【摘要】 经过近100年的引种历史,四川共收集了130余种桉树,目前仍保留有近40种桉树。这些树种在四川省的林业建设中发挥了重要作用。在四川具有发展前途的桉树有:巨桉、直干兰桉、柳桉、史密斯桉、邓恩桉、迪恩桉、亮果桉、赤桉、大花序桉、尤曼桉等。根据桉树生物学特性以及四川多年来桉树栽培情况,将四川桉树栽培地区划分为盆地、攀西河谷阶地和干热河谷等三个栽培区。针对不同的栽培区,提出相应的适宜桉树种,并对巨桉、直干蓝桉、赤桉树种不同培育目标的栽培技术进行了总结。更多还原

【Abstract】 More than 130 species of Eucalyptus were collected in Sichuan after about 100 years of introduction.There were about 40 species of Eucalyptus survived,which played an important role in forestry development of Sichuan province.Some of Eucalyptus can be developed in Sichuan,Such as E.grandis,E.maidenii,E.saligna,E.smithii,E.dunnii,E.deanei,E.nitens,E.camaldulensis,E.cloeziana,and E.youmanii,and so on.According to the climate in Sichuan and biology characters of Eucalyptus,three cultured Eucalyptus areas can be divided,which are basins,river valley land in Panxi and dry-hot river valleys.Adaptive species are put forward to different areas.Cultural technologies of E.grandis,E.maidenii and E.camaldulensis are also summarized in this paper.更多还原
