Abstract

The effects of applying four accumulator species (Conyza canadensis, Cardamine hirsute, Eclipta prostrate and Nasturtium officinale) straws in cadmium (Cd) contaminated soil on phosphorus (P), potassium (K) and nitrogen (N) uptakes of Galinsoga parviflora were studied through the pot experiment. Five treatments were used in the experiment: control (no straw applied), and straw applied for each of the four plant species (C. canadensis, C. hirsute, E. prostrata and N. officinale). When applying the four accumulator species straws in Cd-contaminated soil, only E. prostrata straw and N. officinale straw increased the total P and K contents in roots, stems and leaves of G. parviflora compared with control, and E. prostrata straw was the best. Only applying straws of C. canadensis, C. hirsute and N. officinale increased the total N content in stems and leaves of G. parviflora compared with control, and the rank was C. canadensis straw > N. officinale straw > C. hirsuta straw > control. Therefore, only suitable applying accumulator straw could used to increase nutrient uptake of G. parviflora in Cd-contaminated soil.
