金花茶回归试种

金花茶Camellia nitidissima是世界性珍贵稀有植物,因过度采伐致其野生资源急剧减少,野外种群逐渐消失。开展金花茶物种回归试验,对恢复金花茶种群有重要意义。为此,在广西防城金花茶国家级自然保护区实验区内选取适宜的金花茶回归地,建设样地,基于样方调查及生态环境调查等方法,研究金花茶回归自然后的效果。结果表明,两个样地的金花茶回归实生苗成活率为94.57%,部分苗木因阳光照射时间长叶片偏黄,回归移植时需林下遮荫。

Preliminary Study on Re-introduction of Camellia nitidissima

Camellia nitidissima is a precious and rare species. Its distribution area is gradually reducing because of human activities. The research on C. nitidissima re-introduction has important and directional significance for the population restoration of Camellia species. In this study, selection of the site of re-introduction, construction of sample plots and investigation of ecological environment were carried out to explore re-introduction techniques of C. nitidissima, and afford to the reference for re-introduction and population restoration of Camellia species.
