摘　　要：对2 a生麻栗坡含笑幼林进行不同抚育技术措施处理试验。结果表明,清除杂灌和松土处理对麻栗坡含笑生长的效果最好,其幼林树高、胸径、地径等生长指标分别比对照增长20.5%、58.2%和41.1%。割除杂灌处理效果次之,树高、胸径、地径等生长指标分别增长4.5%、16.6%和17.4%。合理的抚育技术措施处理对促进林木生长和加速幼林郁闭具有重要作用。Growth effects of two year old young forest stand of Michelia chartace under different tending measures were studied. The results showed that treatments of scavenging weeds and shrubs, and loosening soil had the best growth effect. The average height, DBH and ground diameter of young forest stand increased by 20.5% , 58.2% , 41.1% respectively compared with the control. The effect of scavenging weeds and shrubs took second place, the average height, DBH and ground diameter of young forest stand increased by 4.5% , 16.6% and 17.4% respectively. Reasonable scientific tending measures have an important effect on promoting the growth of trees and accelerating the crown closure of young trees.
