国家植物园(北园)6种箬竹属竹鞭生长调查

Investigation on Rhizome Growth of Six Indocalamus Species in China National Botanical Garden(North Garden)

对国家植物园引种的6种箬竹属植物的竹鞭生长情况进行实地调查,并开展了竹鞭繁殖试验。结果表明:阔叶箬竹和美丽箬竹生长势处于上升阶段,箬叶竹、箬竹和髯毛箬竹生长势处于下降阶段,善变箬竹生长势处于衰弱阶段。对于生长处于下降阶段或衰弱阶段的竹种,需要尽早进行人工干预,加强抚育管理。研究结果可为北京地区箬竹属植物的栽培管理及科学应用提供参考。

The rhizome growth of six Indocalamus species introduced into National Botanical Garden(North Garden)is investigated,and bamboo rhizome propagation experiments are conducted.The results show that the growth vigor of I.latifolius and I.decorus stays in the rising stage,I.tessellatus,I.longiauritus,and I.barbatus are in the declining stage of growth vigor,and I.varius sp.is in a stage of weak growth vigor.For bamboo species whose growth vigor is in a declining or weak stage,early intervention is required to strengthen tending management.The research results can provide references for the cultivation,management and application of Indocalamus species in Beijing.
