摘要
调查大兴安岭塔河蒙克山高寒地上的西伯利亚红松引种试验林,其连年生长量稳步提高,19 a生平均树高3.75 m,2008年高生长平均已达51.2 cm,其生长量与生长在气候相对温和的"红松故乡"温带的小兴安岭东南坡带岭地区的近缘种红松几乎相同。而试验区内的对照红松已经所剩无几,幸存的几株也呈灌丛状。说明西伯利亚红松是耐严寒、耐贫瘠、引种前景广阔的优良树种。
Pinus sibirica Du Tour introduction experimental forest on high-cold land of Daxing＇anling Mountain Mengke Mountain in Tahe was investigated and the results showed that current armual increment grew up steadily. The average height of 19-year-old trees was 3.75 m and the growth of height had reached an average of 51.2 cm during 2008. The growth of Pinus sibirica Du Tour was similar to the Pinus koraiensis in Dailing area where located on southeast hillside of Xiaoxinganlin Mountain which was known as the hometown of Pinus koraiensis. However, the few control Pinus koraiensis trees had left and shaped in shrubs in the Mengke Mountain experimental site. The investigation showed that Pinus sibirica Du Tour was really cold-resistant and barren soil-resistant species, with broad prospects for introduction.
