菌根在污染土壤生物修复中的作用

摘要

Mycorrhiza,existing extensively in nature,are symbioticassociations of plant roots with certain soil fungi. They can improve the host plant in nutrient uptake and growth,and hence its endurance and resistance to environmental stress. Therefore,mycorrhiza-accreted plants can be used as a suitable bioremediation carrier. A review is made of studies,at home and abroad,on role of mycorrhiza in bioremediating soils polluted by non-organic,organic and radioactive contaminants.%菌根是土壤真菌-植物根系形成的共生体，广泛存在于自然界中，它能增强植物的吸收能力，改善植物的生长，提高植株的抗逆能力和耐受能力等。所以，菌根化植物可作为很好的生物修复载体。本文主要从无机、有机以及放射性污染3方面对国内外关于菌根在污染土壤生物修复中的作用进行了综述。
