摘　　要：在30年生马尾松林下进行了不同阔叶树种套种试验.结果表明:在马尾松林冠下套种不同阔叶树种生长存在明显差异,其蓄积大小排序为拉氏栲>格氏栲>青栲>苦槠,其中20年生拉氏栲的年平均蓄积生长量分别是格氏栲、青栲和苦槠的1.06、1.26和1.49倍;拉氏栲和格氏栲是马尾松林冠下套种的首选树种,生长中等的树种有青栲,苦槠生长较差,不适宜作为马尾松林冠下造林树种;利用马尾松林分具有林冠稀疏和透光度大的特点,在马尾松林冠下套种拉氏栲、格氏栲不仅能充分利用林分地上和地下的空间,而且对于减轻马尾松林松毛虫危害具有重要现实意义,是值得南方林区大力推广的林冠下套种模式.The growth of different broad-leafed tree species under the crown of 30-year-old Pinus massioaiana plantation was investigated. The result shows that there were significant differences on the growth of different broad-leafed stands under the crown of this plantation. The stand volume of different tree species was in the sequence：Castanopsis kawahamii〉Castanopsis lamontii〉 Cyclobalanopsis myrsinaefolia〉Castanopsis sclerophylla. The annual volume growth of 20-year-old Castanopsis lamontii plantation was 1.26 times as much as that of Cyclobalanopsis myrsinaefolia plantation, 1. 49 times that of Castanopsis sclerophylla. Castanopsis hawakamii and Castanopsis lamontii were the practicable tree species for planting under the crown of Pinus massioniana plantation.
