李树优良砧木选择试验研究

Study on the selection of superior rootstocks for plum trees

通过对张掖市小红李、榆叶梅等5种李树砧木根皮率、树高、冠径、嫁接亲和性、生长与结果测试分析,认为本地实生小红李、榆叶梅为李子良种的优良砧木,榆叶梅有一定的矮化性,适于密植;山桃次之;毛桃不适于作抗寒性差品种的砧木;山杏作砧木,盛果期李子品质下降,忌大面积推广。

The paper analyzing the percetage of root bark, tree height, crown diameter, graft compatibility and growth of five plum tree’ s rootstocks such as small red plum and flowering plum etc. The small red plum and flowering plum are good rootstocks for plum. Dense planting is suitable for flowering plum because of its dwarfed nature. Wild peach can’t be used as rootstock for species which had poor cold resistence. Taking apricot as the rootstock resulted in a decline in plum quality in full fruit period, so apricot can’t be popularized.
