摘要
土壤重金属污染影响粮食安全生产,利用植物修复重金属污染土壤是一种比较有应用前景的技术。盆栽试验的结果表明影响植物吸收重金属的因素除植物自身外,还有土壤pH、有机质、粘粒含量等,并进一步探讨了植物修复在实际应用中存在的问题和发展前景。
Soil pollution by heavy metal may affect on secriuty of food. The use of phytoremediation is a promising technology. The result showed that the factors of heavy metal absorption by plant such as soil pH,clay,organic carbon and plant self. There exist problems in the practical application of phytoremediation and explore the prospects for its development.
