| Abstract: | Afforestation tests including eight tree species were carried out in three types of stands in Raoping, Chaozhou. The results showed that Acacia mangium, Choerospondias axillaris, Swietenia mahagoni and Toona ciliate grew fast and well, with average annual ground diameter growth (GDG) of 3.17, 3.03, 2.34, 2.02 cm, height growth (HG) of 136.1, 122.9, 91.3, 87.6 cm, and crown width growth (CWG) of 59.5, 95.9, 49.8, 57.1 cm, respectively. Bischofia polycarpa, Liquidambar formosana and Cinnamomum camphora exhibited medium growth rate, with average annual GDG of 1.58, 1.61, 1.33 cm, HG of 67.7, 57.1, 49.3 cm, and CDG of 19.6, 20.2, 49.3 cm, respectively. Michelia chapensis grew relatively slowly, with average annual GDG of 1.05 cm, HG of 30.4 cm, and CDG of 11.9 cm, which was not suitable for forest transformation in East Guangdong. |
