毛竹(Phyuostachys Pubescens)地下鞭根系统(注1)有别于一般树木根系,不仅是肥、水吸收的主要器官,而且还是毛竹无性繁殖、扩展、更新的物质基础。因此,地下鞭根系统生长发育的好坏和生理活动性能的强弱都直接影响地上部分的成竹生长。因此,对毛竹鞭根活力进行了测定,现将测定结果简述如下; Phyostachys pubescens underground rhizome system (Note 1) is different from the general tree roots, not only is the main organs of fertilizer and water absorption, but also asexual reproduction, expansion, renewal of the material base. Therefore, the growth and development of the underground whip root system and the physiological activity of the performance of the direct impact on the aboveground growth. Therefore, the root activity of bamboo rhizome was measured, the measurement results are summarized as follows;
