摘　　要：为了探索白榆品种‘阳光女孩’嫁接繁育方法,同时对嫁接方法不同造成嫁接部位留下拐角的问题进行研究,试验选用地径0.6 cm白榆为砧木,设计L9(33)正交试验,结果表明:嫁接繁育的最佳处理是选取1年生枝条中部作为接穗,在4月上旬进行切接;芽接方法可有效地避免形成拐角苗木,成活率80.2%;切接方法中采用留接穗上靠近接口最近的内侧芽也可有效克服拐角现象,提高植株主干通直度,保证其较高的生长量,成活率可达86.9%,高于芽接。The paper aims to study a grafted breeding method of Ulmus pumila cv.‘Yangguang Nvhai＇,meanwhile, research different grafting methods which could cause the problem of the corner on grafting part.The author chose Ulmus pumila of diameter 0.6 cm as rootstock and carried out L9（3^3） orthogonal design test.The result showed that the optimal treatment in the experiment was using the middle of annual branches as thescion and cutting in early April; the budding method could effectively avoid the corner seedling, the survivalrate was 80.2%; the cutting method could also effectively avoid the corner phenomenon by using the bud on thescion and near the interface, improve the trunk straight through degrees and ensure its high growth rate, thesurvival rate was 86.9%, higher than the budding.
