This experiment is to explore whether one hyperaccumulator shows the strongly accumulative capacities for low or insoluble Cd compounds in soil. Soil potting experiment was conducted to analyze the accumulation capacity of Solanum nigrum L. for 10 different Cd compounds under two levels. The results clearly indicated: The Cd concentrations of shoots and roots were very high for different Cd compounds in soils even with low or insoluble Cd compounds compared with easily soluble Cd in the treatments of soil contaminated with Cd at different concentrations. Furthermore, the EFs and TFs were all larger than 1 either. Based on the results, although the bioavailabilities of some Cd compounds in soil were lower, S. nigrum’s ability to accumulate them was still very strong. Phytoremediation may be widely used to treat with soil contaminated by different cadmium compounds. In addition, the total Cd content is also very important in evaluating the risk of Cd contamination in soil. Thus, phytoextraction is promising.

这项实验旨在探讨一种超蓄积剂是否对土壤中的低或不溶性Cd化合物具有较强的累积能力。进行了土壤盆栽实验，分析了茄茄在两个水平下对10种不同Cd化合物的累积能力。结果清楚地表明：在不同浓度的Cd污染的土壤处理中，即使是低或不溶的Cd化合物，土壤中不同Cd化合物的芽和根的Cd浓度也很高。此外，EF和TF均大于1。根据结果​​，尽管土壤中某些Cd化合物的生物利用度较低，但黑链霉菌累积它们的能力仍然非常强。植物修复可广泛用于处理受不同镉化合物污染的土壤。此外，总Cd含量对于评估土壤中Cd污染的风险也非常重要。因此，植物提取是有前途的。
