Abstract: The study on the high-yield poplar cultivating pattern in mid-temperate zone in China was reported, which had been used for poplar industrial exploitation on a large scale in Liaoning Province. The results showed that the survival rate of planting amounted to more than 97%, the preservation rate of juvenile tree amounted to 95.7% in an area of 2000hm² located in the colder and arider forestland. The annual average height growth of the juvenile trees was 2.6～3.0m, and the annual average growth of DBH was 2.2～3.7cm, which set a high\|yield record of cultivating poplar in a big area in China. Meanwhile, the better economic benefits have been achieved from intercropping in such cultivation pattern of the high-yield poplar.
