摘要
采用设置样地的方法对贵州省引种的柚木进行生长情况的调查分析.结果表明,贵州省引种柚木的适生区域是南部的南、北盘江低热河谷地区,红水河、南盘江岸边海拔700 m以下以及北盘江两岸海拔550 m以下地区.在适生区域发展柚木采用四旁植树的方法效果最佳,坡地造林宜选择土层厚度80 cm以上的地域,采取反斜坡带状整地效果较好.
By using setting sampling plot method,the growth status of introduced Tectona grandis has been analyzed in Guizhou Province.Results showed that the suitable area for introduced Tectona grandis in Guizhou Province are in south of Nanpan River low and hot Valley,Red River,Nanpan river shore of altitude below 700m and Beipan Riverbanks of altitude below 550m.The best way to develop Tectona grandis in sustainable area is using all around tree planting method,afforestation on slope should choose area of soil thickness above 80cm,and anti-slope strip site preparation could make better effects.
