| 摘 要： | 通过对三代实生与萌芽杉木生长特性的比较分析，结果表明：三代萌芽杉木早期生长量显著快于实生杉木，但树高在２５年生后、胸径和单株材积在１０年生后出现明显衰退，但至２８年生时这种衰退状况得到一定程度恢复。这体现了三代实生和萌芽杉木在土壤肥力退化较为严重状况下生物学特性的差异。

| Abstract: | The growth characteristics of third planting Chinese fir of seedling stand and sprout forest were comparatively analyzed, the result showed that the increment of third planting Chinese fir of sprout forest was larger than seedling stand in early years, but the increment of tree height after 25-year-old, diameter and tree volume after 10-year-old distinctly declined, and recovered to a certain extent when 28-year-old. All above reflect the biological characteristics difference of third planting Chinese fir of seedling stand and sprout forest on the seriously degraded soil. |
