摘要: 为探讨镉(Cd)污染土壤对蔬菜作物的影响,以小白菜为试验材料,采用盆栽试验方法,研究了土壤含镉3,6 mg/kg对小白菜产量、小白菜食用部位Cd含量及营养元素含量的影响。结果表明:3,6 mg/kg Cd污染土壤不影响或促进小白菜植株生长,但小白菜基因型间存在很大差异;小白菜地上部Cd含量和Cd积累量随着土壤中Cd浓度的增加而显著增加,且基因型间存在显著差异。Cd影响小白菜地上部营养元素含量,这种影响依元素种类、品种及Cd处理浓度而不同。

关键词: 镉, 污染土壤, 小白菜, 营养元素

Abstract: A pot experiment indicated that Cd(3 mg/kg and 6 mg/kg) did not affect or enhanced the growth of pakchoi,there were differences among cultivars in the effects of Cd on the growth of shoots.The concentrations and accumulations of Cd in shoots were increased with increasing Cd concentrations in soil,and significant differences were exsisted among cultivars.Cd affected nutrient elements of shoots in pakchoi,and the effects of Cd on the nutrient elements were dependent on different cultivars,different Cd concentrations and different kinds of elements.

Key words: Cadmium, Pollution soil, Pakchio, Nutrient element
