白兰花繁殖方法一般有两种:即压条和嫁接。嫁接法过去常用靠接,仅此法操作不便,生长缓慢,接穗利用不经济,大量繁殖受到接穗局限。故若改用切接法,成活率可达90％以上,生长较快,长势很好。这对目前加速发展花卉生产,提高经济效益大有好处。其具体方法如下:一、切接砧木一般选用二年生的同种异属的紫玉兰,一年生的若有小指粗细的也可用。切接接穗即采用发育良好且无病虫害的白兰花二年生枝条。
White orchid breeding methods generally have two: the pressure and grafting. Grafting method used to rely on the past, only this method of operation inconvenience, slow growth, scion use of uneconomical, large-scale propagation of scion limitations. Therefore, if the switch to cut access method, the survival rate of up to 90% or more, grow faster, growing well. This is of great benefit to accelerating the development of flower production and improving economic efficiency. The specific methods are as follows: First, cut the rootstocks generally use biennials of the same genus Magnolia, the annual pinky finger thickness is also available. Cut the scion that is well-developed and pest free perennial branches of white orchids.
