摘要：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
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.
