在各种植物常规的芽接繁殖中,大家都很习惯地使用当年嫁接,当年剪砧、松绑的处理方法,并自然地认为这是唯一的,也是最好的方法。然而实践证明,在北方地区,尤其是冬季寒冷的地区,对于不少园林、园艺植物品种的芽接繁殖,这种处理方法并不是十分理想的。通过调查了解,我们发现在冬季寒冷的新疆,如果于生长季的6月中旬以后,在一二年生的单瓣榆叶梅上芽接重瓣榆叶梅,在一二年的海棠和榆叶梅上,分别芽接苹果和李子品种,并在成活后当年剪砧和松绑,那么,当年嫁接苗的生长时间就是从6月中旬到9月中旬前后,只有3个月左右,不但生长量不会很大,而且木质化程度也不会太高,很容易受冬季严寒和来年倒春寒的侵袭,形成冻梢或大半部枝条冻死的现象,从而影响 In all kinds of plants conventional bud reproduction, we are accustomed to use that year grafting, then cutting anvil, loose handling, and naturally that this is the only, but also the best way. However, practice has proved that in the northern areas, especially in the cold winter areas, for many garden, horticultural plant species bud reproduction, this treatment is not very satisfactory. Through investigation, we found that in the cold winter of Xinjiang, after the mid-June of the growing season, the petals of Prunus trilobata grow on the biennial leaves of 12-year-old Prunus triloba, , Respectively, budding apple and plum varieties, and in the survival of the year after the cut anvil and loose, then the growth of grafted seedlings from mid-June to mid-September before and after, only about 3 months, not only the growth is not large , But also the degree of lignification will not be too high, it is easy to winter cold and the coming winter cold invasion, the formation of frozen tip or most of the frozen branches of the phenomenon, thus affecting
