Abstract: In order to explore key cultivation technology of Populus euramericana‘Quanhong’ , a research on it was carried out with methods including shading, irrigation with snow-melting agent, pigment measurement, material analysis, stock selection and field observation. The results showed that there were two peaks on the curve of diurnal variations of net photosynthetic rate of Populus euramericana‘Quanhong’ ; the tree could not tolerate high basking, but performed better in shade- tolerance. Hence, it grew well in slight shading area. Furthermore, Populus euramericana‘Quanhong’was resistant to snow-melting agent to a certain extent, and could be used as border trees. In addition, index values of Populus euramericana‘Quanhong’were just second to that of Populus × canadensis Moench, and therefore, Populus euramericana‘Quanhong’could be used for timber forests. The optimal stock was Populus cathayana, for which the grafted trees grew straight and tall, whose bark was dark grey or greenish and crown was purplish red, thus could add more colors to the landscape.
