| Abstract: | Investigating the growth status of Eucalyptus dunnii in central Hunan Province,this paper demonstrates that it grows at a rate of about 1.5 to 2 meters per year with its diameter around 2 to 3 centimeters,and has a great ability for infertile-resistance,cold-resistance and rapid growth.Concisely summarizing the breeding techniques of Eucalyptus dunnii seedlings,the paper also puts forward some solution to the existing problems. |
