摘要/Abstract

摘要： 通过盆栽试验，研究了向重金属Pb、Zn、Cd复合污染的土壤中单一或联合添加海泡石和菌根Glomus mosseae、Glomus intraradices对玉米生长及玉米体内重金属浓度的影响。结果表明：联合使用海泡石和菌根Glomus intraradices可显著增加玉米地上部和根部的生物量；与单一处理相比，联合使用海泡石和两种菌根可使菌根对玉米的侵染率提高44.53%~58.80%。海泡石可有效阻隔土壤中的重金属向植株迁移，从而显著降低玉米体内Pb、Cd、Zn的浓度；而另一方面，两种菌根会促进植株体内Pb、Cd、Zn的富集，因此，可利用这两种菌根和一些非经济性作物来去除土壤中的Pb、Cd、Zn。

Abstract: Pot experiments were carried out to study the effects of single treatment or combination treatment of adding sepiolite and mycorrhizal Glomus mosseae, Glomus intraradices in Pb、Zn and Cd contaminated soil on corn growth and concentrations of heavy metals in corn.The results show that the co-treatment of sepiolite and mycorrhizal Glomus intraradice can significantly increase dry weights of terraneous part and subterraneous part of corn.Compared with the single treatment with sepiolite or mycorrhiza, the mycorrhizal infection rates increased by 44.53% to 58.80% for co-treatment（sepiolite+Glomus mosseae and sepiolite+Glomus intraradice）.Sepiolite can effectively block the transference of heavy metal in soil-plant system, and decrease concentrations of heavy metals in corn.On the other hand, mycorrhizal Glomus mosseae and Glomus intraradices can promote the enrichment of heavy metals in corn.Therefore, the heavy metals Pb、Cd、Zn can be removed form contaminated soil using two kinds of mycorrhiza and non-economic Crops.
