辐射松原产于美国加利福利亚、耐干旱、贫瘠 ,生长较快 ,材质好 ,先后被新西兰、澳大利亚、智利等几十个国家引进 ,表现良好。我省曾于 80年代在盆地内部引种失败。1 989年 ,我省阿坝州开始在干旱河谷地区进行引种试验 ,取得阶段性成果。1 997年 ,四川省林业厅批准《干旱地区辐射松引种造林试验》课题 ,进行进一步的试验研究。课题组进行了育苗、造林的对比试验 ,基本掌握了辐射松育苗、造林和引种驯化技术 ,特别是扦插育苗的成功 ,为该树种的大面积推广 ,提供了物质、技术保证
Radiata pine originated in the United States, California, drought-resistant, barren, rapid growth, good material, has been New Zealand, Australia, Chile and other dozens of countries to introduce good performance. In the 1980s, our province failed to introduce seeds in the basin. In 1989, Aba Prefecture in our province started the introduction experiment in the dry valley area and achieved initial results. In 1997, the Sichuan Provincial Forestry Department approved the project of “Introduction and Afforestation Experiment of Pinus radiatus in Arid Areas” to carry out further experimental research. The research group carried out comparative experiments on nursery and afforestation and basically grasped the success of radiation pine seedling, afforestation and introduction and acclimation techniques, especially cuttage nursery, and provided material and technical assurance for the large-scale popularization of the tree species
