| 摘 要： | 对开花刺竹子林分生长和天然更新状况调查结果表明：（1）刺竹子4月上旬开花，6月初结实，花呈纺锤形，浅黄色；（2）结实刺竹子每公顷的立竹度为4．1-8．3万株；胸径0．49-0．83cm；竿高70—519cm；不同立地条件下，刺竹子生长状况不同；（3）随着种子在枝上的逐渐成熟，刺竹子的地上部分开始死亡；（4）刺竹子鞭节长1．21-3．86cm，直径0．34-0．81cm，活鞭呈淡黄色或白色，死鞭呈黑褐色；（5）空旷地的刺竹子天然更新能力明显强于林冠下的刺竹子。 |

The results showed that Ch.pachystachys blossoms in early April and bears seed in early June. The yellow flowers look like spindles. There are 41 000-83 000 Ch.pachystachys per hectare, whose DBH and height are in the range of 0.49-0.83 cm and 70-519 cm, respectively. The growth and seed bearing of natural Ch.pachystachys are different in different site conditions. Aboveground part of natural Ch... |
