摘  要:
应用随机区组设计,在Ⅱ立地级、郁闭度为0.6的杉木林冠下进行套种黑壳楠、观光木、金叶含笑、南方红豆杉试验。结果表明:4个树种幼树的平均保存率在97.9%以上,均能正常生长。生长量大小依次为观光木﹥金叶含笑﹥黑壳楠﹥南方红豆杉,9年生树高、胸径、蓄积量,观光木分别达6.73 m、7.76 cm、20.3971 m3·hm-2;金叶含笑分别达6.17 m、7.06 cm、15.6049 m3·hm-2,观光木、金叶含笑适宜在Ⅱ立地级、郁闭度0.6的杉木林冠下生长。

摘  要:
The growth of four species,Lindera megaphylla,Tsoongiodendron odorum,Michelia foveolata and Taxus mairei,under the crown of Cunninghamia lanceolata was tested by randomized block design,the canopy density 0. 6 and with Ⅱ-class site condition. The results showed that the preserving rate of the four species juvenile trees were above 97. 9%,all can regular growing. Increment were Tsoongiodendron odorum > Michelia foveolata > lindera megaphylla > Taxus mairei,9-year height,DBH and stand volume per hectare,Tsoongiodendron odorum were 6. 73 m、7. 76 cm、20. 3971 m3·hm- 2and Michelia foveolata were 6. 17 m,7. 06 cm,15. 6049 m3·hm- 2,Tsoongiodendron odorum、Michelia foveolata were suitable to interplant under the canopy density0. 6 of C. lanceolata with Ⅱ-class site condition.
