华北落叶松历来采用种子繁殖,用扦插方法生根十分困难。近三年来,我们用华北落叶松(兼有长白、日本落叶松)2—42年生的母树当年生枝条作了扦插试验,初获成功。现将试验方法和结果介绍如下:一、试验方法和内容1、试验材料:插条有硬枝、嫩枝;枝龄为2,3,6,10,13,15,22,23,42年生母树上的当年生枝和部分一年生枝。2插壤:采用森林腐殖质土、腐殖土掺牛马粪、松林地菌根土、粗骨土、粗砂、粗砂掺10％菌根土、粗砂掺10％羊粪。

Larix principis-rupprechtii has been used for seed multiplication, with cutting method is very difficult to root. The past three years, we use the Larix principis-rupprechtiu (both Changbai, Japanese larch) 2 - 42-year-old tree branches were made when the cuttings experiment, initially successful. Now the test methods and results are described below: First, the test methods and content 1, the test materials: cuttings hard branches, shoots; branches of 2, 3, 6, 10, 13, 15, 22, 23, 42 years The current year branches and some annual branches on the mother tree. 2 Loose soil: the use of forest humus soil, humus soil mixed cattle horse manure, pine woodland root soil, coarse bone soil, coarse sand, coarse sand mixed with 10% mycorrhizal grit mixed with 10% sheep manure.
