新平县杉木引种造林研究

摘要

介绍杉木引种造林基本条件、技术路线和依据,从气候指标、土壤特性、植被特性、杉木生长发育规律、杉木自然分布带等方面进行相关性分析和论证,并对新平县杉木生产引种的成活率、保存率、成材率、生长量等进行分析,认为与杉木自然分布区和主要栽培区一样,新平县在杉木人工造林方面不存在技术问题,且引种造林生长量达到国家杉木速生丰产林标准.%China fir introduction and plantation conditions, technical route, and the basis were introduced , from aspects of climate, soil properties, vegetation characteristics, fir growth pattern and fir natural distribution, the correlation analysis and demonstration have been conducted in this paper, meanwhile, survival rate, leftover rate, lumber recover rate, growth rate of China fir introduction and plantation in Xinping also been analyzed, thereby, we believed that the fir natural distribution area and the main cultivation area were correlation, there were not technical problems in China fir introduction and plantation in Xinping County, moreover, the growth volume of introduced china fir in Xinping County has reached to State criteria of fast growing forest.
