【摘要】 植物修复作为一种原位修复方法,因其投入成本低、拥有良好的经济效益和生态协调性等优点而成为国内外研究热点,在重金属污染农田实地得到广泛应用。本文综述施肥农艺措施强化重金属污染土壤植物修复以及对土壤-植物系统影响的研究进展,如土壤重金属含量和生物有效性的影响等,以便进一步提高植物修复效率,为今后规模化修复重金属污染农田土壤提供参考。更多还原

【Abstract】 Phytoremediation,as a method of in situ repair,has been a research hot spot at home and abroad,not only for the low investment cost,but also the good economic efficiency and ecological coordination and other advantages,which has been widely used to control the heavy metal pollution in agricultural fields.This article focuses on an overview research of phytoremediation in soil contaminated by heavy metals,and effects of fertilizer on soil bioavailability of heavy metals,while agricultural fertilizers measures were adopted to strengthen the remediation effect,then to further improve the efficiency of phytoremediation,and provide a reference for large-scale restoration of soil which contaminated by heavy metals in the future.更多还原
