Under certain conditions, the activation and migration of soil Cd were accelerated by the interaction of Pb and Cd and increased Cd uptake by wetland rice. The organic-bound Cd in rizhosphere decreased by 90%. These phenomena illustrates that the interaction is very important for the transformation of soil Cd fractions. Meanwhile, the interaction distinctly affected the composition of roots secretion and their coordination abilities with heavy metals, causing clear variation to Cd amount in root cortex and middle columniation.

在一定的实验条件下，Pb和Cd的交互作用促进了Cd的活化与迁移，增加了水稻地上部分对Cd的吸收，使根际土有机结合态Cd下降了90%左右，表明交互作用对Cd形态的转化是一个重要的控制因素；同时交互作用对根系分泌物的组成及其与重金属的配位能力有着明显的影响，使Pb、Cd在根系皮层和中柱中Cd的含量有明显变化。
