摘　　要：对闽清美菰国有林场的6年生檫树人工林幼林生长表现进行调查测定,结果表明,6年生时的林分树高、胸径、单株材积、枝下高和冠幅的总体均值分别为5.60m、7.12cm、0.01456m^(3)、2.15m和3.45m,个体间的生长表现存在较大差异;树高、胸径和单株材积在不同立地间的差异均达到了极显著水平,以山底或阳坡的生长相对较好。因此,檫树速生丰产林营建时应选择阳坡或山底造林为宜。The growth performance of young forest of 6-year-old Sassafras tsumu plantation under different site conditions in Meigu State-owned Forest Farm in Minqing was investigated and analyzed. The results showed that the overall average value of tree height, diameter at breast height, individual volume, under-branch height and crown width of 6-year-old Sassafras tsumu plantation were 5.60 m, 7.12 cm, 0.01456 m^(3), 2.15 m and 3.45 m respectively, and there were great differences in growth performance among individuals. The differences of tree height, diameter at breast height, individual volume, under-branch height and crown width among different site conditions have reached extremely significant level, and the growth of Sassafras tsumu planted on the bottom of the mountain or sunny slope were relatively better. Therefore, to build fast-growing and high-yielding Sassafras tsumu forest, it is best to plant them on sunny slope or at the bottom of mountain.
