西鹃生长慢、株型小,大都采用高接法繁殖,以获得较大的植株。嫁接西鹃按时间可分为春接、夏接和秋接;按砧穗形式可分为老枝接老枝、新枝接新枝和老枝接新枝,其中以新枝接新枝成活率最高,愈合时间最短。嫁接方法有切接、劈接、腹接和靠接等。在砧木粗于接穗时,一般采用切接或腹接;在砧穗等粗时采用劈接;西鹃新枝嫁接方法简单,成活率高,靠接一般较少采用,但可用自身靠接进行造型补缺和繁殖名贵品种。其中以切接法使用最多,以植株顶端、强枝、新枝部位的嫁接为最好。如何把诸因素有机地结合起来,便是嫁接成功的关键。西鹃嫁接,砧木一般多采用大叶毛鹃,株型较好的夏鹃也可以,但接穗品种必须与夏鹃长势相同,如‘王冠’、‘寒柏牡丹’等,不宜选用长
Rhododendron growth is slow, small plant type, most of the high access to breeding, in order to obtain larger plants. Grafted rhododendron by time can be divided into spring, summer and autumn; according to the form of anvil can be divided into the old branch to pick the old branch, the new branch to the new branch and the old branch to the new branch, of which the new branch to the new branch survival rate of the highest, healing time The shortest. Grafting methods are cut access, split access, abdominal access and docking and so on. When the rootstock is thicker than the scion, the cuttings or the abdomen are generally used; when the rootstock is thick, the split is adopted; the new branch of the rhizome is simple in grafting, the survival rate is high, the connection is generally less and less used, Make up and breed valuables. Among them, the most commonly used to cut the law, the top of the plant, strong branches, the new branch of the graft as the best. How to organically combine the factors is the key to the success of grafting. Rhododendron grafting, rootstocks generally use big leaf Cuckoo, plant type better summer cuckoo, but the scion varieties must be the same with summer cuckoo, such as ’crown’, ’arborvitae Peony’, etc., should not be used long
