摘　　要：在云南省保山市隆阳区国营林场长岭岗营林区开展了史密斯桉母树林营建技术研究,结果表明:建立史密斯桉母树林要以优良种源选择为基础,并在立地条件较好、交通便利的地块组织实施;依次按50%、40%、40%的疏伐强度进行3次疏伐管理,母树林合理保留密度约270株.hm-2。7年生史密斯桉母树开始开花,花期10—12月,预计种子将于11月一翌年1一2月趋于成熟;母树平均胸径23.1 cm,平均树高17.4 m,平均冠幅7.9 m,长势十分理想。可为史密斯桉的大面积推广种植提供借鉴和参考。Based on excellent seed source,seed stand of Eucalyptus smithii were constructed in the better site with convenient communication,and thinned by intensities of 50%,40% and 40% successively,the density of seed stand was confirmed for 270 trees per hectare.The results showed 7-year-old seed stand would flower,florescence was from Oct.to Dec.,and seed would maturate from Nov,2012 to Jan or Feb,2013.The characteristics of seed stand included average diameter was 23.1 cm,average tree height was 17.4m,and average crown length was 7.9m,.Growth status was ideal and could be referenced to large acreages growing.
