| 摘 要： | 以冬小麦中麦175为供试品种,利用农田开放式CO_2浓度增高(FACE)系统,研究未来大气高CO_2浓度对冬小麦田间N_2O排放的影响,以及施用硝化抑制剂(2-氯-6-三氯甲基吡啶)是否可以起到抑制冬小麦田间N_2O的排放量升高的潜能。试验结果表明:CO_2浓度升高显著提高冬小麦田间N2O的排放增幅达到67.6%,追肥灌溉后小麦田N_2O排放量较大,随着冬小麦生育进程的推进N_2O的排放量逐渐减少,硝化抑制剂对中麦175田间N_2O排放量的影响并不明显。因此,在未来高CO_2浓度环境条件下,可以通过采取相应的耕作制度和栽培技术措施等来降低冬小麦田N_2O的排放量。试验结果对冬小麦田间是否选择施用2-氯-6-三氯甲基吡啶来控制N_2O的排放起到一定的参考作用。
