Abstract

In order to study the effects of grape seedlings intercropping with hyperaccumulators on five forms of cadmium in soil, a pot experiment was conducted to to study the effects of grape seedlings intercropping with Galinsoga parviflora, Siegesbeckia orientalis, Solanum nigrum and Crassocephalum crepidioides, respectively on exchangeable, bound to carbonates, bound to Fe-Mn oxides, bound to organic matter and residual cadmium contents. The results showed that compared with monoculture, only grape intercropping with G. parviflora could significantly increase the content of residual Cd, which is conducive to the fixation of Cd in the soil and may reduce the plant's enrichment of Cd. Therefore, grape seedlings intercropping with G. parviflora could benefit for the decline of bioavailability of Cd.
