摘　　要：在170多个杨树无性系苗期选择的基础上,在湖区内垸进行了3次共有56个无性系参与的对比试验,主要依据4或5年生的材积生长量,提出中驻6、中潜3、NL-80121等6个南方型黑杨无性系可与原有的中汉17等无性系一同在湖区推广应用。对引进的极具增产潜力的新1等5个杨树新无性系的早期速生性能进行了测定和比较。Experiments on introducing poplar were based on 170 poplar clone seedling stages and choosing 56 clone stages in 3 times in contrast experiments,and the volume increment of 4 or 5 years poplar.The zhongzhu 6,zhongqian 3, NL80121, six southern poplar clone varieties and zhonghan17 clone variety were found to be superior varieties for plantation in lake area.Experiments included testing and contrasting early rapid growth characters of 5 new poplar varieties.
