五针松是名贵的观赏树木,也是盆景常用的上好材料。过去五针松常用腹接或靠接法繁殖,但这种方法由于砧木年龄小,嫁接后生长、成形缓慢。近年来,我们用马尾松或黑松株龄较大植株作砧木,选五针松带有顶芽的小枝作接穗,在砧木枝条适当部位,用高接换头方式进行嫁接。这种方法繁殖容易,管理方便,而且可以在一株砧木上接上多个 Pine needles are expensive ornamental trees, but also the bonsai commonly used on the good material. In the past, five acupuncture points were usually aborted by abdomen or by abutment method, but due to the small age of rootstock and the growth after grafting, this method was slow to form.

The appropriate branches of the rootstocks are grafted by the method of high exchange heads. This method is easy to reproduce, easy to manage, and can be more than one rootstock
