摘要: 随着工农业技术的快速发展，土壤Cd等重金属污染问题日趋严重，对重金属污染土壤的修复亦成为全球所关注的热点之一。植物修复因成本低以及无二次污染等优点，成为治理重金属污染的主要手段之一。植物根际促生菌(Plant Growth Promoting Rhizobacteria, PGPR)是一类生长在植物根系影响土壤范围内的微生物，在植物修复重金属污染土壤中发挥着重要的作用。本文简述了我国Cd土壤污染的现状及危害，土壤污染修复方法及各自的优缺点，重点阐述了PGPR影响植物修复重金属Cd污染土壤的机制，并对其研究前景进行了展望。
Abstract: With the rapid development of industrial and agricultural technology, the pollution of Cd and other heavy metals in soil is becoming more and more serious. The remediation of heavy metal contaminated soil has become one of the research hotspots at home and abroad. Phytoremediation has become one of the main methods to control heavy metal pollution because of its low cost and no secondary pollution. Plant Growth Promoting Rhizobacteria (PGPR) is a kind of microorganism growing in soil affected by plant roots, which plays an important role in phytoremediation of heavy metal contaminated soil. In this paper, the status and harm of Cd soil pollution in China, soil pollution remediation methods and their advantages and disadvantages were summarized. The mechanism of PGPR affecting the phytoremediation of Cd contaminated soil was emphasized, and the research prospect of PGPR was also prospected.
