| Abstract: | Paulownia seedlings were cultivated by 3 kinds of methods,shoot-cutting, root-cutting and reserved root in nursery.Under same management, the order of annual height growth and bio-output is shoot-cutting seedling, reserved root seedling, root-cutting seedling, and the order of annual diameter growth was reserved root seedling, shoot-cutting seedling, root-cutting seedling. Meanwhile,the annual growth and development rules of the seedlings were analyzed.It is suggested that different management measures should be used in different breeding process. |
