摘要
为了增加小陇山林区造林树种多样性,从德国引进欧洲白蜡种子育苗,多点营造试验林。结果表明,在小陇山林区,欧洲白蜡遭受晚霜冻害可以2次发芽正常生长;在优良立地上13 a生开花结实,具备建成人工栽培种群的基础;在优良立地上平均树高可达8.4 m,平均胸径可达7.6 cm,有望成材,但在原生植被为杂灌林的立地上长势不良,有可能长成小老头林。
In order to increase the diversity of tree species in Xiaolongshan forest area, Fraxinus excelsior seeds were introduced from Germany to cultivate seedlings, and experimental forests were built at many points. The results showed that the Fraxinus excelsior could germinate and grow normally in Xiaolongshan forest area. Under the good site conditions, 13-year-old Fraxinus excelsior can blossom and bear fruit, which is the basis for the establishment of artificial culture population. The average height of trees can reach 8.4 m and the average diameter of chest can reach 7.6 cm, which are expected to be mature. However, on the site where the original vegetation is mixed irrigation forest, the growth trend is poor, and it is possible to grow into a small old man forest.
