Abstract:A new circultion method of vegetative propagation of Populus tomentosa and Populus hopeiensis have been studied and developed for 6 years. This method. Of propagation does not need any chemical treatment and plastic cover on the nursery bed for cuttings. The survial percent age of cuttings of the two poplars species steadily keeps 80% or over. And a new root shoot-suckers-reproduction method has been made. The successful propagation of the poplars provided much progress for clonal test, clonal breeding and clonal afforestation of the selected trees of the two poplar species.
