Abstract

A pot experiment was conducted to study the effects of intercropping density different density (1, 2, 3, 4 and 5) of cadmium (Cd) hyperaccumulator Galinsoga parviflora on Cd accumulation of radish. Intercropping different densities with G. parviflora decreased the growth of radish, and increased cadmium content in radish. After intercropping with G. parviflora, the Cd content in radish increased when the density of G. parviflora was not more than 3, and decreased when the density of G. parviflora was higher than 3. When the density was not more than 3, intercropping with radish increased biomass of G. parviflora, and decreased when the density was higher than 3. Intercropping with radish increased Cd content in G. parviflora. With the increase of density, the Cd exaction by roots of G. parviflora increased when the density was not more than 4, and decreased when the density was higher than 4. Therefore, in the Cd-contaminated soil, intercropping with G. parviflora could not be suitable for radish production.
