本文通过对一般经营材用毛竹林30个鞭系的剖析,探讨了毛竹鞭系个体结构。1)材用毛竹林鞭系大小不一,平均鞭长53.3-100.7米,立竹3.3-8.6株;2)主要由20-40厘米土层中的壮鞭中段侧芽萌笋成竹,鞭段先端侧芽抽发新鞭;3)鞭系具有多龄级和多层次结构;4)鞭系中侧芽有效率仅4.1%。据此笔者认为,在竹林培育中应进行按年龄择伐、清除老鞭、提高侧芽有效率等措施。
In this paper, we analyze the whip whorls of 30 whorls of bamboo in general management timber and discuss the individual structure of Phyllostachys pubescens. 1) Material Bamboo whip whip size, the average whip length 53.3-100.7 m, standing bamboo 3.3-8.6 strains; 2) mainly by the 20-40 cm layer in the middle of sprouting midrib sprout bamboo shoots, whip Apex sprouting new whip; 3) whip system with multi-age class and multi-level structure; 4) whip side of the lateral bud efficiency of only 4.1%. Therefore, I believe that in the cultivation of bamboo should be carried out by age-selective cutting, removal of the old whip, improve the efficiency of lateral buds and other measures.
