福建南靖引种5个观赏竹种的生长特性

文章对比分析了引自福建华安县的泰竹（Thyrsostachys siamensis）、黄金间碧竹（Bambusa vulgaris ‘Vittata’）、撑麻青1号Bambusa pervariabilis×（Dendrocalamus latiflorus +Bambusa textilis）]、青丝黄竹（Bambusa eutuldoides）和花吊丝竹（Dendrocalamus minor var.amoenus）5个竹种在福建南靖县的生长表现。结果表明：5个竹种均表现出良好的生长适应性；5个竹种间在竹高、胸径、出笋量及丛幅指标上均存在显著差异（P<0.05），在立竹度指标上差异不显著（P>0.05），其中黄金间碧竹的胸径最大，撑麻青1号的出笋量和丛幅最大，花吊丝竹立竹度最多。黄金间碧竹和撑麻青1号的叶、枝和秆生物量和含水率均较高，表明他们具有较强的光合产物积累能力，有利于新竹生长和形态建成。

Growth Property of 5 Ornamental Bamboo Species Introduced in Nanjing City,Fujian Province

The growth properties of 5 ornamental bamboo species which are introduced from Hua'an county of Fujian province, i.e., Thyrsostachys siamensis, Bambusa vulgaris ‘Vittata’, B. pervariabilis×(Dendrocalamus latiflorus + Bambusa textilis), B. eutuldoides var. viridi-vittata and Dendrocalamus minor var. amoenus, are compared and analyzed in Nanjing county, Fujian province. The results show that all the 5 bamboo species show good growth adaptability; they are significantly different in the height, DBH, shoot yield and clump size (P<0.05), but show the least significant difference in the quantities of living culms (P>0.05). Among which, B. vulgaris ‘Vittata’ has the largest DBH, B. pervariabilis×(D. latiflorus+ B. textilis) has the highest shoot quantities and clump size, and D. minor var. amoenus has the largest quantities of living culms. B. vulgaris ‘Vittata’ and B. pervariabilis×(D. latiflorus+ B. textilis) have the highest biomass and moisture content in leaves, branches and culms, and show a stronger accumulation ability of photosynthetic product, which is conducive to the growth and morphological formation of new bamboos.
