日本落叶松(L·Kaempferi Sarge)在我省比其它落叶松生长的快,抗性也强。为了保持优良个体的特性,利用无性繁殖方法繁殖优树后代,省林研所育种室于84—85年对日本落叶松进行了嫩枝扦插试验,初获成功。1984—1985两年,分别从7、8年生树上采取当年生半木质化枝条,采取时间为7月8—11日之间,插条长度为12—15厘米。当天采条当天处理,抹去下部1/3的叶子,84年每一处 Japanese larch (L. Kaempferi Sarge) grows faster and more resistant than other larches in our province. In order to maintain the characteristics of excellent individuals, the best offspring were propagated by means of asexual reproduction method. The provincial Forestry Research Institute breeding branch successfully conducted the shoot cutting experiment on Japanese larch in 84-85 years. From 1984 to 1985, the half-lignified branches of the year were taken from the annual trees of 8-8 years respectively. The time taken was July 8-11, and the length of cuttings was 12-15 cm. The same day mining day processing, erasing the lower 1/3 of the leaves, 84 every one
