大别山区黄色类杉木可以划分为翘鳞、松鳞和紧鳞三种类型。作者调查了马宗岭和天柱山的8片10—20年生林分以及茅山80株60年生单株,并作了各类型的树干解析和木材密度测试。结果表明,三种类型,在球果直径、苞鳞数目、苞鳞形状等球果特征,以及在枝下高、节间距、树皮厚度、针叶密度和长度等形态特征上均有显著差异。诸类型的生长特性差异明显,胸径、树高和材积生长都呈现松鳞类型早期速生、紧鳞类型后期速生的趋势;而且紧鳞类型的木材密度显著地大于其它两种类型。松鳞类型可以用作营造中小径级速生林,紧鳞类型可以用作营造大径级优质丰产林,松鳞类型具有特殊的利用价值。
Dabie mountain yellow fir can be divided into Alice scale, pine scale and tight scale three types. The authors investigated 8 10-20-year-old stands of Mazongling and Tianzhushan and 80 60-year-old single plants of Maoshan, and conducted various tree trunk analyzes and wood density tests. The results showed that there were significant differences among the three types in conical characteristics such as cone diameter, bract scale, bract scale shape and morphological characteristics in branch height, pitch spacing, bark thickness, needle density and length . The growth characteristics of different types were obviously different. The DBH, tree height and volume growth all showed the trend of rapid growth at the early stage of Pinus sylvestris and the rapid growth at the later stage of tight scales. And the density of tight - scales was significantly greater than that of the other two types. Pine-scale type can be used to create medium and small-diameter fast-growing forest, tight-scale type can be used to create large-diameter high-quality high-yield forest, pine scale type has a special value.
