摘　　要：根据杉木子代性状分离遵循的遗传生长规律,应用杉木高世代种子园良种子代在Ⅲ～Ⅵ类立地造林,选择具有速生表现与较强生长适应性的优势木且未间伐林分作为预选林分,采用树高与地径作为评价指标,利用"t"检验选择法确定优株筛选标准,筛选耐瘠薄-速生优株13株。所选择优株树高与地径生长量与所在样地林分平均木比较有很好的适应性,生产应用价值较高。Based on the genetic rules guiding the character isolation of Cunninghamia lanceolata filial generation,the preliminary stands of plus trees with strong adaptability and rapid-growth performance without thinning felling were selected from the plantations of the filial offspring of fine provenance of C.lanceolata on Ⅲ-Ⅵ grades of site conditions.13 elite infertility tolerant and rapid-growth progenies were selected by means of applying the ＂t＂ determination principle method by taking tree height and basal diameter as evaluation criteria.The growth of tree height and basal diameter criteria of the elite saplings was much higher than that of the average saplings,indicating that the elite plants would be of great application potential to timber production.
