中华金叶榆嫁接技术研究

Study on Grafting Technology of Ulmus Pumila ‘Jinye’

笔者以青岗坪林场圃地内原有的榆树苗为砧木,以河北省林业和草原科学研究院引入的2年生中华金叶榆嫁接苗为接穗,研究了不同嫁接方法、不同嫁接时间、不同接穗保湿方法对其嫁接成活率的影响。结果表明,嫁接中华金叶榆,以插皮接和劈接效果最好。在青岗坪林场从3月10日至4月30日,都可以对中华金叶榆进行嫁接,以4月20日前较好。中华金叶榆接穗用白蜡封穗保湿效果最好,操作简便,成本低。

Taking the original Ulmus pumila seedlings in the nursery of Qinggangping forest farm as stock and the 2-year-old Ulmus pumila’Jinye’grafted seedlings introduced by Hebei academy of forestry and grassland sciences as scions,the effects of different grafting methods,different grafting time and different scion moisturizing methods on the grafting survival rate were studied.Results showed that for grafting Ulmus pumila’Jinye’,the effect of bark grafting and split grafting were the best.In Qinggangping forest farm,Ulmus pumila’Jinye’could be grafted from March 10 to April 30 and it was better before April 20.The scions of Ulmus pumila’Jinye’had the best moisturizing effect with white wax which method was simple operation and low cost.
