湖北省太子山林场 24个栎树引种试验初报

Introduction Experiment of 24oak species in Taizi Mountain Forest Farm of Hubei province

摘要:

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。

Abstract:

In order to enrich oak resources, its species suitable for cultivation were selected in hubei Taizi Mountain for- est farm . In 2015,24representative oak species were collected from home and abroad to study their growth and adapta- bility in the hilly area of Hubei province . The results showed that the five tree species (Quercus . lyrata , Q. redskins, MS Q. nuttalliiplamer , Q. shumardii, LAQ. nuttalliiplamer) had strong adaptability in Taizi Mountain area, the adapta- bility of 7 tree species,Q. alba ,Q. falcate,Q. palustris,Q. laurifolia ,Q. nigra ,Q. liaotungensis,Q. guyavaefolia , the 9 tree species such asQ. songjiangfabric , Q. lyrata , Q. velutina ,Q. redskins,MSQ. nuttalliiplamer,Q. shumardii, LA Q. nuttalliiplamer,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 MSQ. ,Q. shumardii and LAQ. turn Red in autumn, and their leaves stay longer . They can also be used as landscape trees .
