摘　　要：[目的]了解雷公山自然保护区冷竹的生物特性。[方法]采用问卷调查和样地调查相结合的方法研究雷公山自然保护区冷竹出笋时间至成竹时间段的生物特性。[结果]出笋时间为4月上旬,结束时间为5月中旬,6月上旬开始展叶,7月底成竹;冷竹笋死亡率为58.8%,成竹率为41.2%;适当对竹笋进行采集可促进竹笋的新生;4月中旬至下旬为竹笋盛产期,5月上旬产笋量逐渐下降;雷公山自然保护区年平均冷竹笋产量达0.373 kg/m^2,全年总生长量为2 113.70 t。[结论]试验结果为合理采笋和保护野生资源提供了参考。[Objective] The aim was to study the biological characteristics of Leigongshan national nature reserve. [Method] By using questionnaire investigation and sampling plots investigation method,the biological characteristics of Lengzhu in Leigongshan national nature reserve from shooting to mature period were studied. [Result] Shooting was from early Apr. to mid-May,leaf unfolded in early Jun.,matured in late Jul.; the mortality was 58. 8%,mature rate was 41. 2%; appropriate collection of bamboo shoots could promote the rebirth; from mid-Apr. to late was bamboo shoots rich period,the yield in early May decreased gradually; the annual average yield was 0. 373 kg/m^2,total increment in whole year was 2 113. 70 t. [Conclusion]The experiment results provide reference for rational harvesting of bamboo shoots and protecting wild resources.
