摘要
珍贵树种家系测试优选是营建母树林的基础工作。为筛选油杉适生区域,推广油杉造林,分别在以1#、4#、6#、7#、27#等5个油杉家系为对象,在福建大田梅林、永春碧卿、华安西陂3个林场营建子代测试验林,通过8 a龄单株材积选择速生家系。结果表明,3县最优家系各异,梅林、碧卿最优家系均为4#、6#、7#、27#家系;西坡5个家系速生性能相近,所选家系可用于营建母树林,满足相应邻近地区油杉造林用种需求。
Family testing of precious tree species is the basic work of building mother forest.In order to screen the suitable areas of Keteleeria fortunei and promote Keteleeria fortunei afforestation,five Keteleeria fortunei families(1#,4#,6#,7#and 27#)were set up in three forest farms(Meilin,YongchunBiqing and Hua’An Xipo,Datian,Fujian),and fast-growing families were selected by 8 a year old individual tree volume.The results showed that the optimal family lines of Meilin and Biqing were 4#,6#,7#and 27#.The five families in the west Slope had similar growth performance,and the selected families could be used to build mother forest to meet the needs of Keteleeria fortunei afforestation in the adjacent areas.
