Effect of Container Types and Sizes on the Growth of Phoebe zhennan Seedlings

In order to explore the response mode of Phoebe Zhennan seedling growth to container types and sizes, a two-factor (container type and container size) experimental design was carried out in this study. 1-year-old Phoebe zhennan seedlings were selected as the research object, and the height of seedlings and ground diameter were measured at the end of the growing season, and the ratio of height to diameter was calculated, so as to screen the suitable container type and size for the cultivation of improved Phoebe zhennan seedlings. The results showed that the growth of seedling height was more affected by container type, while the growth of ground diameter was more restricted by container size. The seedling height and ground diameter produced by the 10 × 15 cm plastic seedling bag were higher, and the height to diameter ratio was significantly lower than that of most other types and sizes (P＜0.05). Consequently, considering the growth quality and economic benefits of seedlings comprehensively, it is recommended to choose 10 × 15 cm plastic seedling bags in actual production and application to cultivate improved varieties and strong seedlings.
