【摘要】 选择16种江西常绿阔叶林的主要建群树种或优势树种,进行人工造林试验,以了解其在人工造林条件下的生长状况。观测造林成活率以及胸径、树高、冠幅生长指标,通过方差分析、多重比较、系统聚类,评价试验树种人工幼林生长表现,并运用回归分析方法研究树高生长规律。结果表明:黎蒴栲表现最优,半枫荷、秃瓣杜英、鹿角栲、栲树、香港四照花、青冈、银木荷、观光木、木荷造林效果较好,其它树种较差。更多还原

【Abstract】 16 main constructive species or dominant species of evergreen broadleaf forests in Jiangxi,were selected for afforestation test to understand the growth status under plantation conditions.The survival rate of afforestation and DBH,tree height,crown growth indicators were observed.By analysis of variance,multiple comparisons,hierarchical cluster,the growth status of the young plantations was evaluated. The growth patterns of tree height were analyzed by using regression analysis. The results showed that the performance of Castanopsis fissa was the best,that of Semiliquidambar cathayensis,Elaeocarpus glabripetalus,Castanopsis lamontii,Castanopsis fargesii,Dendrobenthamia hongkongensis,Cyclobalanopsis glauca,Schima argentea,Tsoongiodendron odorum and Schima superba was comparatively good,that of opther species was not as good.更多还原
