本项研究是根据全国毛白杨科研协作组的统一安排,采用常规的调查方法,对甘肃陇东、陇南地区18个县(市)的毛白杨进行了系统的调查研究,基本摸清了毛白杨的资源、分布、习性及生长规律,并发现了毛白杨新类型—憨白杨,保存收集基因500个品系,建立种源试验基地20公顷,完成了毛白杨种源试验科研第一阶段基因资源的保存和收集任务,为进一步保护利用和积极发展这一乡土树种,从理论上提供了依据,从物质上进行了准备.
This study is based on the unified arrangement of the National Cooperative Research Group of Populus tomentosa, using conventional methods to investigate the Populus tomentosa in 18 counties (cities) in Longdong and Longnan of Gansu, The distribution and habits of the Populus tomentosa and its growth pattern were also studied. A new Populus tomentosa type was discovered, 500 lines of which were collected and collected, and 20 hectares of provenance base were established. The genetic resources of Populus tomentosa Preservation and collection of tasks, in order to further protect the use and development of this native tree species, provided the basis in theory, materially prepared.
