μg /（ g · d）,respectively. Slag,straw,biochar,and slag ＋ biochar addition treatment were decreased by 54 %,69 %,40 %,17% comparison with the control. Slag addition could inhibit the soil methane and nitrous oxide production from paddy fields,and straw,biochar,and and slag ＋ biochar could effectively suppress the nitrous oxide production,however,not suppress the methane production.
