| 摘 要： | 将污染的土壤进行室内栽培种植试验,通过施加不同浓度的EDTA溶液,研究不同玉米部位对重金属砷、镉、镍、铅的富集情况。结果表明:土壤中施加低浓度EDTA时,可使玉米中As、Ni、Cd、Pb的总含量呈一定的下降趋势。随着EDTA浓度的增加,玉米中As、Ni、Cd、Pb的含量均呈增加的趋势,不同部位吸收特征有所不同。 |

| Abstract: | The accumulation of As,Ni,Cd and Pb in different parts of maize was studied with the indoor cultivation experiments on contaminated soil,when different concentrations of EDTA solution were added.The results show that the total content of As,Ni,Cd and Pb in maize was decreased slightly when low concentration of EDTA was applied in the soil.With the concentration of EDTA increased,the content of As,Ni,Cd and Pb in maize was increased.Different absorption characteristics were shown in different parts of maize. |
| Keywords: | soil heavy metal pollution maize accumulation |
