| 摘 要： | 采用盆栽试验，研究3种改良刺对减少烟草吸收土壤重金属的效应。烟草生长在外源添加重金属达Pb300mg kg^-1和Cd 0.1mg kg^-1的污染土壤上，通过添加3种土壤改良剂，测定分析烟草在不同生长时期不同部位的生物量及重金属含量，探讨3种改良剂埘减少烟草吸收土壤重金属的效果。结果表明：Pb的转移系数小于Cd，说明这两种重金属在烟草体内的迁移能力是Cd〉Pb；与对照处理相比，所有修复剂处理的土壤重金属残留量较多；3种改良剂均在不同程度上减少了烟草不同部位重金属（Cd和Pb）的含量，且增加了烟草的生物量，都起到了一定的改良效果，本试验得到改良剂优劣顺序为：凹凸棒土〉骨粉〉活性炭。 |

| Abstract: | Pot experiments were carried out to evaluate effects of soil amendments on heavy metal uptake and distribution in different organs of tobacco plants,which were planted in soil containing Pb 330 mg kg~(-1) and Cd 1 mg kg~(-1) of extraneous sources.Three different kinds of soil amendments were applied separately,Pb and Cd contents in and biomasses of different parts of the plants during different growth periods were investigated to determine effects of the amendments on heavy metal uptake by the tobacco.The results show that the translocation factor(TF) of Pb is lower than that of Cd,indicating that Cd in tobacco moved more easily than Pb.Cd in the tobacco leaves is more harmful to human health than Pb;Compared with control,pots treated with amendments had more Cd and Pb left in the soil,suggesting that all the three kinds of soil amendments more or less reduced Cd and Pb contents in different parts of the tobacco plants,and increased biomass of the tobacco.Therefore,they had positive effects on tobacco growth and reduction of Pb and Cd uptake by tobacco.Among all the amendments,attapulgite was the best modifier,and bone powder was better than activated carbon. |
