    摘要:

    研究了广州地区晚季稻田在农业管理措施和肥效基本相同情况下,施用不同肥料类型对稻田甲烷(CH4)排放通量的影响。试验初步表明:晚季稻田CH_4排放基本集中在水稻生长前期;稻田处于灌溉淹水状态是CH_4产生的必要条件;稻田处于干湿期间无明显CH_4排放;施用有机肥料CH_4的排放量明显高于施纯化肥;温度高有利于CH_4排放。

    Abstract:

    This study dealt with the effects of using four kinds of fertilizer application at the same effective fertility level under the normal late rice field management to pad- dy-fields in Guangzhou area on methane emission flux.The result showed that methane emitted significantly in the early growth phase of late rice in paddy-fields,in paddy-fields water immersion was a necessary condition for methane emission,no significant methane emitted in the dry-wet management period;methane emission flux in fields with organic manure applied was higher than that in fields treated with chemical fertilizers;higher soil temperature facilitated methane emission.
