我省盆周山地海拔1200—2000m,森林植被稀疏,不少荒山秃岭.现有植被除在远山交通不便的地方外,上部多为经济价值低的次生林.由于气候寒冷,水份较高,种树选择受到很大限制,可供人工栽培利用的树种较少,是我省加速荒山绿化进程中的一大难题.引种秃杉旨在丰富盆周山地造林树种,为开发盆周经济创造条件.秃杉(Taiwania flousiana Gaussen),速生高产.据了解在云南54年生人工秃杉林,每公顷蓄积量1729,945m~3,(年均生长量2.13m~3/亩),单株材积2m~3,比著名的
In the province, the basin and mountain are 1200-2000m above sea level, with sparse forest vegetation and many bald patches of barren hills. The existing vegetation is mainly the secondary forest with low economic value, except for the traffic inconvenience in the distant mountains. Due to the cold climate and high water content , Tree selection is subject to a lot of restrictions for artificial cultivation and utilization of fewer species, is our province to speed up the barren hills and greening process is a major challenge. Introduction of bald’s fir is intended to enrich afforestation trees in the basin, for the development of basin economy Conditions Taiwania flousiana Gaussen (Taiwania flousiana Gaussen), a fast-growing and high-yielding plantation, is found in the 54-year-old Taiwanese tallow tree in Yunnan Province with an accumulated volume of 1,729,945m 3 per hectare (average annual growth rate of 2.13m 3 / mu) ~ 3, better than famous
