Study on Container Seedling Raising Technology of Cinnamomum camphora in Southern Sichuan

In order to establish a technical system suitable for container seedling raising technology of Cinnamomum camphora in southern Sichuan, this study analyzed the effects of substrate ratio, slow-release fertilizer amount and container size on the container seedling growth of Cinnamomum camphora by the factorial experimental design. The results showed that the interaction of substrate formula, slow-release fertilizer amount and container size had a significant effect on the seedling height, ground diameter and height-diameter ratio of 1-year-old Cinnamomum camphora container seedlings. The most suitable factor combination for Cinnamomum camphora container seedling cultivation in southern Sichuan was as follows: the substrate ratio was coconut bran : peat : soil = 1:2:1, the amount of slow-release fertilizer was 1 kg·m⁻³, the container size of non-woven container was 12.5 cm ×16.0 cm.
