对速生多用途树种马占相思进行了不同伐桩高度(25cm、50cm、75cm和100cm)及不同直径(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、长度及直立萌条(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报道的结果高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。
The effects of spruce height (25cm, 50cm, 75cm and 100cm) and sprouting renewal of different diameters (4.1 ~ 8.0cm and 8.1 ~ 12.0cm) were studied on Acacia mangium, a species of fast growing multipurpose tree species. The rate and the average number of sprouts increased with the height of cutting pile increased, but decreased with the increase of diameter. Sprout diameter, length and erect sprout (expected to grow into the material of the sprout) the total cross-sectional area with the height and size of the cut pile increases and decreases. The lowest rate of stumping was 4 times higher than previously reported. Acacia mangium plantation with short rotation period, using spruce height of 50 ~ 75cm regeneration effect is good.
