Xiaoxing’anling forest is one of the key forest areas in China. In the past, it implemented the wrong policy of re-mining and rebuilding, with a serious imbalance in the proportion of mining and breeding. Therefore, it is necessary to do well in the construction of poplar timber forest base in forest area, Continue to achieve the sustainable use of great significance .One, to create poplar forest to poplar and poplar main Xiaoxing’anling development of poplar should be the local native tree Poplar mainly Populus plantation grow rapidly, early maturity, yield High, under good site conditions, 25 to 30 years of hectare of up to 300 ~ 400 cubic meters of accumulated volume, reaching the harvest age.Will Ling forestry experimental bureau in 1965 to create 10 hectares of poplar plantation (8% 20% for the big blue
