摘要
稻田CH4和N2O排放存在互为消长的关系,此种关系不受时间、空间及有无水稻植株的影响,考虑稻田CH4减排措施的同时必须兼顾该措施对N2O排放的促进作用。本文从水分管理、施肥管理、水稻品种、甲烷抑制剂及脲酶/硝化抑制剂、耕种方式及耕作制度等方面综述了近年来关于稻田CH4和N2O减排措施的研究,以期从农业实践中总结缓解稻田CH4和N2O排放引起的综合温室效应的生产措施。分析表明,稻田低施氮水平条件下进行中期烤田是减少CH4和N2O排放的有效措施,有机秸秆进行堆腐好氧分解后施入或在休闲期(如秋季或冬季)施入稻田表现出较好的应用前景,施用甲烷抑制剂、脲酶抑制剂及硝化抑制剂和缓释/控释肥料对降低稻田温室气体排放及提高作物产量意义重大。
