摘　　要：对5个杉木优良品种1年生苗木的苗高、地径、高径比进行调查分析,结果表明:参试的杉木优良品种苗木生长良好,苗木的苗高、地径、高径比在品种间差异达极显著水平。其中,沙县官庄杉木第2.5代种子园种子培育的苗木1年生时生长表现最优,其苗木高,地径粗,苗木健壮;邵武卫闽杉木第2.5代、第2代苗木和沙县官庄杉木第2代苗木生长表现一般;三明市郊杉木第2代苗木生长表现最差。This paper studied the growth differences among 5 superior varieties of Cunninghamia lanceolata at seedling stage.The results based on the analysis of seedling height,ground diameter,seedling height/diameter showed that the seedling grew at a sound condition,and the differences among seedling height,ground diameter,and seedling height/diameter of different varieties reached extremely significant.Seeds from the second point five generation seed orchard in Guanzhuang were the best variety at seedling stage.
