Abstract

The effects of intercropping with accumulator species (Capsella bursa-pastoris, Cardamine hirsute and Galium aparine) on phosphorus (P) and potassium (K) uptakes of Galinsoga parviflora under cadmium (Cd) contaminated soil were studied through the pot experiment. Seven treatments were used in the experiment: monoculture of G. parviflora, monoculture of C. bursa-pastoris, monoculture of C. hirsute, monoculture of G. aparine, G. parviflora intercropping C. bursa-pastoris, G. parviflora intercropping C. hirsute and G. parviflora intercropping G. aparine. When intercropping with three accumulator species, the total P and K contents in roots and shoots of G. parviflora were ranked as: G. parviflora (intercropping with G. aparine) > G. parviflora (monoculture) > G. parviflora (intercropping with C. hirsute) > G. parviflora (intercropping with C. bursa-pastoris). When intercropping with G. parviflora, the total P and K contents in roots and shoots of C. bursa-pastoris increased, but the total P and K contents in roots and shoots of C. hirsute and G. aparine decreased compared with monoculture respectively. Therefore, intercropping with G. aparine could used to increase nutrient uptake of G. parviflora in Cd-contaminated soil.
