檫树人工造林的历史虽较短,但实践证明,即使在自然条件较差的丘陵区,其效果也是好的。例如,安乡县黄山头林场丘陵山地上的13年生檫树(初植每亩74株,现在每亩保存57株),平均胸径15.6厘米,平均树高14.2米,每亩立木蓄积7.08立方米。我所低丘红壤上13年生的檫树(初植每亩107株,造林后4年起陆续间伐,现在每亩保存66株),平均胸径13.9厘米,平均树高12米,每亩立木蓄积6.39立方米。上述檫林的造林整地及抚育管理均属一
Although the history of artificial tree planting is rather short, practice has proved that the effect is good even in the hilly areas with poor natural conditions. For example, the 13-year-old Sawgrass Tree on the hillside of the Forest Farm in Huangshantou, Anxiang County (initial planting of 74 plants per mu and 57 plants per acre), with an average diameter of 15.6 cm and an average tree height of 14.2 meters and 7.08 cubic meters per mu . On the hilly red soil, 13-year-old balsam tree (initial planting of 107 plants per mu, four years after afforestation, successive thinning, 66 plants per mu), average diameter of 13.9 cm, average height 12 m, 6.39 cubic meters. The above-mentioned forest afforestation and tending management belong to one
