Effects of Intercropping with Post-grafting Generation of Cosmos sulphureus on Nitrogen Uptake of Grape under Cadmium Stress
Year: 2018
Type: conference-paper
Abstract: Pot experiments were conducted to study the effects of intercropping with post-grafting generation of Cosmos sulphureus on nitrogen (N) uptake of grape under cadmium (Cd) stress. The results showed that intercropping with post-grafting generation of C. sulphureus could reduce N absorption of grape compared with grape monoculture (MG) under Cd stress. As a whole, the N content in grape were ranked in the following order: MG > intercropping with the post-grafting generation of self-rooted grafting by two same sizes seedlings of C. sulphureus (PSSG) > intercropping the post-grafting generation of self-rooted grafting by two different sizes seedlings of C. sulphureus (PSDG) > intercropping with the post-grafting generation of self-rooted grafting by the same one seedling of C. sulphureus (PSG) > intercropping with the generation of ungrafted C. sulphureus (UG). Intercropping with post-grafting generation of C. sulphureus had no significant effect on the alkaline N content in soil compared with MG under Cd stress (P > 0.05). Intercropping with UG, PSG and PSDG increased alkaline N content in soil, while intercropping with PSSG decreased alkaline N content in soil. In conclusion, Grape intercropping with post-grafting generation of C. sulphureus could improve alkaline N content in soil as a whole, but which decreased N content in grape under Cd stress.
