在澳大利亚的原始森林中,桉树的数量比例越来越高。在澳洲的南部,桉树甚至主宰了整个森林。桉树与其他树种相比,生命力并不顽强。它的根系扎入土壤并不深,枝干繁殖也较缓慢。但在原始森林,作为弱者的桉树能够在万木丛中胜出,实在令人惊讶。澳洲的植物学家研究了桉树生长需要的土壤、水分、环境等因素,也没有得出具有逻辑性的结论。最后,有一种被人忽视的因素 The proportion of eucalyptus in the native forests of Australia is increasing. In southern Australia, eucalyptus even dominates the entire forest. Eucalyptus compared with other species, vitality is not tenacious. Its roots tied into the soil is not deep, branch propagation is also slower. However, in primeval forests, eucalyptus as a weak can win out among 10,000 trees, which is really surprising. Australian botanists have studied the eucalyptus growth of soil, water, environment and other factors, did not come to a logical conclusion. Finally, there is a neglected factor
