摘要
通过调查福安市引种的桤木、红锥、米老排、拟赤杨、闽奥栲、光皮桦等6种阔叶树造林3a后的生长情况,结果表明各树种在1-3年生时高生长快,长势良好,以2年生桤木生长量最大,树高达3.26m,地径达5.12cm;6种阔叶树均非乡土树种,但引种后早期生长表现良好,具有较强的防寒防冻抗病虫害能力.
The growth of introduced broadleaved trees (Alnus cremastogyne,Castanopsis hystrix,Mytilaria lao-sensis,Alniphyllumfortunei,Castanoptisfissa &Betula luminifera )were investigated in Fuan City after three years.Result shows that all sapling trees have the characteristics of fast height growth and optimal growth;2-year-old Alnus cremastogyne have the maximum growth,tree height and ground diameter being 3 .2 6 m &5 .1 2 cm.Six kinds of broadleaved trees are non-native species;their growth performed optimal in early stage after the introduc-tion,with strong cold-resistance,frost-resistance & pest resistance.
