摘要：Based on the selenium stress, the effects of living Pterocypsela laciniata and its straws on phosphorus (P) uptake of grape seedlings were carried out. There were some important results and showed that in parts of grape seedlings. The total P content was lower in roots than that in stems, leaves and shoot. Among five treatments, there was quite different about the total P content. Compared to grape seedlings monoculture, living P. laciniata and its straws could significantly increase the total P content in parts of grape seedlings. Among them, applying the leaf straw of P. laciniata MG. The available P content in soil was a little changed in relation to the total P content in plants. Applying P. laciniata straws also could increase the available P content. On the contrary, grape seedlings intercropping with P. laciniata seedlings decreased the available content, compared to the monoculture. In a word, living P. laciniata and its straws was good for the growth of grape seedlings and improved the P uptake in plants.
