摘　　要：在好、中、差3种立地条件下,选用木荷Schima superba容器苗与裸根苗进行成活率、树高和胸径生长量造林对比试验。结果表明:采用不同处理木荷成活率、6年生树高和胸径生长差异极显著,立地条件与苗木类型间的互作效应也极显著。采用容器苗造林成活率、6年生树高和胸径生长量极显著大于裸根苗造林;不同立地条件下造林成活率、6年生树高和胸径生长量表现为:好的立地条件>中等的立地条件>差的立地条件,差异达极显著;经造林成本比较,容器苗比裸根苗造林成本低14.6%。研究认为,采用容器苗造林,木荷成活率高,生长量大,造林成本低,防护效果较好,在绿化造林中值得推广。Comparisons of survival rate, tree height, and diameter at breast height （DBH） growth of Schima superba using containerized and bare-root planting stock were conducted for good, medium, and poor site conditions. Results showed an interaction between site condition and seedling type was highly significant （P〈0.01）. Survival rate, 6-year-old tree height, and DBH growth for containerized seedlings were significantly greater （P〈0.01）than bare-root stock. Also, in good sites, survival rate, 6-year-old tree height, and DBH growth were significantly higher （P〈0.01）than medium sites, which in turn were significantly higher （P〈0.01）than poor sites. Moreover, utilizing containerized seedlings cost 14.6% less than bare-root planting stock. We concluded that for artificial regeneration, containerized planting was advantageous as it had higher survival and growth rates and offered better protection at lower costs.
