摘要
本研究以8种丛生竹的容器扦插苗或竹蔸苗为研究材料,在南宁市林业科学研究所营造试验林,研究其造林16个月后的竹丛结构及相关性。结果表明:(1)平均立竹量较大为绿竹(7.37株)、勃氏甜龙竹(5.75株)和撑绿杂交竹30号(4.00株);(2)竹丛平均立竹胸径较粗为田林麻竹(4.66 cm)、勃氏甜龙竹(4.63 cm)和撑绿杂交竹30号(3.77 cm);(3)竹丛高度较高为勃氏甜龙竹(7.12 m)、田林麻竹(6.41 m)、绿竹(6.13 m)、撑绿杂交竹30号(6.12 m)和吊丝球竹(6.12m);(4)勃氏甜龙竹的立竹量、立竹胸径和竹丛高度均表现较好,因此生长最好;(5)除马来甜龙竹外,其余7种丛生竹的立竹量越大,竹丛高度越高;绿竹的立竹量越大,立竹胸径越大;撑绿杂交竹30号和壮绿竹的立竹量越大,立竹胸径越小。竹丛结构呈现丛生竹的立竹量越大,竹丛高度越高。
In order to provide a basis for the selection and cultivation of superior bamboo species for both shoot and timber in Guangxi,8 kinds of container cuttings or stump seedlings of sympodial bamboos were used as research materials to construct experimental forests in Nanning Academy of Forestry,to study the bamboo cluster structure and its correlation after 16 months of afforestation.The results show that:(1)The larger average number of bamboos per plant were Dendrocaiamopsis oldhami(Munro)Keng f.(7.37),D.brandisii(5.75)and B.pervariabilis×B.Grandis 30#(4.00).(2)The larger average DBH of bamboos were Dendrocalamus latiflorus(4.66cm),D.brandisii(4.63cm)and B.pervariabilis×B.Grandis 30#(3.77 cm).(3)The higher of height of the bamboo bush were D.brandisii(7.12 m),Dendrocalamus latiflorus(6.41 m),B.vadidus(6.13m),B.pervariabilis×B.Grandis 30#(6.12 m),Bambusa beecheyana(6.12 m)and Dendrocalamus latiflorus(6.12 m).(4)The number of bamboos,DBH of bamboos and the height of bamboo clumps of D.brandisii are better,so the growth of D.brandisii is the best.(5)Except for the D.aspera,the higher amount of bamboos of the other 7 species of sympodial bamboo,the higher the height of the bamboo cluster.The higher the amount of bamboos of Dendrocaiamopsis oldhami(Munro)Keng f.,the larger the diameter of the bamboo breast.The higher amount bamboos of B.pervariabilis×B.Grandis 30#and B.vadidus,the smaller the diameter of the bamboo breast.The structure of bamboo clump showed that the larger the bamboo stand,the higher the height of bamboo clump.
