为选育适合当地林业生物质能源发展的杨树品种，须确定最佳的栽植密度。伊犁州林木良种繁育试验中心于2013年开展试验。选取本地13个优良杨树品种，分别在2 m×0.5 m、3 m×0.5 m 和2 m×1 m 等3种栽植密度下进行试验，经过2年的试验调查，结果表明：3 m×0.5 m 栽植密度较适合杨树能源林的生长，大叶钻天杨、I-467和 I-262较适合林业生物质能源发展的要求。

In order to select optimal varieties of poplar to suit the development of local forestry biomass energy,the optimal density must be determined.Experiments were conducted in Forest Tree Breeding Experiment Center of Yi-li Prefecture in 2013.Thirteen fine varieties of poplar in local area were conducted experiments under three planting densities (2 m× 0.5 m,3 m × 0.5 m and 2 m ×1 m);after two years of investigations,result shows that planting density of 3 m ×0.5 m is more suitable for growth of poplar forest energy;Populus balsamifera ,Populus ‘I-467’ and Populus ‘I-262’is more suitable for developing forestry biomass energy.
