用松针叶束做接穗,进行嫁接繁殖,这是松类树种无性繁殖的一项新技术。中国林科院亚林所陈孝英等(1987)首先在湿地松、马尾松、火炬松获得成功,其后北京林业大学沈熙环等(1990)又在油松取得成功。这种嫁接繁殖技术突破了松类无性繁殖开辟了一条新路。黑松属硬松类,扦插繁殖很难克服母树年龄效应的影响。据烟台市林科所报道,用 Use pine needles do scion, graft and reproduction, which is a new technology of asexual reproduction of pine trees. Chen Hsiao-ying et al. (1987) from Yulin, China Academy of Forestry, first succeeded in Pinus tabulaeformis, Pinus massoniana and Pinus taeda. Later, Shen Xihuan et al. (1990) from Beijing Forestry University again succeeded in Pinus tabulaeformis. This grafting and propagation technology broke through the pine asexuality has opened up a new road. Cedar hardwoods, cutting propagation is difficult to overcome the effects of age of the parent tree. According to Linke Yantai City, reported
