| 摘 要： | 为控制或减少烟叶中的重金属含量,提高卷烟产品的安全性,采用盆栽和室内分析测试相结合的方法,研究重金属镉(Cd)在烤烟中的累积分布。研究结果表明,Cd在烤烟根系和茎中的含量较低,叶片中含量较高,吸收的Cd 80%以上分布在叶片中;Cd在烤烟中的迁移性较强,烤烟对Cd的耐受力较强。因此,烤烟种植时应选择Cd含量较低的土壤,防止重金属在烤烟中累积,危害吸食者。 |

| Abstract: | In order to increase the safety of tobacco products,and to control or decrease cadmium content in tobacco leaves,the accumulation and distribution of cadmium in flue-cured tobacco were studied by using pot experiment and lab analysis.The results showed that,Cd content was lower both in root and stem of flue-cured tobacco,but it was high in leaves,more than 80% of Cd was found in leaves.Because Cd has high migrantion and flue-cured tobacco is insensitive to Cd,the flue-cured tobacco should be planted in soils with low Cd to prevent Cd accumulation in tobacco leaves and hurt smokers. |
| Keywords: | cadmium flue-cured tobacco accumulation distribution |
