摘　　要：无机盐浓度较低的WPM培养基是钻天柳组培比较适合的基本培养基;休眠枝水培腋芽萌动后剥除芽鳞的带芽茎段及单芽是较适合的培养材料,腋芽诱导率最高可达85%;在6BA0.5 mg/L+NAA0.2 mg/L条件下,增殖系数最高可达到5.7;聚乙烯吡咯烷酮有助于钻天柳诱导生根,WPM+IBA0.6 mg/L+PVP20.0 mg/L条件下,诱导生根可高达13%。The WPM medium with lower inorganic salt concentration was suitable for the basic culture medium. The stem with bud or single bud, when the bud scales were divested after the axillary bud stirring of hdroponic dormant branches, was suitable for the cultivation of the material, axillary bud induction was rate up to 85%. In the condition of hormone combination 6 ba 0. 5 mg/L ＋ NAA0. 2 mg/L, the highest multiplication factor can achieve 5.7. PVP （polyvinylpyrrolidone） induced to take root. Under the condition of WPM ＋ IBA0.6 mg/L ＋ PVP20.0 rag/L, rooting rate can reach 13%.
