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。表4参11Abstract: Rhizome diameter,internode length,and the number of cross rhizomes and jumping rhizomes of a Phyllostachys 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.
