摘要
合江方竹地下茎的生长特性直接影响到发笋质量。研究结果表明合江方竹鞭、根在土壤中主要分布于在0～25cm范围以内，尤以5—10cm分布量最多；鞭角、1／2鞭长处鞭径、鞭节间长度在不同丛间的存在显著或极显著差异；竹鞭具有先行一定长度生长，再在该段的上部集中发鞭的规律性。同时，6～9月温度和降雨是竹鞭长生长的限制因子。
Rhizome growth characteristics of Chimonbambusa hejiangensis affected the quality of shoots instantly. The rhizome growth rules were studied in this paper. The results showed that the rhizome of chimonbambusa hejiangensis was mainly distributed in the depth of 0 -25cm in soil, especially in 5 - 10cm. The rhizome angle, diameter at half of one rhizome and the rhizome length were significantly different between the clones. The more rhizomes grew in a short - term when the underground stems grew to a certain length. Meanwhile it was also found that the temperature and rainfall in June to September were the limiting factors of rhizome growth.
