摘要：To investigate the effects of intercropping and applying Pterocypsela laciniata straws on potassium uptake of grape seedlings, this pot experiment was conducted to set up five treatments under selenium stress. From the results, the content of total K in parts of plants was different. In plants, the content in leaf was higher than that in root or stem. Among five treatments, applying P. laciniata straws always decreased the total K content in plants. Furthermore, intercropping with P. laciniata seedlings could increase the content in stem, leaf and shoot of grape seedlings. So the results showed that applying root, stem and leaf straws of P. laciniata could not improve nutrient accumulation or the growth of grape seedlings. But for the available K content, it was on the increase by intercropping and applying straws. Among them, applying stem straw of P. laciniata made the content higher. Although there was higher available K content in soil by applying straws, the total K content in plants was lower. Thus, applying P. laciniata straws was not effective on the growth of grape plant.
