【摘要】 通过林下栽植红松,增加其在林分中的优势度,是加快小兴安岭天然次生林向阔叶红松林恢复进程的重要手段。然而,长期以来,小兴安岭天然次生林林下栽植红松时,没有考虑区域内不同地点对红松良种造林效果的影响,存在不适红松品种造林后适应差和生长量低等现象。针对上述问题,以小兴安岭丽林实验林场(北部)、带岭林业实验局(中部)及双丰林业局(南部)3个地点为代表,进行了次生林下红松种源试验研究,结果表明:不同地点之间,红松各种源地径、树高、3年高、当年高和保存率均存在显著差异;地点与种源在地径、树高和当年高性状上存在极显著交互作用;丽林和带岭试点铁力种源最优,双丰试点鹤岗种源最优。更多还原

【Abstract】 To accelerate the recovery to broad-leaved Pinus koraiensis forest, it is an important method to increase its dominance through artificial afforestation in natural secondary forest. However, it has been not considered that the different locations have important effects on the growth of Korean pine varieties, and Korean pine plantation has the disadvantages of poor adaptability and low growth, which are caused by unsuitable Korean pine varieties. To solve these problem above, the provenance experiment of Korean pine in natural secondary forest was carried out in three sites, including Lilin Experimental Forest Station(North), Dailing Forestry Experimental Bureau(Central), and Shuangfeng Forestry Bureau(South) of Xiaoxing’an Mountains. There were significant or extremely significant differences in diameter, tree height, seven-year height, current year height, and preservation rate of Korean pine among three sites; there were significant interactions between sites and provenances in diameter, tree height and current year height; Tieli provenance is the best provenance of Korean pine in Lilin Forest Farm and Dailing Forestry Bureau, and the Hegang provenance exhibits the best performances in Shuangfeng Forestry Bureau.更多还原
