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.
Abstract
[Objective] To carry out seedling cuhivation 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.chinense reached as high as 331.11 cm;the ground diameter was 5.05 cm and crown diameter was 170.43 cm.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.
