摘要
从粤北大宝山采集了30份土壤样品及对应的植物根系样品,分析发现,取自污染区的27份土壤样品中,Cu、Zn、Pb和Cd含量不同程度超过国家(二级)标准.对植物根系样品进行染色,观察丛枝菌根(AM)真菌侵染,发现81.5%的污染区根系样品中存在AM真菌侵染;土壤样品中含有一定数量的各种AM真菌孢子和AM真菌菌丝.调查结果表明,大宝山重金属污染的土壤中存在着多样性的AM真菌.
Arbuscular mycorrhizal （AM） fungi soil. In the present study, 30 soil samples and can help plant to remedy the heavy metal-contaminated the corresponding plant root samples were collected from Dabao Mountains, North Guangdong. The results revealed that the contents of Cu, Zn, Pb and Cd in 27 soil samples from contaminated areas exceeded the national standard at different levels. Following the staining of root samples and the observation for AM fungi colonization, 81.5% of root samples from contaminated areas were found to be colonized by AM fungi. A certain amount of AM fungi spores and hyphae were also present in the corresponding soils. The diverse AM fungi existed in the contaminated soils at Dabao Mountains.
