摘　　要：采用全光照喷雾技术,进行了杂种马褂木嫩枝扦插繁育探索。选用不同扦插基质、不同浓度的IBA生根粉、不同木质化程度的插穗进行了对比试验,结果表明:在珍珠岩基质中,选用未木质化的顶芽做插穗,对插穗进行留半叶和摘心处理以及扦插用200 mg·L-1的IBA速蘸处理时,其扦插效果最好,生根率达到了81.7%。The trial of softwood cutting techniques of Hybrid Tulip Tree was conducted under full spraying. compared with different Mediums, Different Concentration of IBA and different xylem branch The results showed that： In Perlite medium, non-lignified terminal bud treated by half leaf, Pinching and dip quickly in 200 mg·L^-1 IBA, The rooting rate is 81.7%.
