摘　　要：为探索紫椴嫩枝扦插繁育技术,加快紫椴繁育进程,以紫椴当年生嫩枝为材料,研究了植物生长调节剂及其浓度、处理时间对紫椴嫩枝扦插的影响。结果表明,1500 mg/L的ABT1号生根粉速蘸处理下,紫椴扦插苗的平均生根率可达75%,平均生根数3.1条,平均根长13.3 cm,为紫椴嫩枝扦插的最佳处理。In order to improve the survival rate of Tilia amurensis softwood cutting and speed up the breeding process,the effects of plant growth regulator,concentration and treatment time on Tilia amurensis softwood cutting were studied.The results showed that under the treatment of 1500 mg/L ABT1 rooting powder,the average rooting rate of Tilia amurensis cuttings is 75%,the average rooting number is 3.1,the average root length is 13.3cm,which is the best treatment of Tilia amurensis cuttings.
