摘要
大叶芳樟由于自身发育特点,只有无性繁殖才能保持母树的优良特性。本文从春、夏、秋、冬四季对大叶芳樟大田扦插成活率作调查,找出其最适宜的扦插季节。结果表明大叶芳樟在夏季生根时间和新梢生长时间最短,秋季成活率最高,可达75%,冬季的成活率最差。
Because of its own growth characteristics, only asexual reproduction of Cinnamomum porrectum can maintain the excellent characteristics of mother-trees. The four survival rate of C. porrectum with field cutting at spring, summer, autumn,winter was investigated, the most suitable cutting season was found out. The results showed that rooting time and the growth time of new shoots of C. porrectum in the summer was the shortest; the survival rate is the highest in autumn, up to 75%, and the worst in winter.
