摘　　要：采用随机区组试验设计方法,连续3年监测9种大型丛生竹造林后的生长情况,为选择适应广西北部地区生长的大型丛生竹提供理论依据。结果显示:在9个竹种中竹丛立竹总量(3年合计)较多的是融水麻竹(21株/丛)、撑绿杂交6#(15.8株/丛)和田东大竹(15.4株/丛);竹丛平均立竹胸径(3年平均值)较大的是麻竹(7.87 cm)、马来甜龙竹(7.76 cm)和壮绿竹(7.41 cm);竹丛立竹高度(造林后第3年)较高的是壮绿竹(13.2 m)、麻竹(12.82 m)、撑绿杂交6#(12.2 m)。综合比较各竹种的立竹量、胸径和高度3个生长指标,其生长表现优劣排序为:融水麻竹>麻竹>撑绿杂交6#>壮绿竹>马来甜龙竹>田东大竹>吊丝球竹>大绿竹>撑绿杂交30#。Using a randomized block experimental design method,the growth of 9 species of large sympodial bamboo species after afforestation had been monitored for 3 consecutive years,in order to provide a theoretical basis for selecting the species of large sympodial bamboo suitable for the condition in the north area of Guangxi.The results show that among the 9 bamboo species,Dendrocalamus latiflorus var.Rongshuiensis,Bambusa pervariabilis×D.daii 6#and D.tiandongensis(sp)have the highest culm number per clump(total for 3 years),which are 21.0,15.8 and 15.4 culms per clump,respectively;D.latiflorus,D.asper and D.valida have the highest DBH(mean value of 3 years),which are 7.87,7.76 and 7.41 cm,respectively.At the third year of growth,D.valida(13.2 m),D.latiflorus(12.82 m)and B.pervariabilis×Dendrocalamopsis daii 6#(12.2 m)show higher culm height.The overall growth of 9 bamboo species can be ordered from strong to weak as D.latiflorus var.rongshuiensis>D.latiflorus 6><1d75><>B.pervariabilis×D.daii 6#>D.valida>D.asper>D.tiandongensis(sp.)>D.beecheyana>D.daii>B.pervariabilis×D.daii 30#after comparing the three growth indicators of culm number,DBH and culm height of the 9 species.
