The effects of rape rootstock on phosphorus (P) and potassium (K) uptake and soil enzyme activity of post-grafting generation of Capsella bursa-pastoris under cadmium (Cd) stress was investigated through two pot experiments. Three treatments were used in the experiment: ungrafted (UG), post generation of self-rooted grafting by the two C. bursa-pastoris seedling (PSG) and post generation of grafting on the rootstock of rape (PRG). In high and low soil Cd concentration experiments, the grafting increased P and K contents in roots and shoots of post-grafting generation plants of C. bursa-pastoris compared with UG under Cd stress. The P and K contents in plants were ranked as PRG > PSG > UG. In two experiments, the soil available P and K contents were increased by post-grafting generation of C. bursa-pastoris, which were ranked as: PRG > PSG > UG. The post-grafting generation of C. bursa-pastoris enhanced soil sucrase and soil catalase activities in two experiments. The soil urease activity of PSG enhanced compared with UG, but the soil urease activity of PRG decreased. Therefore, grafting could used to increase nutrient content and enhance soil enzyme activity in post generation of C. bursa-pastoris for the phytoremediation of Cd.
