亚美马褂木在闽西地区引种及生长分析

Introduction and Growth of Liriodendron sino-americanum in West of Fujian

摘要: 2005年在福建闽西地区引种亚美马褂木（Liriodendron sino-americanum）17.2 hm2，研究不同坡向（南坡、西北坡、北坡）、不同坡位（下坡位、中坡位、上坡位）和不同施肥措施（施肥、不施肥）对其生长的影响。2015年设立标准地调查。结果表明，造林10 a 后，其平均保存率达86.23%；以南坡向下坡位生长表现最好，平均胸径13.42 cm，平均树高9.44 m，平均单株材积0.067 478 m3；施肥可有效促进亚美马褂木的林分生长，其平均胸径为13.87 cm，平均树高为9.73 m，平均单株材积为0.074 015m3，较不施肥对照处理分别增加了6.77%、7.04%和21.18%。

Abstract: Introduction of Liriodendron sino-americanum was carried out in 2005 in the west of Fujian province with 1-year cuttings. Area of plantation was 17.2ha at different slope aspect and position, with or without fertilization. Sample plots were established in 2015 for investigation. The results showed that mean conservation rate of L. sino-americanum cuttings reached 86.23%, the best growth was at south downhill with the mean DBH of 13.42, mean height of 9.44 and individual plant volume of 0.067478m3. In addition, fertilization could effectively promote the growth of L. sino-americanum with mean DBH of 13.87cm, mean height of 9.73m and individual plant volume of 0.074015m3, 6.77%, 7.04% and 21.18% more than that without fertilization.
