樟子松(pinus sylvestris L.var.mongolica litv.)是我国东北地区的主要速生用材树种,材质良好,用途广泛。1962年引入我区育苗,1964年在榆林红石峡沙地造林,现已成林,长势良好。平均树高5.5米,平均胸径10.5厘米;最大树高6.4米,胸径14.0厘米,成为我区深受群众欢迎的用材树种。为了探索樟子松沙地造林技术,促进成活生长,1979年在红石峡沙地进行不同造林季节、配置方式、菌根造林、幼林管理等技术措施实验。现将结果初报于后。
Pinus sylvestris L.var.mongolica litv. Is the main species of fast-growing timber in northeastern China, with good materials and wide range of uses. Introduced in our district nursery in 1962, afforestation in Hongshi Gorge in Yulin in 1964, has now become a forest, growing well. The average height of 5.5 meters, the average diameter of 10.5 cm at breast height; the maximum height of 6.4 meters, diameter 14.0 cm, become my area popular timber species. In order to explore the afforestation technology of Pinus sylvestris var. Mongolica and to promote its survival and growth, experiment on different afforestation season, configuration, afforestation and management of young forest were conducted in Hongshi Gully Sandy Land in 1979. The results will be reported later.
