杜鹃花(Rhododendron)是世界名花,具有很高的观赏价值,对于杜鹃花的扦插繁殖已广为园艺工作者所采用,但所利用的多属栽培品种;而对于种类繁多、观赏价值极高的高山常绿杜鹃及落叶野生类杜鹃的扦插繁殖,在国内做得很少。因杜鹃花的种子极小,用种子繁殖难度大,且幼苗期生长缓慢,以致不能快速培成大批苗子。采用扦插无性繁殖法。将有利于野生杜鹃的开发利用。

Due to the tiny azalea seeds, seed multiplication difficult, and the slow growth of seedlings, resulting in rapid cultivation into a large number of seedlings. Using cutting propagation asexual. Will be conducive to the development and utilization of wild rhododendron.
