摘　　要：研究挖掘鞭笋8 a后的毛竹Phyllostachys pubescens笋材两用林基地中竹鞭的鞭径、节间长、岔鞭数量和跳鞭等情况,旨在为鞭笋生产提供科学依据。结果显示:①岔鞭鞭径比主鞭鞭径减少0.10 cm。②挖鞭笋比不挖鞭笋试验之间的竹鞭整体鞭径平均增加0.30 cm。③不同母竹年龄(1,2,3度)的主鞭鞭径大小,挖掘鞭笋的比不挖鞭笋的增加了0.30～0.70 cm。④挖鞭笋比不挖鞭笋之间的平均竹鞭节间长度增加0.31 cm。⑤岔鞭的条数平均增加2条。t=6.006>t0.01=3.355,存在极显著差异。⑥挖鞭笋后的样地中没有找到跳鞭。Rhizome diameter, intemode length, and the number of cross rhizomes and jumping rhizomes of a PhyUostachys pubescens forest which was used for both bamboo shoots and bamboo poles and whose rhizome shoots were dug out and removed for 8 years were studied. Results showed that compared with the rhizome shoot forests that were not removed： （1） cross rhizome diameters decreased 0.1 cm than main rhizome diameters; （2） the average diameter of the all rhizomes increased 0.30 cm; （3） the average diameter of the main rhizomes increased 0.30 - 0.70 cm; （4） the average internode length of the all rhizomes increased 0.31 cm; （5） the cross rhizome number significantly increased two（t = 6.006〉t0.01 = 3.355）; and （6） in rhizome shoot forests that were removed, there were no jumping rhizomes.
