摘要
为了挽救、保存、利用处于濒危灭绝的树种,以厦门同安祥溪国有林场为试验点,从国内外引进热带亚热带的优良珍贵树种45科145种,有133种在祥溪国有林场育苗定植成功,目前存活的树种有80多种,对47种未得到开发利用的珍贵树种进行深入研究,其中长势优良的有29种,占61 7%,能正常开花结实传宗接代的有32种,占68 1%,可为树种改良和提高遗传增益提供大量的选育材料。采用聚类分析的方法,根据各引种树种的综合评分,选择出塞楝、灰木莲、团花、鸡尖、象耳虫、沙椤等13个适应性强、速生的用材树种,适合于闽南山地种植。
In order to save,preserve and utilize the endangered and extinct tree species,45 families 145 species of tropical and subtropical fine and rare tree species were introduced from abroad,the seedling raising and fix planting of 133 species succeed in Xiangxi National Forest Farm,there are 80 and more tree species exist at present,47 rare tree species which aren't developed and utilized were studied thoroughly,among which 29 species with fine growth vigours exist and account for 617%,32 species which can abloom and fruit account for 681%,which may provide a large amount of selective materials for tree species improvement and increasing genetic gain.
