人工林资源是森林资源的重要组成部分。我国人工林总体质量不高,普遍存在着生长量低、保存率低以及生产力低下等问题。文中在对人工林生产力研究的历史背景进行回顾的基础上,概述立地条件、初植密度、间伐措施、林地清理、连栽代数、施肥等方面对人工林生产力产生的影响,提出了促进我国人工林生产力维持关键技术体系研究的建议,即加强人工林生产力长期性、系统性、多目的性的研究。
Plantation resources are an important part of forest resources. The overall quality of plantation in our country is not high, with the problems of low growth rate, low preservation rate and low productivity. Based on the review of the historical background of plantation productivity research, this paper summarizes the impact of site conditions, planting density, thinning measures, woodland cleaning, even planting algebra, fertilization on the productivity of plantations, Forest productivity Maintain the key technology system research proposal, that is to strengthen the productivity of plantation long-term, systematic, multi-purpose research.
