华山松(Pinus armandi Franch),生长快,适应性强,材质优良,是贵州中西部高寒地区重要用材树种。为解决贵州华山松造林用种需要,1978年就开始在华山松自然分布区的威宁建立华山松良种繁育中心。由于我省开展林木良种繁育研究工作历史较短,近几年来各地虽选出了部分华山松优树,但远远解决不了建立大型无性系种子园所需的物质基础。因此,在开展对初选优树复查的同时,探讨比较合理的方法,从现有华山松资源中选出大量的优树,解决建园的迫切需要,这
Pine (Pinus armandi Franch), grow fast, adaptability, good material, is an important wood species in the alpine region of central and western Guizhou. In order to solve the need of afforestation of Huashan pine in Guizhou, Huashan pine elite breeding center was established in Weining, a natural distribution area of Huashan pine in 1978. Because of the short history of the research on tree seed breeding in our province, some parts of Pinus armandii have been selected in recent years, but the material basis for establishing large-scale clonal seed orchard can not be solved far. Therefore, while carrying out the review on the primaries, it is necessary to explore a more reasonable method to select a large number of excellent trees from the existing resources and to solve the urgent need of building gardens.
