通过对引进巨尾桉无性系与巨桉、尾叶桉进行山地造林试验３年的研究结果表明，巨尾桉无性系不仅能适宜本地区山地栽培，而且生长快，３年生平均树高１２１ｍ，胸径１２３ｃｍ，单株带皮材积００７２８ｍ３，去皮材积００５７４ｍ３，比尾叶桉分别增长２３５％、２８１％、９２１％和１４０２％，比巨桉分别增长１３１％、１９４％、５６６％和５１５％。它还具有树干通直圆满、树皮较薄、冠径比小、出材率高、丰产性好等特点，可以大面积发展，并总结出栽培上的关键技术。 The results of three-year experiment on afforestation of Eucalyptus grandis × E. grandis clone and Eucalyptus grandis × E. grandis showed that the clones of Eucalyptus grandis × E. grandis could not only be suitable for mountainous cultivation in this area but also grew fast with an average tree height of 12 years 1m, diameter at breast height 123cm, single plant with 0.0728m3 skin material and 00574m3 skin material, respectively, which increased by 235%, 281%, 921% and 1402% respectively than that of Eucalyptus urophylla Eucalyptus increased by 131%, 194%, 566% and 515% respectively. It also has the features of trunk straight round, thin bark, small crown-diameter ratio, high yield, good yield, etc. It can develop in large area and sum up the key cultivation techniques.
