【 摘 要 】

A pot experiment was conducted to study the effects of grape intercropping with Post-Grafting Generation of Cosmos sulphureus and monoculture on Total P content in grape roots, stems, leaves and available Phosphorus (P) content in soil under Cadmium (Cd) stress. The result showed that: All the intercropping patterns declined the contents of total P in grape roots and the contents of soil available P obviously. Intercropping with UG, PSG, PSDG and PSSG had different effects on the content of total P in grape stems and the contents of total P in grape leaves. Intercropping with PSSG increased the contents of total P in grape stems and leaves. Intercropping with UG and PSG decreased the contents of total P in grape stems and leaves. Therefore, intercropping with PSSG could increase grape P content under Cd stress.
