摘要
采用盆栽试验研究了重金属镉(Cd)、铅(Pb)复合污染土壤中添加磷对草莓生长和重金属累积的影响。结果表明,重金属Cd、Pb污染降低了草莓产量和维生素C含量,且不同浓度处理对草莓产量变化及吸收重金属的影响有很大不同,但在不同浓度处理下,Cd、Pb在草莓各组织的累积量均为根部>茎叶部>果实;添加磷肥后不仅能显著降低Cd、Pb对草莓产量和品质的影响,还能降低Cd、Pb在草莓各组织中的累积。因此,添加磷肥在重金属Cd、Pb复合污染土壤修复方面具有较大的应用潜力。
A pot experiment was conducted to study the effects of phosphorus（P）on the growth and uptake of heavy metals of strawberry grown in the soil contaminated by Cd and Pb.The results showed that the yield and vitamin C content of strawberry were decreased by the pollution of heavy metals,and a significant change was observed in yield and uptake of heavy metal under different Cd and Pb polluted levels.Moreover,different tissues of strawberry had different capability in accumulating heavy metals which was in the order of rootstem and leaf fruit,even under different treatment.Applying P fertilizer could not only reduce the impacts of Cd and Pb on the growth and quality of strawberry,but also decrease the contents of Cd and Pb in all tissues significantly.In general,P has a great application potential to remediate Cd and Pb contaminated soil.
