摘    要:采用盆栽方法研究在 Cd、Pb、Zn污染土壤上 ,石灰和泥炭配施对春小白菜吸收重金属元素 (Cu、Zn、Cd、Pb、Fe、Mn )的影响 .结果表明 :石灰、石灰加低量泥炭、石灰加高量泥炭处理均显著抑制小白菜对重金属的吸收 ,泥炭对石灰的效果没有负面影响 .土壤有效态 Zn、Cd、Pb含量与土壤 p H呈极显著的负相关 (R2为 0 .78* * * -0 .84* * * ) ,与小白菜茎叶 Cd、Pb、Zn的含量则呈极显著正相关 (R2 为 0 .45 * *-0 .86* * *) .而茎叶 Cd、Pb、Zn的含量与土壤 p H呈极显著的二项式相关 (R2 为0 .87* **-0 .95 * * *) ,茎叶 Zn、Cd、Pb的含量先是随 p H的升高而下降 ,而当 p H升到 6.7左右后 ,其含量又所有回升

关 键 词:重金属污染土壤  石灰  泥炭  小白菜

Abstract:Effect of lime and peat application on the uptake of Cd, Pb, Zn, Cu, Mn and Fe of pakchoi ( Brassica chinensis ) was studied by pot experiment in cadmium, lead and zinc contaminated soil. Lime, lime with low peat addition, lime with high peat addition all significantly inhibited the uptake of heavy metals by pakchoi. The available heavy metals of Cd, Zn and Pb in soil significantly negatively correlated with soil pH ( R 2: 0.78 *** -0.84 *** ). The contents of Cd, Pb and Zn in pakchoi positively correlated with their available contents in soil ( R 2: 0.45 ** -0.86 *** ). Significant binomial correlation existed between the contents of Cd, Pb and Zn in pakchoi and soil pH ( R 2: 0.87 *** -0.95 *** ). Zn, Cd and Pb concentrations in pakchoi decreased as soil pH increased, while soil pH higher than 6.70, Zn, Cd and Pb concentrations increased slightly.
Keywords:heavy metal contaminated soil  lime  peat  pakchoi
