| Abstract: | One-year-old potted Ginkgo biloba L. seedlings were treated with different amounts of nitrogen (N). The results indicated that all treatments could enhance the plant height, stem diameter and leaf number of potted Ginkgo biloba L. seedlings. Furthermore, the treatment with the largest amount of N had the best effect on the seedling growth Under the same amount of N, the treatment with some bean cake fertilizer would be helpful to increase the numbers of leaves in potted Ginkgo biloba L.seedlings. |
