摘  要:
[目的]研究了印度芥菜对石灰性土壤中难溶态铅的吸收、活化和积累规律。[方法]采用盆栽试验,研究了印度芥菜对石灰性土壤中难溶态Pb吸收的影响和对石灰性Pb污染土壤的修复效率。[结果]印度芥菜能够吸收石灰性土壤中难溶态铅并正常生长。印度芥菜吸收的铅80%以上累积在根部,根际与非根际土壤中DTPA提取的铅含量差异不显著。在该试验条件下,印度芥菜对土壤中铅的净化率为0.01~0.02%。[结论]印度芥菜对模拟石灰性污染土壤中难溶态Pb的净化效果不理想。

摘  要:
[Objective] The rules of uptake and activation of insoluble Pd in calcareous soil by Brassica juncea were studied.[Method] The pot experiment was carried out to study the effect of Brassica juncea on the absorption of insoluble Pb and the purification efficiency.[Result] Indian mustard could absorb insoluble Pb and grew well.Pb uptake by Brassica juncea was existed in root and higher than 80%.The difference DTPA-extractable Pb in rhizosphere and non-rhizosphere of Brassica juncea was not significant.The Pb purification rate of the soil by Brassica juncea was 0.01%-0.02% at this test condition.[Conclusion] The effect of Brassica juncea on the purification of insoluble Pb in simulated calcareous polluted soil was not ideal.
