Effects of Intercropping with Post-Grafting Generation of Impatiens balsamina on Nitrogen Uptake of Grape Seedlings under Cadmium Stress

A pot experiment was conducted to study the effects of intercropping with post-grafting generation of Impatiens balsamina on nitrogen content in each part of grape seedlings and the alkaline nitrogen content in soil. Results showed that under cadmium stress, intercropping with post-grafting generation of I. balsamina (intercropping with I. balsamina of non-grafting, intercropping with post-grafting generation of self-rooted grafting by the same one seedlings of I. balsamina, intercropping with post-grafting generation of self-rooted grafting by the two same sizes seedlings of I. balsamina, intercropping with post-grafting generation of self-rooted grafting by the two different sizes seedlings of I. balsamina) reduced the nitrogen content in each part of the grape seedlings compared with monoculture. But all the intercropping treatment increased the soil alkaline nitrogen content compared with monoculture. In conclusion, intercropping with post-grafting generation of I. balsamina reduced the nitrogen content of grape seedlings and increasing the soil alkaline nitrogen content.
