摘　　要：为对比杉木优良品种区域造林的效果,选用本地普通苗(对照组)、西山良种苗和福建组培苗3种杉木苗进行造林对比试验,调查1 a和3 a生长量性状.结果表明:西山良种苗、福建组培苗造林1 a和3 a生的地径、树高和冠幅显著高于对照.西山良种苗造林的地径、树高和冠幅增长量比对照分别高14.24%,34.28%和12.85%,福建组培苗高出12.88%,17.92%和23.99%;良种苗造林初期生长迅速,树高-地径生长呈线性相关;采用良种造林能显著提高幼林生长量,从而提升造林成效,可推广到生产实践中.In order to compare the effect of afforestation of superior variety of Cunninghamia lanceolata, 3 varieties of Cunninghamia lanceolata seedlings were selected for comparative test in Jingxi,Guangxi province,and the growth characters of 1 a and 3 a were investigated. The results showed that tree height,ground diameter and crown width with 1 a and 3 a of Xishan generation orchard seedlings and Fujian tissue culture seedlings were significantly higher than those of local common seedlings （ CK） . The growth of tree height,ground diameter and crown width of Xishan generation orchard seedlings forest were 14. 24%,34. 28% and 12. 85%,respectively, while that of Fujian tissue culture seedlings were 12. 88 %,17. 92 % and 23. 99 % higher than of CK. The growth of superior varieties was rapid at the early stage of afforestation, and the tree height-ground diameter growth curve was linear.
