| 摘 要： | 对速生多用途树民占相思进行了不同伐桩高度（25cm,50cm,75cm和100cm)及不直径（4．1－8．0cm和8．1－12．0cm)萌芽更新影响的研究，结果表明，伐桩的萌芽率及平均萌条数随伐桩高度的增加而增加，随直径的增大而减少，萌条直径，长度及直萌条（可望生长成材之萌条）总断面积随伐桩的高低和大小而增减，伐桩最低的萌芽率比以往的结果高4倍以上，以短轮伐期经营的马占相思人工林，采用50－75cm伐桩高度萌芽更新效果好。

| Abstract: | The effect of diameter and height of stumps on sprout regeneration in mangium was studied in a short rotation mangium plantation. The study is based on observations of four height classes (25 cm,50 cm, 75 cm and 100cm) and two diameter classes (4.1~8.0cm and 8.1~12.0cm) of the stumps. The results showed that sprouting percentage of the stumps and number of sprouts per stump increased with the stump height, whereas they decreased with stump diameter. The length and diameter of sprouts and the total basal-area of all upright sprouts per stump increased with the increases in stump height and diameter. For achieving good results of sprout regeneration, it appears that young mangium plantation should be coppiced at heights ranging between 50~75cm. |
