开展了毛红椿(Toona ciliata var. pubescens)、光皮桦(Betula luminifera)、乳源木莲(Manglietia yuyuanensis)、杂交马褂木(Liriodendron chinense.× L.tulipifera)、桤木(Alnus cremastogyne)和南酸枣(Choerospondias axillaria)6种优良阔叶用材树1 666、2 500、3 333株/hm~23种造林密度试验,对4年生林分的观测结果显示:造林密度为1 666株/hm~2桤木林分胸径显著高于造林密度为3 333株/hm~2和2 500株/hm~2的桤木林分;造林密度对其它各树种各生长指标的影响不显著.光皮桦和桤木的生长较快,乳源木莲生长最慢.研究认为,以培育中、大径材为目的的用材林,光皮桦、桤木初植密度宜定在1 666株/hm~2;毛红椿、杂交马褂木、南酸枣初植密度以1 666株/hm~2和2 500株/hm~2为宜,乳源木莲则以2 500株/hm~2和3 333株/hm~2为宜.
Effect of Plantation Density on Early Growth of Six Broad-leaf Tree Species
Experiment was carried out on plantation with different density of Toona ciliata var. pubescens, Betula luminifera, Manglietia yuyuanensis, Liriodendron chinense × L. tulipifera, Alnus cremastogyne and Choerospondias axillaria. Investigation on 4-year A. cremastogyne stands showed that DBH in plantation with density of 1 666 trees/ha was significantly higher than that in the plantations with 3 333 and 2 500 tree/ha, while growth of the left tree species had no evident relation with plantation density. B. luminifera and A. cremastogyme grew faster than other species, while M yuyuanensis grew the slowest. The experiment concluded that it was suitable for B. luminifera and A. cremastogyne to be planted with density of 1 666/ha, for T. ciliata, L. chinense × L. tulipifera and C. axillaria with density of 1 666 or 2 500/ha, and for M. yuyuanensis with 2 500 or 3 333/ha.
