摘要
通过对撑麻7号竹材构件因子的调查分析,结果表明:立竹地径与全高、相同年龄立竹秆壁厚呈显著的正相关,而同一径级、不同年龄立竹的竹秆壁厚存在差异;竹秆相对高度竹壁厚度与秆径呈一致性变化趋势,立竹径级与竹秆相对壁厚无相关,平均相对壁厚0.146;竹秆平均节间长与立竹地径无显著的相关性,平均节间长26.75cm;构建了立竹地径与材积的数学模型V=0.01226-0.005948D+0.00116D2-0.000051D3。
Research on component factors of Bambusa pervariabilis × Dendrocalamus latiflorus indicated that： Bamboo basal diameter had positive correlation with full height and the culm cliff thickness of bamboo culm with the same age, and there was significant difference between the culm wall thickness with the same diameter but different age. The dynamic change of culm wall thickness at relative height was consistent with culm diameter, but culm diameter had no correlation with relative culm wall thickness and the average relative wall thickness was 0.146; the average internodes length had no significant correlation with bamboo basal diameter. Eventually, the matrix of timber volume and bamboo basal diameter was established as ： V = 0.01 226- 0.005 948 D ＋ 0.00 116 D^2- 0.000 051 D^3.
