摘要
为了提高宜昌山区 (海拔 1 0 0 0~ 2 0 0 0m)针叶树新造林分生产力 ,为本市引种驯化筛选出最适宜的工业用材树种 ,以达到工业用材林定向、速生、丰产、优质、稳定和高效的目标。我们于 1 980年开展了欧洲云杉、日本冷杉、欧洲赤松等几种工业用材针叶树种引种选择研究。研究结果表明 :欧洲云杉、日本冷杉、欧洲赤松的生长量分别比对照油松大 1 6%~ 2 8% ,1 9% ,2 2 8%。
In order to raise productivity of newly-afforestated conifer stand in mountain area of Yichang (1 000~2 000 m above sea level) so as to screen out most suitable industrial timber species for introduction and domestication in this city and aim at goals of orientation, fast-growing and high-yield, excellent quality, stablization and high-effectiveness. We developed a study on introduction and selection for several kinds of industrial timber conifer species such as European spruce, Japanese fir and Scotch pine. The result shows that increment for European spruce, Japanese fir and Scotch pine is 16%~28%, 19% and 22.8% higher than that of contrast Chinese pine in order.
