摘　　要：于2016—2019年在内蒙古林科院树木园对10种引种驯化云杉属植物的物候进行了初步观测和分析,以期为保存现有品种和继续引种驯化提供理论基础。结果表明:10种云杉属植物进入各个物候发生时间随年度不同出现波动,但物候发生顺序不变,基本在4月上旬进入顶芽萌动始期,4月中下旬进入展叶期,4月底5月初进入始花期,7月中下旬进入顶芽封顶始期,10月上中旬种子进入成熟始期;10种云杉属植物进入各个物候期发生时间存在差异,进入各个物候发生时间相对较早的是青海云杉、粗枝云杉,而相对较晚是北美蓝云杉。In order to provide theoretical basis for preserving the available Picea species and introducing other varieties of Picea continuously,the phenological characteristics of 10 Picea species were initially observed and analyzed in Arboretum of Inner Mongolia Academy of Forestry from 2016 to 2019.The results showed that the phenological occurrence time of 10 Picea species fluctuated in different years,but the phenological occurrence sequence of 10 Picea species did not change,with a sequence of the leaf-expansion period in beginning of April,leaf-expansion period in middle to late April,the early flowering phase at the end of April and beginning of May,the binding of terminal bud in middle to late July,and seed maturation period from early to middle of October.The phenological occurrence time of 10 Picea species in different phenological periods was different.The phenological occurrence time in each phenological period was relatively early for Picea crassifolia and P.asperata,and relatively late for P.pungens.
