Abstract

The effects of intercropping different density (1, 2, 3, 4 and 5) of cadmium (Cd) hyperaccumulator Galinsoga parviflora on cadmium accumulation of soybean were investigated through pot experiment. The results showed that intercropping with 1 G. parviflora seedling increased biomass of soybean compared with monoculture, and decreased when intercropping with 2, 3, 4 and 5 G. parviflora seedlings. Intercropping with different density of G. parviflora decreased Cd content in soybean compared with monoculture, and the more number of G. parviflora, the lower Cd content in soybean. When the density was not more than 3, intercropping with soybean increased biomass of G. parviflora, and decreased Cd content in G. parviflora. Intercropping with soybean increased Cd extraction by G. parviflora. Therefore, the best density of G. parviflora to intercropping with soybean was 1, which could be used in the Cd-contaminated soil for the phytoremediation.
