摘　　要：应用树干解析和选择超级苗营造对比试验林的方法,对红皮云杉的生长变异及早期选择技术进行研究。结果表明,红皮云杉个体各生长性状的变异规律是幼龄阶段变异较大,随年龄的增长,变异逐渐减小;树高、胸径、材积变异趋于平缓的年龄分别为9 a生1、5 a生和9 a生。用9 a生的胸径生长预测33a生的材积生长是适宜的。对红皮云杉出圃苗采取平均苗高+2倍标准差的标准进行选择,通过幼林阶段的观察,证实苗期选择是有效的。Growth variation of Picea koraiensis and early selection was studied by stem analysis and establishing a comparative forest using super-seedlings.The results showed that the variation of individual growth traits was significant in young stage,and decreased the variability with age of growth;the variations were not obvious in its tree height,diameter at breast height,volume at ages of 9,15 and 9 years,Separately.It is appropriate to forecast volume growth of 33 yr-old tree with diameter growth at breast heig...
