摘　　要：通过对引进落叶松杂种苗进行栽培试验,调查树高、胸径及年生长量等,分析树高和胸径早期生长表现,结果表明:胸径连年生长量从栽植第8年开始增长显著,树高连年生长量在栽植第9年开始增长显著;初选出宜于山西省中高山地区栽培的落叶松家系3个,分别为日永8、日永85×长13和日永7×华马7。Through the cultivation experiment of introduced Larix gmelinii hybrid seedlings,tree height,DBH annual growth were investigated; tree height and DBH annual-growth-performance were analyzed. Result shows that the annual growth of DBH increase significantly at eighth years,the annual growth of tree height increase significantly at ninth year. The three Larix gmelinii families which are suitable for cultivation in the middle and high mountain areas of Shanxi Province were selected,namely,Larix gmelinii ‘Riyong 8＇,Larix gmelinii ‘Riyong 85 × Chang 13＇and Larix gmelinii‘Riyong 7 ×Huama 7＇.
