摘　　要：本文通过对旌德县蔡家桥林场9-23年生7种不同混交檫木林分样地调查和分析,结果表明林龄相同、不同混交比例的檫木林分,檫木平均高生长无明显差异;但进入中龄林以后,檫木平均胸径、单株材积生长差异较大,其中4檫6杉混交方式的檫木生长要明显高于其他林分。In this paper a survey analysis was made on the 9-23-year-old Sassafras tsumu stands with 7 mixed patterns on Caijiaqiao Forest Farm in Jingde County. The results showed that there were no significant differences in the height growth among the same-year-old stands with different mixed proportions. But there were significant differences in the mean DBH growth and single volume growth when the plantations reached middle ages thereafter, of which the growth of Sassafras tsumu in the mixed stands with 4 Sassafras tsumu and 6 Cunninghamia Lanceolata was significantly higher
