桉树萌芽林补植造林技术措施探讨及效果分析

Exploration and Effect Analysis of the Technical Measures for Supplementary Plantation and Afforestation of Eucalyptus Sprout Forest

摘要: 于2020年6月在广西壮族自治区国有东门林场在桉树采伐迹地上进行补植造林试验，结果显示，林木的平均树高、平均胸径逐年增加，林木健康；2.5 a生林分，补植林分平均胸径是对照林分的102.8%，平均树高是对照林分的102.0%，单位面积蓄积量是对照林分的107.2%，在桉树有效萌芽桩低于初植密度50%的采伐迹地内补植造林是成功的。

Abstract: In June 2020, a replanting experiment was carried out in the state-owned Dongmen Forest Farm of Guangxi Zhuang Autonomous Region on the cut land of Eucalyptus. The results showed that the average tree height and average DBH of the trees increased year by year, and the trees were healthy. The average DBH and average tree height of the replanted stand were 102.8% of that of the control stand, 102.0% of that of the control stand, and the stock volume per unit area was 107.2% of that of the control stand. Replanting was successful in the cut land where the effective sprouting pile of Eucalyptus was lower than 50% of the initial planting density.
