Introduction and growth of Liriodendron sino-americanum in west of Fujian.
Introduction of Liriodendron sino-americanum was carried out in 2005 in the west of Fujian province with 1-year cuttings. Area of plantation was 17.2 ha 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 0.067478 m3. In addition, fertilization could effectively promote the growth of L. sino-americanum with mean DBH of 13.87 cm, mean height of 9.73 m and individual plant volume of 0.074015 m3, 6.77%, 7.04% and 21.18% more than that without fertilization.
