河北杨、新疆杨速生丰产栽培试验

Test on Planting of the Fast-Growing and High-Yield Forest of Populus hopeiensis and Populus alba var. pyramidalis

大力营造河北杨速生丰产林是兴电灌区风沙沿线防风治沙重大决策，该地区蛀干害虫天牛严重危害杨树和其它树种，河北杨、毛白杨等是较好的抗天牛树种。栽培速生丰产林是生产木材的主要途径。

The plantation of fast-growing and high-yield forest of Populus hopeiensis,as main ways of producing timber, plays a important role in preventing wind-sand in Xingdian Irrigated Area. This study indicated that Populus hopeiensis and Populus tomentosa have hign resistence to Longicorns.
