本文以长白落叶松扦插及扦插苗移栽试验为基础,对大量的影响因素进行了系统研究。确定了母树年龄、基质类型和树冠部位是扦插生根的主要影响因素。从幼树的树冠中部和上部采取嫩枝扦插在细河砂组成的基层上生根率最高。试验还表明长白落叶松的不同种源及同一小北湖种源的不同家系扦插生根率差异显著。长白落叶松扦插苗越冬后移栽成活率达到91.1％。
In this paper, the Larix olgensis cuttings and cutting seedlings transplanting test based on a large number of influencing factors were systematically studied. The main factors affecting the rooting of cuttings were identified as the age of the female tree, the type of the stroma and the position of the crown. From the sapling crown and the upper part of the young shoots taken in the fine sand composition of grass roots on the highest rooting rate. The experiment also showed that the different provenances of Changbai Larch and the rooting rate of cuttings of different families in the same small North Lake provenance differed significantly. Larix olgensis cuttings after transplanting survival rate of 91.1%.
