粉花山杏嫁接技术研究

Study on Grafting Techniques for Armeniaca sibirica ‘Pink Flower'

选用粉花山杏1年生小枝为接穗,普通山杏1年生苗为砧木作为试验材料,采用4因素3水平正交试验,研究粉花山杏的嫁接成活率。结果表明:影响粉花山杏嫁接成活率最重要的因素是嫁接方法,其次是嫁接时间和接穗处理方式,最后是砧木规格;砧木地径与新梢生长量之间存在着极显著的正相关;采用腹接或劈接的方法,在砧木树液开始流动而芽未膨大之前,将梢头接穗或蜡封上端的梢中接穗嫁接到径粗≥0.7 cm的砧木上,粉花山杏的嫁接成活率能达到90%以上。

Previous year′s twigs of Armeniaca sibirica ‘Pink Flower’ as scions and one year seedlings of common Armeniaca sibirica as rootstocks were chosen to study the grafting survival rate with the orthogonal test of four factors at three different levels in Armeniaca sibirica ‘Pink Flower’. The results indicated that grafting method was the most important factor on grafting survival rate of Armeniaca sibirica ‘Pink Flower’, followed by grafting time and treating scions mode, and rootstock′s diameter had the least impact. Furthermore, the rootstock′s diameter had significant positive correlation with new branch growth. To reach 90% or higher survival rate, the scions with apical buds or the top waxed grafted onto the rootstocks with diameter larger than 07cm when the rootstock sap begins to flow and prior to the buds starting to swell were the key factors by using side grafting or cleft grafting.
