摘　　要：以闽楠6种不同规格容器苗营造的试验林为对象,分析造林当年的幼林生长情况。结果表明:采用不同苗龄和规格的闽楠容器苗造林,对造林成活率的影响不显著,对造林当年地径和树高的影响极显著;其地径和树高随着时间的推迟呈现上升趋势,其中1~3 a的Ⅰ级容器苗造林后地径和树高均高于同苗龄Ⅱ级苗。3 aⅠ级苗的当年地径生长量最大,达5.86 mm,1 aⅡ级苗的地径增长倍数最高,高出原地径1.48倍;树高生长量、增长倍数均以1 aⅡ级苗为最高,达20.15 cm,高出原树高0.77倍。结合造林成活率、地径生长量、树高生长量进行综合评分,3 aⅠ级苗造林的综合评分最高,达0.7658;2 aⅠ级苗次之,得分为0.5905。因此,从生长指标方面分析,Ⅰ级苗造林效果普遍优于Ⅱ级苗,选用3 a闽楠容器苗中苗造林效果好。The young plantation growth in the same year of six different specifications container seedlings afforestation in Phoebe bournei（Hemsl.） Yang was analyzed.The results showed that the effect on afforestation survival rate was not significant,and the effect of different specifications container seedlings on the ground diameter and tree height of P.bournei（Hemsl.） Yang was extremely significant.The ground diameter and tree height of different seedling age and specifications container seedlings were increased with the time delay,and the ground diameter and tree height of 1~3 a container seedlings gradeⅠwere higher than the same age seedlings gradeⅡ after afforestation.The one-year ground diameter growth of 3 a seedlings gradeⅠwas the highest,up to 5.86 mm.The ground diameter growth factor of 1 a seedlings gradeⅡwas the highest,which was 1.48 times higher than the original ground diameter.The tree height growth and growth factor of 1 a seedlings grade Ⅱ were the highest,up to 20.15 cm,0.77 times higher than the original tree.The comprehensive score of 3 a seedlings grade Ⅰ was the highest,up to 0.7658,2 a seedlings grade Ⅰ followed by 0.5905.Considering the growth index,it can be seen that the afforestation effect of seedlings gradeⅠis generally better than that of gradeⅡ.And the afforestation effect of using 3 a medium container seedlings in afforestation of P.bournei（Hemsl.） Yang is good.
