摘要
[目的]在桂北地区进行中国马褂木的苗木培育和造林研究,为中国马褂木在该地区的推广种植提供理论依据。[方法]对桂北地区中国马褂木的苗木生长情况及土壤肥力进行分析测定。[结果]在桂北地区培育的中国马褂木苗木生长变化显著,3 a中国马褂木实生苗平均株高可达331.11 cm,平均地径为5.05 cm,平均冠幅为122.22 cm;用1年生苗木造林3 a后,中国马褂木平均株高可达357.20 cm,平均地径为6.53 cm,平均冠幅为170.43 cm。造林地土壤肥力检测状况为:土壤为强酸性,有机质微缺,全磷含量中等,全氮含量丰富,全钾含量较丰富。[结论]中国马褂木在桂北地区生长迅速,适宜在该地区推广种植。
[ Objective ] To carry out seedling cultivation of Liriodendron chinense （Hemsl） Sarg. in northern Guangxi Province of China, and to provide theoretical basis for the extension of L. chinense in this region. [ Method] Growth situation and soil fertility of L. chinense seedlings in northern Guangxi Province were analyzed and researched. [ Result] L. chinense seedlings showed significant changes during the growth period in northern Guangxi Province of China. The average plant height of three-year L. ehinense reached as high as 331.11 cm; the ground diam- eter was 5.05 cm and crown diameter was 170.43 era. After three years＇ afforestation by one-year-old seedlings, the average plant height of L. chinense was 357.20 cm; the ground diameter was 6.53 cm and crown diameter was 170.43 cm. Detection results of soil fertility was as follows： soil had strong acidity, organic matter and total phosphorus had middle content; total potassium content was relatively abundant. [ Conclusion] L. chinense grows rapidly in northern Guangxi Province of China and is suitable for extension in this area.
