西伯利亚红松造林效果初探

A preliminary studies on the afforestation of Pinus sibirica

通过对西伯利亚红松3个种源与当地红松高生长量的比较,分析在长白山系汪清林区内不同种源西伯利亚红松与当地红松的生长差异,确定了托木斯克州种源适合在本地区大面积推广。经11 a研究,初步掌握了该树种幼年期生长规律,摸索出一整套西伯利亚红松造林技术。

To analyze the growth difference among different geotypes of Pinus sibirica and Pinus koraiensis in Wangqing forest region of Changbai Mountain,the height growth of 3 geotype of Pinus sibirica was compared with that of the native Pinus koraiensis.The Pinus sibirica coming from Tomsk was the suitable geotype for afforestation extension in this area.The growth characteristics of this genotype at juvenile period were primarily mastered through 11 years study,and a whole planting technique for Pinus sibirica was established.
