摘要
杉木是我国人工林面积最大的造林树种,在我国林业产业中占有重要地位.随着市场对杉木大径材需求不断增加,有关杉木大径材高效培育的研究成为热点,取得了较多研究成果.文中分别从遗传控制、立地控制、密度控制等方面综述杉木大径材培育的研究进展,探讨杉木大径材培育的技术体系,指出目前大径材培育研究中存在的问题,并提出加强杉木大径材培育品种筛选、进行高世代良种杉木大径材成材机理长期定位观测、加强杉木大径材定向培育技术的组装配套研究及编制适合大径材培育使用的长轮伐期杉木地位指数表等建议,以为杉木大径材培育提供科学依据.
Abstract
Chinese fir is a tree species that is used for afforestation,constituting the largest planted area in China and occupying an important position in China's forestry industry.With the increasing market demand for large-diameter timber of Chinese fir,the research on high-efficiency cultivation of large-diameter timber trees of Chinese fir has become a hotspot,consulting in a large number of results.This paper reviews the research progress in the cultivation of large-diameter Chinese fir trees from the aspects of genetic control,site control and density control,discusses the technical system for the cultivation,and identifies the existing problems in the current research in this regard.Suggestions are put forward to provide science evidences for the cultivation of large-diameter Chinese fir tree,i.e.,strengthening the selection of varieties for large-diameter tree cultivation,conducting long-term positioning observation of the formation mechanism of high-generation and well-bred large-diameter trees,enhancing the research on the assembling of the cultivation technology,and compiling the site index table of large-diameter trees in long-rotation period.
