摘　　要：为了探索光皮树嫩枝扦插繁殖技术,以光皮树当年生嫩枝为插穗,研究了不同基质、不同扦插时期、不同生根剂及不同保湿处理措施对光皮树嫩枝扦插生根的影响情况。试验结果表明:基质、扦插时期和生根剂均可明显影响光皮树嫩枝扦插的生根效果,其中扦插基质以珍珠岩为最佳,扦插时期以8月中旬为最好,生根剂以200 mg L-1的IBA为最好,其生根时间短,生根率能达到90%以上;在保湿效果方面,全光照喷雾保湿比塑料拱棚封闭保湿更有利于光皮树嫩枝的生根。In order to explore techniques of softwood cutting in Comus wilsoniana, selecting annual softwood in C. Wilsoniana as cuttings, effects of different media, cutting periods, rooting agent and scion moisturizing treatments on softwood cutting rooting were researched. The results show that medium, cutting period and rooting agent obviously influence effect of softwood cutting rooting, and the effect is the best, rooting time is short and rooting rate can reach above 90%, under the conditions of perlite as medium, 200 mg · L^-1 IBA as rooting agent, and mid-August as cutting period. The full-illumination spraying moisturizing treatment is more help for softwood rooting than the closed moisturizing treatment of plastic arched shed.
