摘　　要：绣球荚蒾不结种子,种苗来源比较困难。开展绣球荚蒾不同季节扦插繁殖试验,提高扦插成活率,为绿化提供种苗繁育技术支撑,具有重要意义。绣球荚蒾扦插最佳季节为夏季5月,生根率达到92.5%;其次为秋季9月,生根率达到75.8%;第3为冬季,生根率达到67.2%;最差为春季,生根率仅为50.3%。夏季比春季扦插成活率高42.2%。该结论对充分利用稀少的绣球荚蒾种质资源,为社会提供大量绿化苗木具有现实意义。Viburnum macrocephalum can＇ t produce seed, therefore it is difficult to raise seedlings. It is important to study the cutting propagation of If. macrocephalum in different seasons to improve the rooting rate, so as to provide seedling propagation technique for the greening industry. The optimal season for the cutting propagation of If. macrocephalum was summer （May）, providing 92.5% rooting rate; the next was autumn （September）, providing 75.8% rooting rate; the third was winter （December）, providing 67.2% rooting rate; the worse was spring （March）, providing 50.3% rooting rate. The rooting rate in summer was 42.2% higher than that in spring （March）. This technique is important to make the best use of rare E macrocephalum resources and to provide plenty of seedlings for greening industries.
