摘　　要：对红豆树(Ormosia hosiei)容器苗与裸根苗在3种不同立地条件下进行成活率、树高和胸径生长量造林对比试验。结果表明:红豆树在不同处理间造林,成活率、6年生幼树高和胸径生长量差异极显著,立地条件与苗木类型间的互作效应在成活率和胸径上呈极显著差异,在树高上无显著性差异;采用容器苗造林成活率、6年生幼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呈极显著差异,随着立地条件变差,容器苗与裸根苗之间的造林成活率、树高和胸径生长量差距逐渐拉大,对造林成效的影响依次为:胸径>成活率>树高。Experiment on StLrvival rate, increment of height and DBH of Ormosia hosiei, with container and bare-rooted seedlings was carried out under site conditions of good, medium and poor. The result showed that it had significant differences of survival rate, increment of height and DBH of 6-year O. hosiei among different treatments. The interaction effect of site conditions with seedling types had significant difference on survival rate and DBH of O. hosiei. The survival rate, increment of height and DBH of 6-year container seedlings were greater than of that bare-rooted seedlings. There was significant difference on survival rate, increment of height and DBH of 6-year container and bare-rooted seedlings among different site conditions, and even greater with the worse of site condition. The affect factors of afforestation results were： DBH〉 survival rate 〉 height growth.
