含笑(Michalia figo(Lour.)Spreng)是我国南方露地栽培的常绿花木,为名贵的观赏树种。在我国南方各地繁殖含笑,通常多用高压和靠接繁殖,也有用播插繁殖的,但存在成活率低、生长慢、开花迟、效益差等问题。我们带着如何加快繁殖速度和降低生产成本等问题,于1985年用大枝径切扦插培育自根苗进行试验研究。两年来培育出的含笑自根苗,在大田或盆栽长势喜人,枝叶繁茂,树形幽雅。用此法培育含笑自根苗是扩大繁殖系数,加快繁殖速度,降低生产成本的一个重要途径。
Michalia figo (Lour.) Spreng is an evergreen tree planted in the open fields of southern China. It is a valuable ornamental tree species. In South China breeding reproductive smile, usually with high pressure and docking propagation, but also useful sow propagation, but there are low survival rate, slow growth, late flowering, poor efficiency and other issues. With the problems of how to speed up reproduction and reduce production cost, we carried out experimental researches on the self-rooted seedlings with large branch cuttings in 1985. Two years to cultivate self-rooted smiley, growing in the field or potted plants, lush foliage, elegant tree. This method to cultivate self-rooted larvae is an important way to expand the breeding coefficient, speed up breeding and reduce production costs.
