长条丝竹席和竹材胶合板的原竹利用率分别不超过19.0%和30.4%。生产中竹材资源有效利用率较低的主要原因是竹材秆形结构的影响和加工设备及生产工艺的影响。加工利用原竹时不仅要根据竹材结构规律和加工特点进行,而且还要考虑秆形形态的影响。为减小秆形空间弯曲程度,提高资源有效利用率,就必须增设和改造有关设备及生产工艺。

The effect of management on growing and form of culms of moso bamboo (Phyllostachys pubescens) with the similar density about 1 950~2 200 culms per ha for producing culms was studied at the central distribution region of moso bamboo in China, and the results showed the culms growing and form vary obviously among the stands under different management methods. In general, the culms of moso bamboo managed for producing culms managed intensively grow better than that managed normally, and that without any management...

The effect of management on growing and form of culms of moso bamboo (Phyllostachys pubescens) with the similar density about 1 950~2 200 culms per ha for producing culms was studied at the central distribution region of moso bamboo in China, and the results showed the culms growing and form vary obviously among the stands under different management methods. In general, the culms of moso bamboo managed for producing culms managed intensively grow better than that managed normally, and that without any management the worst. Compared with that managed normally or without management, the culms form of moso bamboo managed intensively are the best, and it is higher by 5% in average than that managed normally, 12% higher than that without any measures. The culms weight of moso bamboo managed intensively can reach 31.37 kg, but that managed normally 28.46 kg and 23.33 kg without any measures. The basic relationships are similar between the total height and DBH of the culms managed at different degrees. The relationships between the main form indexes of moso bamboo culms managed at different degrees have been modeled.

在毛竹中心分布区福建省邵武市和江西省宜丰县调查研究了人工经营干扰对材用毛竹秆形生长和变异的影响。结果表明 :不同经营强度下毛竹的秆形结构变异差异显著。立竹密度基本相似的纯林中 ,材用毛竹秆形生长表现为 :集约经营优于一般经营 ,一般经营优于粗放经营。在中心分布区 ,不论立地条件是否相同 ,多年采取集约经营的毛竹的竹秆不仅尖削度小 ,枝下高长 ,壁厚 ,而且全杆高度比一般经营的平均约高出 5% ,比处于粗放经营的高出达 12 % ;采取集约经营的毛竹的平均秆鲜质量可达 31.37kg,而一般和粗放经营状态下分别仅为 2 8.4 6kg和 2 3.33kg。不同经营强度下毛竹秆高随胸径的基本变化规律相似 ,但是集约经营的毛竹全秆高随胸径稳定增长 ,而经营水平低的变化幅度大。即使毛竹的胸径相同 ,处于集约经营状态下毛竹秆高、秆鲜质量均比一般经营和粗放经营的明显大。多年采取 3种不同强度经营的毛竹主要秆形标识值之间关系可用不同的数学模型描述

Current research on bamboo culm form is summarized in this paper, especially in the relationships among the different indexes of bamboo culm form.According to the situation in this research field and other subjects, the problems and the p rospect about research on bamboo culm form are discussed.

综述了迄今为止国内外竹子秆形生长和变异规律的研究进展。在不同地区针对一些竹子的秆形结构进行了调查研究 ,并得出一些竹子的主要测树因子之间的变化关系的经验方程。其中 ,有关毛竹的秆形生长变异进行的研究最多 ,其它一些地区性主要经济中小径竹的也有一定研究。所得的经验方程不同竹种间有一定差异即使同种竹子如毛竹也不统一。结合树木及森林生长和干扰、收获预估模型的发展趋势对竹子的秆形生长和竹林收获预估的研究前景进行了分析。
