1998年春，在西北林学院苗圃利用（银白杨×毛白杨）×新疆杨的37个无性系1、2年生杂种苗进行蜡封扦插试验。6月下旬调查扦插成活率平均为99.6％，比作为对照的户县苗圃1年生毛白杨插穗成活率高34.5％，现将该技术介绍如下。1整地与作床将圃地深翻约30cm深，然后耙磨整平作成长
In the spring of 1998, the wax seal experiment was carried out in the nurseries of the Northwest Forestry College using the 1, 2-year-old hybrid seedlings of 37 clones of Xinjiang poplar (Populus × Populus × Populus × Populus × Young Poplar). The average survival rate of cuttage surveys in late June was 99.6%, which is 34.5% higher than the survival rate of 1-year-old Populus trichocarpa cuttings in nursery of Hu County as a control. The technique is introduced as follows. A site preparation and bed for the bed will be deep about 30cm deep, then harrow grinding leveling for growth
