摘要
对天目山自然保护区内的毛竹竹鞭进行了为期1年的动态生长跟踪试验研究。结果表明,毛竹竹鞭的年生长量进程表现出"慢-快-慢"的节律,鞭梢直径的生长进程与之基本一致;7～9月为竹鞭速生期,也是其最佳生长时期。水平方向上,竹鞭的延伸方向以"向前"为主,极少发生转弯现象;垂直方向上,竹鞭的延伸方向以"向下"为主,"平行"生长也较多发生。毛竹属典型的浅根竹种,竹鞭分布范围为0～50 cm土层,主要分布在0～20 cm土层。
The 1-year experimental research on dynamic growth tracing was performed on Phyllostachys pubescens rhizomes in Tianmushan nature reserve.The results showed that the yearly yield process of P.pubescens rhizomes showed ＂slow-fast-slow＂ regularity and diameter growth process of rhizome end was basically consistent with this;the period from Jul.to Sep.was fast growth period of P.pubescens rhizomes,also their best growth period.In horizontal direction,the bamboo rhizomes extended forward mainly and rarely turned;in vertical direction,the bamboo rhizomes extended downward mainly and the parallel growth also occurred more.P.pubescens belongs to typical superficial-root bamboo species,the distribution range of bamboo rhizome was 0-50 cm soil layer,mainly distributed in 0-20 cm soil layer.
