探寻高效、实用、操作简便的嫁接方法,建立科学、有效的嫁接育苗技术体系,以实现辛夷的集约化栽培,进行了辛夷嫁接技术研究.试验结果表明,不同嫁接方法对辛夷成活率影响极为明显,在试验的劈接、舌接、单芽腹接、枝腹接、芽片腹接5种嫁接方法中,单芽腹接成活率(95.5％)最高,劈接成活率(81.7％)次之,舌接成活率(1.5％)最差.在北川地区,不同的嫁接时间对辛夷成活率影响极为明显,在辛夷休眠期间的所有月份中,9月份嫁接成活率最高达到96.5％；其次为10月和2月,嫁接成活率分别为91.3％和85.4％.接穗类型不同,成活率也不同.单芽腹接用中部饱满芽成活率最高(97.1％)；枝腹接用枝条顶芽段成活率(81.6％)最高；劈接用中部饱满芽段成活率(87.1％)最高；在各种嫁接方法中,枝条下部弱芽段均不适合作为接穗.辛夷嫁接3年后开始挂花,5年后可以形成产量,并且树体得到明显矮化,花朵最多可达66朵,鲜重最高可达354.8g/株,比实生苗投产期至少提高10年以上.%In order to seek high-efficient, practical and simple grafting methods, to establish scientific and effective technology system of grafting and raising seedlings, and to achieve the intensive cultivation of Magnolia liliflora Desr. , the grafting techniques of M. Liliflora were studied in experiments. The results showed that the survival rate of M. Liliflora was significantly impacted by different grafting methods, inclu-ding cleft grafting, tongue grafting, single-bud side grafting, shoot side grafting, bud slice side grafting. Of these, the survival rate of single-bud side grafting was the highest (95.5%), followed by cleft grafting (81.7%), and the least by tongue grafting (1.5%'). Thus, single-bud side grafting and cleft grafting were mainly used for M. Liliflora. In Beichuan District, there was also a significant difference in the survival rate of M. Liliflora from different grafting time. During the dormancy of M. Liliflora, the survival rate was the highest in September (96.50%), fol-lowed by October (91.30%) and February (85.4%). The scion types had evident effect on the survival rate of seedlings. The survival rate could reach 97.1% in single-bud grafting with central full bud as a graft, 81.6% in shoot side grafting with terminal bud of shoot as a graft,and 87.1% in cleft grafting with central full bud as a graft. Weak buds on the lower part of shoots were not suitable to be used as grafts. Gener-ally, grafted M. Liliflora took 3 years to flower. After 5 years, each plant could have a maximum of 66 flowers, the fresh weight of which was up to 354.8 g. Compared with seedlings, grafted seedlings could reduce the startup time by more than 10 years.
