有机污染土壤中菌根的作用

摘要/Abstract

摘要： 近年来,土壤有机污染问题日益突出,传统的修复方法存在局限性。菌根是植物根系与菌根真菌形成的共生体,能增强植物的逆境抗胁迫能力,对于促进有机污染物的降解和转化具有积极的作用。本文主要阐述了石油、多环芳烃、多氯联苯、农药和酞酸酯等几类典型的有机污染土壤中外生菌根和丛枝菌根的作用;旨在说明利用菌根技术修复有机污染土壤是生物修复的一项重要工具,具有广阔的发展前景,为进一步研究菌根的作用以及更好地运用菌根技术奠定基础。

Abstract: Common use and large-scale production of organic compounds have aggravated soil pollution,and the traditional remediation methods have limitation in some degree.As one of mutual symbiosis formed between plants and mycorrhizal fungi,mycorrhizae can improve the ability of plants to endure the environmental stress and have great impacts on the degradation and translation of organic matters.Effects of ectomycorrhiza and arbuscular mycorrhiza on bioremediation of soils polluted by petroleum,PAHs,PCBs,pesticides and PAEs were discussed in this review.

Key words: Long-term fertilization, Soil organic matter, Density fraction, Fluvo-aquic soil
