大径材是我国极为紧缺的战略物质,秃杉(Taiwania flousiana)是培育大径材的理想珍贵树种,通过5年的试验研究,形成了从立地条件选择、壮苗培育、造林、幼林抚育管理和密度控制等配套的秃杉人工林大径材培育技术,提高了林木生长量,30年可培育出径级达40cm以上的大径材,超过国家行业标准LY/T 1951-2011《秃杉速生丰产林》中大径级用材林的生长量指标,比原标准缩短培育周期10年以上,在我国珍贵树种大径材战略储备基地的建设中具有广阔的应用前景。
Large-diameter timber is an extremely scarce strategic material in our country. Taiwania flousiana is an ideal and valuable species for cultivating large-diameter timber. After five years of experimental research, it has formed a series of research projects ranging from site selection, seedling cultivation, afforestation, And density control and other supporting Taiwania flousiana plantation large diameter timber cultivation techniques to improve the growth of trees, 30 years can grow diameter of 40cm or more large diameter timber, more than the national industry standard LY / T 1951-2011 “Taiwania flousiana Fast-growing and high-yielding forest ”medium-large-diameter timber growth indicators, shorter than the original standard incubation period of 10 years or more, in our precious tree species large diameter timber reserve strategic base has broad application prospects.
