杉树-红椿混交种植技术

Taxodiaceae Warming and Toona ciliata Roem. Mixed Planting Technique

  • 摘要: 我国杉木人工纯林面积位列人工乔木林之首,有着重要的生态防护功能和较广泛的经济用途,对生态环境保护和社会经济发展有着极为重要的影响。长期以来,我国杉木纯林连作的培育模式造成了地力退化、森林质量下降、病虫害蔓延等问题,浪费了宝贵的林地资源,对区域生态平衡、物种多样性和社会经济发展都造成了较大影响。文章从工作实际出发,结合国内杉木混交林研究成果,提出了杉木混交红椿的培育措施,旨在通过针阔树种混交提高林地资源利用效率、改善林分结构,解决杉木纯林长期连作存在的问题,以期为林业科技工作者和广大林农提供有益借鉴。

     

    Abstract: Chinese Taxodiaceae Warming artificial pure forest area ranks the first artificial tree forest, has important ecological protection function and wider economic use, has a very important impact on ecological environment protection and social and economic development. For a long time, the continuous cultivation mode of Taxodiaceae Warming artificial pure forest has caused soil fertility degradation, forest quality decline, the spread of pests and diseases, wasted valuable forest resources, and had a great impact on regional ecological balance, species diversity and social and economic development. Based on the actual work and the research results of Chinese Taxodiaceae Warming artificial mixed forest, this paper put forward the cultivation measures of Taxodiaceae Warming artificial mixed forest, aiming at improving the utilization efficiency of forest resources, improving the stand structure and solving the problems of long-term continuous cropping of Chinese Taxodiaceae Warming artificial pure forest through the mix of coniferous and broad tree species, in order to provide useful reference for the workers of forestry science and technology and the majority of forest farmers.
