摘　　要：以田林麻竹、龙竹、马来甜龙竹、吊丝球竹,壮绿竹、撑绿杂交竹6号、撑绿杂交竹30号的容器扦插苗为研究材料,在南宁市林业科学研究所营造试验林,研究其生长情况。结果表明:造林6个月后,7种大型丛生竹容器扦插苗的造林成活率在50%-93.4%,吊丝球竹和撑绿杂交竹6号的造林成活率较高,田林麻竹的成活率最低;撑绿杂交竹30号的长势最好,龙竹和壮绿竹的长势较差;新竹数量与母竹萌芽数量呈正相关;新竹地径均与母竹地径、萌芽枝条数量和长度正相关。A experimental forest was built in Nanning Academy of Forestry by taking the container cuttage seedlings of Dendrocalamus latiflorus,D.giganteus,D.aspera,Bambusa beecheyana,B.vadidus,B.pervariabilis×Dendrocalamopsis grandis 6#,B.pervariabilis×Dendrocalamopsis grandis 30#as the research materials.The results showed that after 6 months planting,the cuttings survival rate of these 7 large clustered bamboo containers ranged from 50%to 93.4%.The survival rate of Bambusa beecheyana and Bambusa pervariabilis×Dendrocalamopsis grandis 6#was the highest,and the survival rate of Dendrocalamus latiflorus of Tianlin was the lowest.The growth of Bambusa pervariabilis×Dendrocalamopsis grandis 30#was the best,while the growth of D.giganteus and B.vadidus were relatively poor.The number of new-born bamboos was positively related to that of shoots of mother bamboo,the diameter of new-born bamboos was positively related to diameter,sprout number and length of the mother bamboo.
