摘要
为探索毛竹鞭笋高产经营技术,于竹鞭生长期(5—9月)观测研究了毛竹笋竹两用林地下竹鞭动态生长规律。结果显示:鞭梢延伸生长的日均生长量随时间的推进呈现"慢—快—慢"的规律,其中7月份的日均生长量最大;鞭梢日均生长量在各月份间存在极显著差异;鞭梢直径生长与鞭梢延伸生长进程基本一致,即7月份的鞭梢直径最大。研究结果表明,鞭笋大年(春笋小年)的7月份是鞭笋采集的最佳季节。
In order to explore the high-yielding management techniques for Phyllostachys pubescens rhizome and shoots,the dynamic growth rules of rhizome in Ph. pubescens forest for shoot and timber were observed in rhizome growth period（ May-Sept.）. The results showed that the average daily growth of rhizome width presented the＂slow-fast-slow ＂rule over time,and the daily growth was the fastest in July. Rhizome average daily growth varied significantly among different months. The diameter growth and width growth of rhizome were kept consistent in their process,i. e.,July is the month to see the largest rhizome diameter. The results indicated that July is the best season to pick rhizomes and shoots.
