Abstract

A pot experiment was carried out to study the effects of intercropping with four cadmium (Cd) hyperaccumulator plants (Galinsoga parviflora, Sigesbeckia orientalis, Solanum nigrum, Crassocephalum crepidioides) on nutrient uptake of grape seedlings under Cd stress. When grape seedlings intercropped with G. parviflora, S. orientalis, S. nigrum and C. crepidioides, the total nitrogen (N), total phosphorus (P) and total potassium (K) contents in grape seedlings decreased compared with the monoculture under Cd stress. Grape intercropped hyperaccumulator plants had no significant effects or reduced the soil alkali soluble N, soil available P and soil available K concentrations. Therefore, intercropping with hyperaccumulator plants decreased the nutrient absorption of grape seedlings under Cd stress.
