摘　　要：兴安落叶松适生于大兴安岭与小兴安岭山脉,是东北地区的乡土树种。兴安落叶松第二代种子园,是在乌兰坝林场国家落叶松良种基地兴安落叶松子代测定林中,通过5株大树法筛选出的28个优良无性系作为建园材料,于2020年在内蒙古自治区赤峰市巴林左旗乌兰坝林场营建的种子园,面积1 hm^(2)。研究从建园材料选择、营建过程、抚育管理和树形管理等方面分析兴安落叶松第二代种子园营建的关键技术,以期为我国东北地区兴安落叶松第二代种子园建设提供参考。Larix gmelinii is native to the Greater and Lesser Khingan Mountains and is an indigenous tree species in Northeast China.The second-generation seed orchard of Larix gmelinii was established in the Ulanba Forest Farm,a national Larix gmelinii breeding base,in 2020.This orchard covers an area of 1 hectare and was built using 28 superior clones selected through the five-tree method from progeny test forests.This paper analyzes the key techniques for establishing the second-generation Larix gmelinii seed orchard,covering aspects such as the selection of orchard materials,establishment process,tending management,and tree form management,with the aim of providing a reference for the construction of second-generation Larix gmelinii seed orchards in Northeast China.
