In order to seek high-efficient,practical and simple grafting methods,to establish scientific and effective technology system of raising seedlings by grafting,and to achieve the intensive cultivation of Magnolia liliflora Desr.,the grafting techniques of M.liliflora were studied through experiments,including cleft grafting,tongue grafting,single-bud side grafting,shoot side grafting,and bud slice side grafting.The results showed that the survival rate of M.liliflora was significantly impacted by different grafting methods.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 times.During the dormancy of M.liliflora,in September,the survival rate was the highest(96.5%),followed by October(91.3%) 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 scion,81.6% in shoot side grafting with terminal bud of shoot as a scion,and 87.1% in cleft grafting with central full bud as a scion.Weak buds on the lower part of shoots were not suitable to be used as grafts.Generally,grafted M.liliflora started to blossom 3 years later.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.
In order to seek high-efficient, practical and simple grafting methods, to establish scientific and effective technology system of raising seedlings by grafting, and to achieve the intensive cultivation of Magnolia liliflora Desr., The grafting techniques of M. liliflora were studied through experiments , including cleft grafting, tongue grafting, single-bud side grafting, shoot side grafting, and bud slice side grafting. The results showed that the survival rate of M. liiliflora was significantly impacted by different grafting methods. 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 times. Playing the dormancy of M.liliflora, in September, the survival rate was the highest (96.5%), followed by October ( 91. 3%) 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 scion, 81.6% in shoot side grafting with terminal bud of shoot as a scion, and 87.1% in cleft grafting with central full bud as a scion.Weak buds on the lower part of shoots were not suitable to be used as grafts.Generally, grafted M.liliflora started to blossom 3 years later.
