摘　　要：对闽江河口稻田甲烷产生潜力及其对炉渣添加的响应特征进行了初步研究,结果表明,(1)稻田土壤甲烷产生潜力在培养第3天出现峰值,10-20 cm土壤是甲烷产生的主要发生层;(2)甲烷产生潜力的剖面变异性低于时间变异性;(3)炉渣添加对0-40 cm土壤层次甲烷产生潜力具有抑制作用,但不同土壤层次甲烷产生潜力对炉渣添加比例的响应有所不同。In order to clarify the methane production potential and reaction to slag adding in paddy fields of Min River entrance,the methane production potential and the reaction to slag adding in the paddy fields were determined.Paddy fields soil production potential appeared the peak at incubation three days and 10-20 cm was the main layer of methane production.The soil profile methane production potential variability was lower than the methane production potential variability various with incubation time.Slag had inhibit function on the whole 0-40 cm soil layers,but the reaction of methane production potential on slag adding ratio was different for various soil layers.
