摘要:
对新兴、丰顺、英德3 个地方的连片麻竹Dendrocalamus latiflorus 林分生长性状和竹材性状进行系统调查及分析比较,结果表明:新兴麻竹林分竹丛内竹秆数量多且竹秆年龄结构较为均衡,丰顺麻竹林分竹丛内竹秆数量很少且竹秆年龄结构不均衡,英德麻竹林分竹丛内竹秆数量少,竹秆年龄结构亦不均衡;160 m2 竹林中,新兴麻竹林分竹秆数量显著多于英德和丰顺,达263 株。一年生竹秆平均胸径以丰顺最大,其他两地较小;其他年龄竹秆平均胸径新兴、英德较大,丰顺最小;新兴、英德两地间麻竹林分竹秆胸径大小在所有年龄级中均无显著差异。3 个地区间麻竹竹秆的加工性状有显著差异,新兴麻竹竹秆分枝特别高、秆重大,英德麻竹秆高最大,分枝较高,因而两者均是较好的加工重组竹材的材料;丰顺麻竹材分枝特别低,但秆重较大,作为重组竹材的加工材料还是可行的。3 个地区的麻竹竹秆基本密度大致相同。

Abstract:
The growth characteristics and recombing characters for Dendrocalamus latiflorus forests and bamboo were systematically analyzed and compared in Xinxing, Fengshun and Yingde. The results showed that the number of bamboo stalks of D. latiflorus forest was large and the age structure of bamboo stalks was relatively balanced in Xinxing, which was the opposite in Fengshun and Yingde. Among 160 m2 D. latiflorus forests, the number of bamboo stalks in Xinxing was significantly more than that in Yingde and Fengshun, reaching 263 plants. The average diameter at breast height of annual bamboo stalks was the largest in Fengshun and smaller in the other two places. The average DBH of other age bamboo stalks in Xinxing and Yingde was bigger and the smallest in Fengshun. There was no difference in DBH of bamboo stalks between Xinxing and Yingde in all age stage. There were signifcanltly difference for Bamboo recombing characters in three regions. The branch of D. latiflorus from Xinxing was particularly high,and the weight of its culm was biggest. The height of the culm of D. latiflorus from Yingde was biggest and its branches were higher. The bamboo recombing characters of D.
