Analysis of Planting Experiment and Growth Effect of Broad Leaved Species

The planting experiment of industrial raw material forest of 10 broad leaved species of Alnus trabeculosa,choerospondias axillaries,Toona sinensis and styrax tonkinensis was carreid out in Jiangle National Forest Farm.The adaptability and growth condition in 9 years were analyzed.The results showed that 2 species of Alnus trabeculosa and styrax tonkinensis which could be used as industrial raw material forest within short period were popularized in the locality. Growth effect on the tree height and breast diameter and volume of 2 afforestation with different densities were different as different species. Optimum density should be adopted to plant according to different species when cultivate industrial raw material forest within short period.
