摘　　要：为选择赤松优良种源,在章古台地区开展11个种源的赤松播种育苗试验。结果表明:不同种源间子代苗木表现存在着较为明显的差异,其中,章古台三家子种源表现良好;吉林敬信种源1年生、2年生苗木高生长和2年生地径生长都表现都较好,1年生苗封顶率达到了88%,为各种源之最,能安全越冬,为当地适宜种源,南方种源对北方地区环境适应能力差,露天播种育苗不能安全越冬。In order to select the excellent provenance of Pinus densiflora,the Pinus densiflora seedling experiment of eleven provenance was carried out in Zhanggutai area.The results showed that there were obvious differences in the performance of offspring seedlings between different provenance,among which Zhanggutai Sanjiazi provenance performed well.The height growth of 1-year and 2-year seedling and ground diameter growth of 2-year seedling of Jilin Jingxin provenance all performed well,and the capping rate of 1-year seedling reached 88%which was the best of all provenances and the local suitable provenance overwintering safely.The southern provenance has poor adaptability to the northern environment,and the open sowing and seedling cannot safely survive the winter.
