嫁接育苗,一般在春、秋两季。春季嫁接最好在砧木树液开始流动到砧木形成层与木质部分离之前,在新疆约当3—5月初;秋季嫁接宜在树木生长渐趋缓慢,约8—9月。具体时间因各地气候、树种生物学特性和嫁接方法不同而异。 现选几种主要的嫁接方法介绍如下: (一)芽接。选取母树的一个芽片接穗进行嫁接繁殖的方法,叫做芽接。这种方法经济、简便、工效高、成活率高、应用广泛。芽接在整个生长季节内,皆可进行。但依(?)芽的形状和砧木开口的方式不同,又可分为“丁”字形芽(?)、方块芽接、套芽接等。
Grafting nursery, usually in spring and autumn. Spring grafting is best in the rootstock sap flow began to rootstock formation and xylem before the separation, in Xinjiang in early March-May early; autumn grafting should be slower in the growth of trees, about 8-9 months. The specific time due to the climate, species biological characteristics and grafting methods vary. Now choose several main methods of grafting introduced as follows: (a) Budding. Select a shoot of the mother tree scion graft method of grafting, called Budding. This method is economical, simple, high efficiency, high survival rate, widely used. Budding in the entire growing season, can be carried out. However, depending on the shape of the root shoots and the opening of the rootstocks, they can be classified into “Ding” shaped buds (?), Square buds and buds.
