摘要/Abstract

摘要： 采用静态箱-气相色谱法对长期不同施肥处理的稻田甲烷排放进行了手动观测。结果表明,不同施肥处理的稻田甲烷排放具有一致的规律,混施有机肥的处理甲烷排放大于单施氮肥的处理,同施用稻草相比,发酵猪粪处理的甲烷排放较少。文章还对影响稻田甲烷排放的因素进行了讨论。

Abstract: The methane emission in rice fields by longterm fertilization treatments at Wangcheng County of Hunan Province was determined by using the static chamber-GC theory with manual method.The results indicated that the mix of organic fertilizer with nitrogen fertilizer would lead to large numbers of methane emission,while there was only a few methane emission from the treatment with simply nitrogen fertilizer.The methane emission fluxes from manure treatment were less than the straw treatment.The effect factors of the various fertilizer treatments on methane emission in rice fields were discussed.
