摘　　要：闽北山地多种阔叶树的对比造林试验和鹅掌楸人工林经营研究表明 ,鹅掌楸具有适应性强、早期速生等丰产特性 ,是南方基地造林的优良阔叶树种。造林后第 3年鹅掌楸即进入速生阶段 ,在较好的立地上 ,8年生时平均树高 12 .6m ,平均胸径 12 .4cm ,立木蓄积年生长量超过 16m3·hm- 2 。可利用较好的立地纯林经营 ,并根据培育目标设计不同的初植密度。在较差的立地上与桤木、木荷、杉木、建柏等混交效果较好。鹅掌楸叶大量多 。The study on species trial and plantation forest management showed that Liriodendron chinense is a good broadleaved species over the mountainous areas in south China with wide adaptability,fast growth in the early stage and high yielding.Three years after afforestation, L.chinense enters the period of fast growth.Under good site condition,the meanheight,mean DBH and volume increment of 8 year old L.chinense are 12.6 m,12.4 cm and over 16 m 3·hm -2 respectively.Good site could be used to establish pure plantation stand with moderate tree density designed according to different cultural objectives.On the poor site, L. chinense could be planted with Alnus cremastogyne, Schima superba,Cunninghamia lanceolata and Fokienia hodginsii. Because of its rich foliage and litter,both the pure or mixed plantation could obviously ameliorate the soil fertility.
