摘要
采用室内厌氧培养法,对闽江河口芦苇与咸草湿地土壤甲烷产生潜力动态及外源氮输入的影响进行了初步研究。结果表明,芦苇湿地与咸草湿地土壤甲烷产生潜力最大值均出现在培养后第5 d;季节变化的最高值分别出现在9月和12月,最低值均为7月;外源氮输入对咸草湿地土壤甲烷产生潜力具有抑制作用,并与对照土壤甲烷产生潜力差异显著(p<0.05)。图3,参27。
Methane production potentials from soils of Phragmites australis and Cyperus malaccensis wetland of Min River estuary were determined by laboratory anaerobic incubation experiments. The greatest methane production potential from P. australis wetland and C. malaccertsis wetland soil appeared on fifth day after incubation. There was the highest methane production potential from P. australis and C. malaccensis wetland soils collected in September and December, and the low value both collected in July. Methane production poten- tial from C. malaccensis wetland was inhibited by nitrogen import. The methane production potential after adding nitrogen was significantly different with that of controlling soils（p 〈 0. 05）.
