在吉林省日本落叶松比其它落叶松生长要快得多,但目前基本上都是用种子繁殖后代,这些种子来源于自然授粉所得杂交种,因此,繁殖的苗木好坏相差悬殊,给培养优良种苗带来一定困难。为了保持优良个体的特性,利用扦插繁殖后代,是一种比较理想的方法,尤其对种子园的建立,具有一定的实用价值,在生产上也是一种可取的方法。我们于1983～1986年对日本落叶松进行了嫩枝扦插试验,现将结果报道如下。 Larix japonica is much faster than other larches in Jilin Province. At present, however, most of the seeds are used to breed offspring. The seeds are derived from the cross pollination of natural pollination. Therefore, the breeding seedlings vary greatly in quality, Seedlings bring some difficulties. In order to maintain the characteristics of excellent individuals, the use of cuttings to breed progeny is an ideal method, especially for the establishment of seed orchard, has a certain practical value, is also a desirable method of production. We conducted a shoot cutting test of Japanese larch from 1983 to 1986 and the results are reported below.
