嫩枝劈接是杜鹃嫁接中采用较广的一种方法。然而由于杜鹃的枝条纤细,创口愈合较慢,所以嫁接成活率不一定理想。下面介绍一下我们在这方面操作中获得的一些体会。 1.从枝条的木质化程度来看,接穗最好比砧木老一些,这样可以减少接穗对水份、养份的消耗,有利于成活。 2.嫁接接穗的枝条,最好选择主枝的顶稍徒长枝或由基部萌蘖而新生成的枝条,这些枝条的营养 Twig splitting is a widely used method of rhododendron grafting. However, due to the rhododendron slender branches, wound healing is slow, so the survival rate of grafting is not necessarily ideal. Here are some of the experiences we have gained in this area of ​​operation. 1. From the perspective of the degree of lignification of the branches, the scion is preferably older than the rootstock, which can reduce the scion of water, nutrients consumption, is conducive to survival. 2. Grafting scion branches, it is best to choose the main branch of the top long branch or sprout from the base of the newly formed branches, the nutrition of these branches
