文章结合广东梧桐山国家森林公园林地条件，观察金线莲（Anoectochilus roxburghii）幼苗在林下的生长表现，统计生长 30 和 180 d 的植株成活率、保存率、苗高和生物量的增长量。结果表明，金线莲在林下生长良好；生长 30 d，植株成活率为 82.5%~95.0%，植株平均苗高为 10.3~12.3 cm，苗高净生长量为 0.72 cm；生长 180 d，保存率在 37.5%~95.0% 之间；植株平均苗高为 13.2~19.2 cm，平均生物量为 3.17~3.83 g，其苗高和生物量净生长量分别为 7.46 cm 和1.87 g。

Abstract: |
|
In this paper, the growth status of Anoectochilus roxburghii seedlings under forest was observed, and the plant survival rate, seedling height and biomass growth were analyzed after 30 and 180 days of growth in Wutongshan National Forestry Park. The results showed that A. roxburghii seedling grew well in the forest. After 30 days of growth, the survive rate of plantlets was 82.5%~95.0%, the average plant height was 10.3~12.3 cm, and the net growth of height was 0.72 cm. After 180 days of growth, the survival rate was 37.5%~95.0%. The average plant height was 13.2~19.2 cm and the average biomass was 3.17~3.83 g. The net growth of height and biomass were 7.46 cm and 1.87 g.
