Abstract

Investigation were made of the species, distribution, and growth situation of Eucalyptus trees and their utilizing situation of industrialization in Guangyuan. It was found that Eucalyptus robusta Smith, and Eucalyptus tereticornis Smith,etc. planted since the 1960s experienced a hazardous frost at -8℃ in 1976. Most of the survivals in the frost and the later-planted Eucalyptus trees grew at the altitudes from around 450 m to 600 m and the breast-height diameters could reach 20 cm to 50 cm. In Guangyuan,Eucalyptus robusta Smith suffered more from freezing injury and windstorm disaster than Eucalyptus tereticornis smith. The growth of Eucalyptus urophylla which was introduced for test has been affected by the freezing injury since 2007. Due to the dual effect of freezing injury and windstorm disaster,it is suggested that,exploring the frigorific mechanism of Eucalyptus can help to further develop breeding or introducing the cold-resistant, wind-resistant and fast-growing varieties which are suitable for growing in Guangyuan.
