摘　　要： 研究了11种华南乡土阔叶树种幼树在广东增城市林科所松杉人工林林下的生长表现,结果表明:4种壳斗科植物黎蒴、米锥、甜锥和槟榔青冈在移植后5 a均具有较高的树高和冠幅生长量,可作为人工林改造优良树种;香椿在前期生长表现良好,而移植后4~5 a生长速度有所下降,反映该树种随着年龄增长,其需光性加强,该树种仅适用于低密度人工林的改造;石笔木生长虽然稍慢,但其耐荫性较强,在林下生长良好,可作为次生林改造树种;樟树、枫香和火力楠等树种在林下生长不良。样方调查结果表明:松杉林下植物以耐荫性和鸟播植物为主。 The growth of 11 native broad-leaved tree species in a coniferous plantation located in Zengcheng,Guangdong Province was studied.The result showed that the saplings of four Fagaceae species(Castanopsis fissa,C.carlesii,C.eyrei,and Cyclobalanopsis bella) had vigorous growth in the plantation during the first 5 years,which were excellent species in the ecological plantations.The saplings of Toona sinensis had rapid growth in the first 3 years,but the growth declined in the fourth and fifth year.It had higher ...
