赤桉生长快,材质好,耐寒耐旱性强。为我省金沙江干热河谷。新兴的攀枝花钢城——渡口市城市绿化先锋树种。同时也是盆地主要栽培种类之一。为加速扩大赤桉的发展,研究解决干形不甚通直,进一步提高其速生特性。我所于1973年在渡口市进行赤桉个体选优调查,采用表型五株优势木对比法,以树干通直为主要指标,生长量树高大于10％以上,胸径大于20％,材积大于30％以上的初选标准,选出八个优良单株。为提高选种效果,加速繁殖应用。1974年春,我所选择不同气候类型有条件的林场、苗
Eucalyptus grow fast, good material, cold and drought-resistant. For our province Jinsha River dry hot valley. Emerging Panzhihua Iron and Steel City - ferry pioneer tree species in the city of ferry. It is also one of the major cultivated species in the basin. In order to speed up the development of Eucalyptus grandis, the solution to the problem of dryness is not straightforward to further improve its fast-growing characteristics. I was in 1973 in the city of fermented Eucalyptus individual selection survey, the phenotype of the five dominant wood contrast method, the trunk straight as the main indicator, the growth of the tree is more than 10% high, more than 20% diameter, diameter greater than the volume More than 30% of the primaries, electing eight fine plants. To enhance the selection effect, accelerate the application of reproduction. The spring of 1974, I have chosen different types of climate conditions of the forest farm, seedlings
