日本落叶松和华北落叶松的扦插繁殖已有报道(林业科技通讯 1979),长白落叶松的扦插繁殖在沈阳应用生态研究所也已有多年经验,唯兴安落叶松的扦插繁殖至今尚未有成功的报道。1987年大兴安岭北部特大森林火灾后,人工更新任务艰巨,当时种子又奇缺,人们不但希望通过兴安落叶松的扦插繁殖解决种品不足问题,也希望以此为良种繁育提供手段,利用无性繁殖体早期生长上的优势来解决尽快恢复森林的问题。我们从1988年引进全光自动间歇喷雾装置,开始在大兴安岭北部火烧区的图强林业局进行扦插试验,1990年春已将育出的3000
Cutting propagation of Larix kaempferi and Larix principis-rupprechtii (Forestry Science and Technology Newsletter 1979) has been reported. Cutting propagation of Larix olgensis has also had many years of experience in Shenyang Institute of Applied Ecology. The cutting propagation of Larix gmelinii has so far not been successful Reported. In 1987, after the large forest fire in the northern part of the Greater Hinggan Mountains, the task of artificial regeneration was arduous. At that time, the seeds were scarce again. People not only hoped to solve the problem of seed shortage through cutting propagation of Larix gmelinii, but also provided the means for the breeding of fine seeds. The advantages of early growth to solve the problem of forest restoration as soon as possible. We introduced from 1988 all-optical automatic intermittent spray device, began to fire in the northern part of Daxinganling Tuqiang Bureau of Forestry conducted cutting tests, the spring of 1990 will have raised 3000
