湿地松生长快、干形直、抗松毛虫,是当前极需发展的重要树种之一,但种源不足。为此,广东省林业科学研究所在1963—1964年,选用湿地松优势木作接穗,以马尾松作砧木,按髓心接触形成法进行嫁接试验。结果表明,湿地松与马尾松嫁接的亲和力相当强,3—9月份嫁接都能成活,特别是7—8月份,采用瓶接的成活率达61.5—89.5%。嫁接后,接穗生长迅速,例如,1964年3月26日用7年生湿地松接穗 Slash growth fast, dry-shaped straight, anti-caterpillar, is currently very much needed to develop one of the species, but the lack of provenance. To this end, the Guangdong Provincial Forestry Science Institute in 1963-1964, the use of dominant species of Slash Pine as a scion, Masson pine as the rootstock, according to the medullary contact formation grafting test. The results showed that the affinity of Pinus elliottii and Grafted Pinus massoniana was very high, and the grafting could survive from March to September. The survival rate of bottle join from July to August was 61.5-89.5%. After grafting, the scion grows rapidly, for example, on March 26, 1964 with a 7 year old spike
