摘要
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。
Korean spruce progeny forest （20 Families and 1 control stand） of 12 -year- old were investigated. The re-suits showed that the difference between tree height and DBH was significant. Three superior families were selected, in-cluded 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 x 2m was better.
