摘　　要：利用不同切根处理的米槠容器苗和裸根苗开展杉木米槠混交林造林试验,造林5年后调查测定米槠保存率、生长量和形质性状,以分析米槠容器苗造林效果。结果表明:利用芽苗切根培育的容器苗造林的米槠成活率、保存率、平均树高、平均胸径均显著高于实生裸根苗造林,单株、单位面积立木材积极显著高于实生裸根苗造林,形质性状差异不显著;胚根切根培育的容器苗的米槠成活率、保存率及生长量介于芽苗切根容器苗和实生裸根苗造林二者之间。鉴于米槠的特性,建议在米槠人工造林时,选择经芽苗切根处理的容器苗造林。The container planting and bare root seedlings of Castanopsis fallow were used to carry out the afforestation experiment of mixed Cunninghamia lanceolata mixed forest.After 5 years of afforestation,the preservation rate,growth and quality characters of Castanopsis were investigated and analyzed.The results showed that the survival rate,preservation rate,average tree height and average DBH of container seedlings cultivated by bud seedling root cutting were significantly higher than those of bare root seedlings,and the standing wood per plant and unit area was significantly higher than that of bare root seedlings;The survival rate,preservation rate and growth of container seedlings cultivated by radicle cutting are between bud seedling,root cutting container seedling and seedling bare root seedling.In view of the characteristics of Castanopsis carlesii,it is suggested that container seedlings treated by bud seedling and root cutting should be selected for afforestation.
