摘　　要：新疆杨属于难生根的树种,在乌兰察布地区利用硬枝直接扦插成活率不足30%,严重制约着该树种的扩繁工作。经过多年试验表明,采取对插穗进行催芽处理等一系列育苗技术措施,可使新疆杨硬枝扦插成活率提高到80%-95%。Populus bolleana is a kind of tree species difficult to root. The survivalratio of Populus bolleana with cuttage by hard branch directly is less than 30 % in Wulanchabu district, which seriously restrict the reproduction of Populus bolleana. After many--year experiments, the result show that bud forcing treatment can increase the survival ratio of Populus bolleana with cuttage by hard branch up to 80%-95%.
