湖北省太子山林场24个栎树引种试验初报

Introduction Experiment of 24 Oak Species in Taizi Mountain Forest Farm of Hubei Province

为丰富栎树资源,筛选出适应湖北中部低山丘岭岗地栽培的栎树种,2015年从国内外收集引种具有代表性的24个栎类树种在湖北省太子山林场开展生长量及适应性研究。结果表明:琴叶栎、红皮栎、纳塔栎MS、舒玛栎、纳塔栎LA等5个树种在太子山地区适应性较强;美洲白栎、南方红栎、沼生栎、月桂叶栎、水栎、国产辽东栎、大斗栎等7个树种适应性较差;松江白栎、琴叶栎、黑栎、红皮栎、纳塔栎MS、舒玛栎、纳塔栎LA、松江麻栎、小叶栎等9个树种平均生长量较高、适应性强,可作为该地区荒山造林用树种,其中纳塔栎MS、舒玛栎、纳塔栎LA秋季叶色变红,叶片留树期较长,亦可作为园林景观用树种。

In order to enrich Oak resources,its species suitable for cultivation were selected in hubei Taizi Mountain forest farm.In 2015,24 representative Oak species were collected from home and abroad to study their growth and adaptability in the hilly area of Hubei Province.The results showed that the five tree species(Quercus.lyrata,Q.redskins,MS Q.nuttallii plamer,Q.Shumardii,LA Q.nuttallii plamer)had strong adaptability in Taizi Mountain area,the adaptability of 7 tree species,Q.alba,Q.falcate,Q.Palustris,Q.laurifolia,Q.nigra,Q.liaotungensis,Q.guyavaefolia,the 9 tree species such as Q.Songjiang fabric,Q.lyrata,Q.velutina,Q.redskins,MS Q.nuttallii plamer,Q.Shumardii,LA Q.nuttallii plamer,Q.Songjiang acutissima and Q.variabilis have higher average growth and strong adaptability,which can be used as afforestation tree species in this area.Among them,leaves of MS Q.,Q.Shumardii and LA Q.turn Red in autumn,and their leaves stay longer.They can also be used as landscape trees.
