摘要：A pot experiment was conducted to study the effect of intercropping S. nigrum, tomato and eggplant on the phosphorus content under cadmium stress. The results showed that the content of phosphorus in roots, stems, leaves and aboveground parts of S. nigrum (intercropping with tomato) was increased by 6.15%, 76.98%, 4.90% and 39.71%, respectively. The phosphorus content in roots, stems, leaves and aboveground parts of tomato (intercropping with S. nigrum) decreased by 10.64%, 26.85%, 7.73% and 19.08%, respectively, after intercropping of S. nigrum and tomato. The intercropping of S. nigrum and eggplant increased the content of phosphorus in roots, stems, leaves and aboveground parts, and the content of phosphorus in roots, stems, leaves and aboveground parts of S. nigrum (intercropping with eggplant) increased by 9.57%, 130.47%, 51.47% and 91.87%, respectively. The phosphorus content in roots, stems, leaves and aboveground parts of eggplant (intercropping with S. nigrum) increased by 0.85%, 8.83%, 66.77% and 33.12%, respectively. Therefore, intercropping of S. nigrum and eggplant can increase the phosphorus content of both and increase their absorption of soil nutrients.
