Abstract

摘要:以菲和芘为多环芳烃(PAHs)代表物,以紫花苜蓿(Medicago sativa L.)为宿主植物,选用幼套球囊霉(Glomus etunicatum, Ge)、摩西球囊霉(Glomus mosseae,Gm)和层状球囊霉(Glomus lamellosum,Gla)3种丛枝菌根真菌(AMF),研究了接种 AMF下土壤中 AMF菌丝密度、球囊霉素含量与 PAHs去除率的关系。35~75 d,接种 Ge、Gm、Gla处理的土壤中菌丝密度、总球囊霉素含量、易提取球囊霉素含量均随时间延长而显著增大,与不接种对照相比,75 d时接种 Ge、Gm、Gla处理的土壤中易提取球囊霉素含量提高了 48.58%、55.99%和 50.23%,总球囊霉素含量则提高了 38.75%、50.95%和 46.12%。接种 AMF促进了土壤中菲和芘的去除,随着时间 (35~75 d)延长,接种 Ge、Gm、Gla 处理的土壤中菲去除率分别高达 83.4%~92.7%、82.1%~93.8%、86.9%~93.4%,芘去除率达 42.2%~63.5%、43.7%~69.2%、44.6%~66.4%。接种 Ge、Gm和 Gla处理土壤中 AMF菌丝密度、总球囊霉素含量均与土壤中菲和芘的去除率之间存在极显著正相关关系,表明接种 AMF提高了土壤中 AMF菌丝密度和总球囊霉素含量,并促进了土壤中 PAHs的去除。研究结果为阐明丛枝菌根修复 PAHs污染土壤的规律及机理提供了依据。关键词:丛枝菌根真菌(AMF);菌丝密度;球囊霉素;多环芳烃;土壤修复中图分类号:X53 文献标志码:A 文章编号:2095-6819(2016)04-0349-06 doi: 10.13254/j.jare.2016.0086

期刊介绍： Journal of Agricultural Resources and Environment (CN 12-1437/S, ISSN 2095-6819) is a national academic scientific and technical journal. It was founded in 1984, and used to be called Foreign Agricultural Environmental Protection and Agricultural Environment and Development. It is supervised by the Ministry of Agriculture and Rural Affairs, and co-sponsored by the Scientific Research and Monitoring Institute of Environmental Protection of the Ministry of Agriculture and Rural Affairs, and the China Association of Agricultural Ecological Environmental Protection. The journal is one of China's high-quality science and technology journals, China Science Citation Database (CSCD) core journals, Peking University Chinese core journals, China Science and Technology core journals, China Agricultural and Forestry core journals, and Tianjin Outstanding Journals. It is included in the international authoritative databases, such as Scopus database of the Netherlands, the database of the Center for International Agricultural and Biological Sciences Research (CABI) of the United Kingdom, the Stephens Database (EBSCOhost) of the United States, the Ulrichsweb (Ulrich's Guide to Journals) of the United States, EuroPub of the United Kingdom, the Abstracts Journal (AJ) of the Russian Federation, and the Copernicus Index (IC) of the Poland, and so on.
