扦插是植物无性繁殖的手段之一。扦插繁殖具有保持母本优良性状、加快繁殖系数,提早开花结实等优点。因此,在遗传育种、良种繁育、引种驯化和园林生产等方面广为应用。据报道,松属的各种,插穗生根困难。在国外有些学者已把研究的重点转移到松树扦插繁殖方面来,但到目前为止尚未完全过关。同时也有些学者已把研究工作深入到生根生理方面,在揭示生根机制上都做出了不少的工作。在国内,目前主要还停留在解决某些树种的扦插方法方面,开展了一些树种的扦插试验,虽已取得了较明显的效果,但在试验手段上与国外相比差距较大。

Cutting is one of the means of plant asexual reproduction. Cutting propagation has the advantage of maintaining the excellent traits of female parent, speeding up the propagation coefficient, early flowering and fruiting. Therefore, it is widely used in genetic breeding, seed breeding, introduction and domestication and garden production. It is reported that all kinds of pine, cuttings rooting difficulties. Some scholars abroad have shifted their research focus to the cutting propagation of pine trees, but so far they have not yet completed their customs clearance. At the same time, some scholars have also made deep research on rooting physiology and have done a lot of work in revealing the rooting mechanism. At home, at present, mainly in the settlement of some species of cutting methods, carried out some species of cutting test, although has made a more significant effect, but in terms of experimental methods and abroad, a larger gap.
