红皮云杉优良家系选择及不同栽培模式的研究

摘要

Korean spruce progeny forest(20 Families and 1 control stand) of 12-year-old were investigated.The results showed that the difference between tree height and DBH was significant.Three superior families were selected, included two best superior families.Three kinds stand of different density cultivation patterns were designed and analyzed.The results showed that the cultivation model of planting spacing 1.5 × 2m was better.%<中作者单位二>=黑龙江省林业科学研究所对12年生红皮云杉子代林(20个家系、1个对照)生长进行调查分析,结果表明红皮云杉各家系间(树高和胸径)差异及显著,初步选出3个表现较好的优良家系,其中最优良家系2个;对设计3种密度栽培模式进行调查分析,结果表明1.5×2m栽培模式生长表现较好.
