The difference of planting survival rate was not insignificate between Populus alba×berolinensi and cathay poplar. In the earlier phase and later phase of afforestation,growth of Populus alba×berolinensi was higher than cathay poplar. And the cold tolerance and diseases and insect pests tolerance were semblable.
