摘要
叙述了植物修复基本内容,重点介绍了基因技术在植物修复中的应用。文章认为,与传统的修复技术相比,污染土壤植物修复技术由于具有成本低、不破坏环境、保护人类健康和易为大众接受等优点而引起了人们极大的关注,但是,应用于修复的植物往往植株矮小、生长速度慢,近年来,国外出现了将基因技术应用到植物修复中的研究,能有效地克服上述缺点。将基因技术应用于植物修复将是今后该领域研究的一个重要方向。
Soil pollution by heavy metals has become a global problem and urgently needs to be solved. Compared with traditional technology for recovery of polluted soil by heavy metals, phytoremediation technology exhibits such advantages as lower cost, protecting environment and easy acceptance to public, facilitating much attention from scientific field. The present paper describes in detail about phytoremediation of type, mechanism of the technology, advantage and disadvantage, application of gene technology in improving remediation ability and so on. It may be suggested that applying gene technology be an important aspect of phytoremediation.
