摘要
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％。
On the basis of experiments of the cuttage propagation and cuttings transplanting of Larix olgensis, a lot of factors which affect the cuttings have been systematically studied. The main effective factors which affect the rooting are the seed-tree age, the medium type and the position in the crown. The optimal combination for rooting is the young seed-tree, fine sand medium and the cuttings fram middle of the crown. It also indicates that there are significant differences among the different provenances and the different families within the Xiaobeihu provenance in rooting rate. The survival rate of the cuttings of Larix olgensis transplanted got to 91.1％ after winter.
