Phytoremediation is a special technoloque of remediating contaminated soil by using the plant hyperaccumulators to remove pollutants in soil 植物修复技术是一种利用超富集植物提取污染土壤中有害物质的技术。
Phytoremediation has been regarded as a suitable technique for the pollution control of heavy metals contaminated soils 摘要随著对重金属超积累植物研究的加深，用植物提取修复技术来改良重金属污染的土壤已逐步进人实用阶段。
Screening accumulators or hyperaccumulators with large biomass and strong ability to take up environmental pollutants is the key for successful phytoremediation practices 植物修复技术能否成功实施的关键是如何筛选生物量大、对环境污染物富集能力强的积累植物和超积累植物。
Plants can accumulate heavy metals form the environment . phytoremediation of cd polluted environment is an available method . zizannia caduciflora and acrous calamus were the accumulating plants of cd 本文研究了植物菰和菖蒲对cd的富集，菰和菖蒲各器官对cd的富集能力不同。
It is commonly recognized that phytoremediation is a cost - effective , engineering - economical and environmental friendly technique , and shows great prospect in the practice of contaminated soil remediation 植物修复是一种价格低廉、易于工业化和环境友好的技术，有非常广阔的应用前景。
This paper introduces the principles , advantages , disadvantages , affecting factors and recent progress of phytoremediation and microbial remediation on pahs contaminated soil , and discusses the future research priorities of bioremediation 摘要概括介绍了多环芳烃污染土壤的植物修复、微生物修复和植物微生物联合修复的原理、优缺点、影响因素及国内外研究进展，并对生物修复的未来发展进行了展望。
Effects of cd on growth , photochmecal efficiency , chlorophyll content and net photosynthesis of canna indica linn and rumex acetosa l were studied so that the theoretical basis of phytoremediation of pollution by cd could be provided )为实验材料，研究cd胁迫对美人蕉和酸模的生长、光化学效率、叶绿素含量以及净光合强度等生理指标的影响，探讨cd对高等植物的毒害效应，以期为重金属cd污染的植物修复技术提供理论依据。
