辐射松(PinusradiataD.Don)原产于加利弗尼亚海岸,被引种到世界各地,现在是南半球主要的人工林造林树种。1990年以来辐射松被引种到长江上游四川省阿坝州的干旱河谷地区,幼树的成活和早期生长表现良好。本文的主要内容包括:辐射松在原产地和引种地的生长情况,种源和遗传上的差异,环境限制因子和辐射松的气候生境,病虫害,引种不成功的经验教训以及辐射松在生态恢复中的应用。文中还简述了辐射松在阿坝干旱河谷地区的早期生长情况,列举了在长江上游干旱河谷地区引种辐射松可能遇到的问题以及所需开展的研究。图4表5参90。
Originally native to the California coast, Pinus radiata D.Don is introduced throughout the world and is now the dominant plantation tree species in the southern hemisphere. Since 1990, Pinus radiata was introduced into the arid valley in Aba Prefecture, Sichuan Province, in the upper reaches of the Yangtze River. The survival and early growth of young saplings have been well performed. The main contents of this article include: the growth of Pinus tabulaeformis in its place of origin and introduction, provenances and genetic differences, environmental constraints and climatic habitats, pests and diseases of Pinus radiata, unsuccessful introductory lessons and the ecological restoration of Pinus radiata In the application. The article also briefly described the early growth of Pinus radiata in the dry valley of Aba, and cited some problems that may be encountered in the introduction of Pinus tabulaeformis in the upper reaches of the Yangtze River.
