华北落叶松历年来用种子繁殖,用扦插方法生根十分困难。近年来,河北平顶山林场曹瑞廷等用华北落叶松(兼有长白落叶松、日本落叶松)2—24年生的母树,当年生枝条作扦插试验,初获成功。试验表明: 1.不同品种的落叶松均能扦插繁殖,但以华北落叶松生根率最高,10年生以下的母树剪取的当年生枝条生根率达79—98.3％。
Larix principis-rupprechtii seed propagation over the years, with cutting method is very difficult to root. In recent years, Ping Rui Ting, Pingdingshan Hebei and other plants with Larix principis-rupprechia (both Changbai larch, Japanese larch) 2-24 years old trees, annual branches for cutting test, the initial success. The results showed that: 1. Different species of larch could cuttage propagation, but the rooting rate of Larix principis-rupprechtii was the highest, and the rooting rate of current-born branches cut from mother tree below 10 years old reached 79-98.3%.
