【摘要】 调查了浙江南部大木竹的秆形状况,包括秆高、鲜秆质量、尖削度、竹壁厚和节间长等一系列指标。以毛竹为参比竹种,对数据进行统计分析并拟合曲线,结果发现:相同胸径下,大木竹的全高大于毛竹;尖削度较毛竹略小;壁厚随竹秆高度增大而减小的速率比毛竹快;拟合大木竹鲜秆质量-胸径的幂函数方程为:M=0．232 7(DBH)2.189 9, 与毛竹相比,同样胸径的大木竹鲜秆质量比毛竹大;大木竹的节间长度随高度的变化趋势呈二次曲线,在胸径为4 -11 cm范围内,节位数10-15处的节间长度最大,可达50-65 cm。更多还原

【Abstract】 The structure of culm form of Bambusa wenchouensis was studied, including culm height, culm weight, culm taper, wall thickness and internodal length etc. Compared with moso bamboo, the research results showed that if their breast diameters (D) were equal, B. wenchouensis had a higher stem, weightier culm, a little smaller taper and thicker wall, although its wall thickness decreased more quickly than moso bamboo as culm height increases. The best structural model of fresh culm weight (M) was M = 0. 232 7 (DBH)2.189 9, and the relation between its internodal length and culm height could be distributed with conic. When the breast diameter ranges from 4 to 11 cm, internodal length could reach the maximum of 50-65 cm as the node was 10 - 15.更多还原
