摘要
黑龙江省伊春林区,正在从传统林业向现代林业转变,林业工作的重点已从木材生产向生态建设为主方向发展。林区的天然次生林已受到保护,而大力发展速生丰产林、原料林已成为新的发展方向,树木引种驯化在林区新的发展形势下显得尤为重要。它不但可以为林区发展商品林提供新的选择,而且对丰富林区的树种组成、开展遗传育种等林学工作,提供了新的种质材料。日本杂交落叶松(Larix kaempferi X Larix gmelinii日X兴)生长快、抗性强、耐干旱瘠薄、耐高寒,引种已获成功。本文实录了日本杂交落叶松引种驯化情况。
It is transfering from traditional forestry to modern forestry Yichun state-owned forest areas.Forestry focus has transfered from timber production to ecological construction.Forestry.The majority of the natural secondary forest has been protected,and developing of fast growing trees and raw material forest become the new development direction.Introduction and domestication of the trees is very important under the new development situation.It can provide new options for the development of commercial forest and new germplasm materials for rich species composition and developing genetics and breeding.Larix kaempferi X Larix gmelinii has characteristics of growing fast,strong resistance,drought-resistant and cold-resistant.Its introduction have been successful.Introduction and domestication of the Larix kaempferi X Larix gmelinii was recorded.
