| 摘 要： | 通过烤烟盆栽试验,研究了在土壤-烤烟系统中As、Cd、Pb 3种重金属复合污染的交互作用以及相关性。结果表明:在受重金属污染的土壤上,烤烟的株高、叶片数、生物量均低于对照,且各处理烟株生物产量的减少幅度表现为:As+Cd+Pb>Cd+Pb>As+Pb>As+Cd>As>Pb>Cd;Cd在烟株中的迁移能力大于As和Pb;土壤中的Pb、As对Cd在烟株中的积累均表现为协同作用,土壤中的Cd对Pb在烟株中的积累产生拮抗作用,As和Pb在土壤中则产生沉淀钝化作用;烤烟植株中的As、Cd含量分别与土壤中的As、Cd含量显著或极显著相关,而烟株体内的Pb含量除与土壤中的Pb含量极显著相关外,还与土壤中的As含量显著相关。 |

| Abstract: | The interaction and correlation of heavy metal(As,Cd and Pb) compound pollution in soil-flue-cured tobacco system were studied through pot experiments.The results indicated that: in the soil polluted by these three kinds of heavy metal,the plant height,leaf number and biomass of flue-cured tobacco were all lower than those of the check,and the decrease in the biomass of tobacco plant in various treatments exhibited the following sequence: As+Cd+Pb>Cd+Pb>As+Pb>As+Cd>As>Pb>Cd.Cd had stronger mobile ability in tobacco plants than As and Pb.The content of both Pb and As in the soil was consistent with the accumulation of Cd in tobacco plants.The Cd content in the soil had an antagonistic effect on the accumulation of Pb in tobacco plants.As and Pb in the soil could occur deposition and passivation.The content of As and Cd in tobacco plants showed significant or very significant correlation with the content of As and Cd in the soil,while the Pb content in tobacco plants not only showed very significant correlation with the Pb content in the soil,but also revealed significant correlation with the As content in the soil. |
