[Method] The growth situation of L. chinense seedlings and soil fertility in northern Guangxi Province were investigated. [Result] The L. chinense seedlings in northern Guangxi Province showed significant changes during the growth period. Among the three- year-old L. chinense plants, the average plant height reached as high as 331.11 cm, the average ground diameter was 5.05 cm, and the average crown diameter was 122.22 cm. After three years＇ afforestation with one-year-old seedlings, the av- erage plant height of L. chinense was 357.20 cm, the average ground diameter was 6.53 cm, and the average crown diameter was 170.43 cm. The detection results of soil fertility were as follows： the soil was strongly acidic; the organic matter and to- tal phosphorus contents were moderate; and the total potassium content was rela- tively abundant. [Conclusion] L. chinense grows rapidly in northern Guangxi Province of China, and is suitable for extension in this area.展开更多
