毛竹竹冠由秆、枝、叶三部分组成。竹秆分枝部分是竹冠的支柱,竹秆上每一个分枝的节和枝、叶合称为一个枝盘。每一枝上着生主枝、侧枝、小枝,各种枝条按一定规律分布在竹秆四周,构成竹冠的空间支架。每一个叶枝上着生3—5片竹叶,均匀分布在竹冠上形成绿色的叶层,有效地利用太阳光能进行光合作用,生产有机物质。竹冠结构是指竹冠中秆、各种枝条、竹叶的数量及其在各盘枝上的分布。关于毛竹的秆形结构,作者曾作过报道,本文主要论述毛竹竹冠结构的规律性。1979年以来,我们在江苏宜兴县林场,共调查70株标准竹,每株标准竹伐倒后,记录竹龄、胸径、高度、枝下高、总节数、枝下节数、竹冠节数(枝盘数)、竹秆重量以及枝、叶重量等,并按枝盘号调查主枝、侧枝、小枝、叶枝、叶片数等。
Bamboo bamboo crown by the stalk, branches, leaves three parts. Part of the bamboo stalk is the bamboo crown pillars, bamboo branches on each branch and branches, leaves collectively known as a stick. Each branch on the main branch, collateral, twigs, all kinds of branches according to certain rules around the bamboo stalks, bamboo scaffolding constitute a space. Each branch has 3-5 green bamboo leaves, evenly distributed in the bamboo crown to form a green leaf layer, the effective use of solar energy for photosynthesis, the production of organic matter. Bamboo crown structure refers to the bamboo crown in the stalks, all kinds of branches, the number of bamboo leaves and its distribution on each plate. On the bamboo stalk structure, the author has made reports, this paper mainly discusses the regularity of bamboo bamboo crown structure. Since 1979, we surveyed 70 standard bamboo plants in Yixian County, Jiangsu Province. After each standard bamboo was cut down, the bamboo age, DBH, height, branch height, total number of nodes, number of bamboo crown segments (Number of branches), the weight of bamboo stalks, the weight of branches and leaves, and the number of branches, branches, branchlets, leaf branches and leaves according to the branch number.
