[目的]探讨华中神农箭竹更新幼龄地下茎的伸长规律。[方法]在神农架国家自然保护区内凉风垭设置样地，选取六丛独立生长的神农箭竹作为研究样本，测量各龄级地下茎长度与直径，地下茎龄级采用倒逐龄法确定。[结果]通过样地调查研究，可以发现在神农箭竹的幼苗期，地下茎随时间序列快速延长，呈指数曲线增长。研究结果表明，克隆更新的神农箭竹幼苗虽然无性繁殖生长了15年，但是此新世代的种群还未达到稳定状态。[结论]该研究通过对神农箭竹地下茎伸长规律的探索，以期为掌握此物种生长周期的基本特性提供理论支持。

[Objective] The aim was to investigate the rhizome elongation growth of umbrella bamboo （Fargesia murielae） seedlings in China. [Method] The study was conducted in Liangfengya, Shennongjia National Nature Reserve. In the field investigation, six clumps of umbrella bamboo which grow independently were randomly selected and labeled. Rhizome elongation growth parameters, length and diameter of all the ages were measured. The age classes of bamboo rhizome were ascertained by age grade backtracking method. [Result] Field investigation suggested that at seedling phase, rhizome of umbrella bamboo prolonged very quickly under yearly time sequence, following an exponential curve. It indicated that although it was 15 years since the mother population died back, new generation had not been established its stable population yet. [Conclusion] Studying elongation regulation of umbrella bamboo may provide the theory understanding of life cycle of this long lived bamboo species.
