Abstract
A pot experiment was conducted to study the effects of intercropping with post-grafting generation of Impatiens balsamina on phosphorus (P) uptake in grape roots, stems, leaves and available P content in soil under cadmium (Cd) stress. In the experiment, four grafting treatment [ungrafted (UG), self-rooted grafting by the same one seedling (PSG), self-rooted grafting by two different sizes seedlings (PSDG) and self-rooted grafting by two same sizes seedlings (PSSG)] were used to intercrop with grape seedlings. The result showed that intercropping with PSG significantly increased the content of total P in grape roots and stems, but other treatments all reduced it. The content of total P in grape leaves for the treatment of intercropping with PSDG was 24.36% higher than the monoculture and other treatments reduced it. The treatment of intercropping with UG significantly increased the content of soil available P. Therefore, under Cd stress, intercropping with post-grafting generation of I. balsamina has an impact on grape content.
