Abstract: To screen out the containerized seedling scheme suitable for the growth and development of Ficus concinna var. subsessilis, Cinnamomum japonicum and Schima superba, the factorial design was used to study the effects of the matrix, container specs and slow release fertilizer dosage on the growth of 2- year- old container seedlings of Ficus concinna var. subsessilis, Cinnamomum japonicum and Schima superba. Studies showed that the matrix ratio had no obvious effect on the growth of the 2-year-old container seedlings of the three tree species, but the growth of the container seedlings of Ficus concinna var. subsessilis and Cinnamomum japonicum was sensitive to the matrix. The container spec had a significant effect on the growth of the container seedlings, and the best effect was achieved by 18 cm× 18 cm non-woven container bag. The seedling height and ground diameter of the Ficus concinna var. subsessilis container seedlings increased significantly with the increase of slow-release fertilizer application. Cinnamomum japonicum and Schima superba had the highest seedling height and ground diameter growth when the slow-release fertilizer was 2.0 kg/m3 and the growth decreased when the slow release fertilizer dosage exceeded 2.0 kg/m3. The interaction between various factors basically reached significant level. Comprehensively considering the main effect and interaction effect of all factors, three to five kinds of optimization scheme for containerized seedlings were selected for afforestation of the tree species.
