兴安落叶松(Larix gm-elini Rupr.)是我国寒温带落叶针叶林带的优势种和建林种,主要分布于大兴安岭山地,是我国最主要的供材树种。由于自然和技术上的原因,兴安落叶松种子不能保证更新造林的需要。特别是1987年发生“5·6”特大森林火灾之后,种子短缺已成为恢复森林的最重要限制因素。因此,深入研究兴安落叶松种子发芽的生态学特 Larix gmelinii (Larix gm-elini Rupr.) Is the dominant species and plantation species in the cold temperate deciduous coniferous forest belt in China, mainly distributed in the Greater Xing’an Mountains. It is the most important tree species in our country. Due to natural and technical reasons, Larix seeds can not guarantee the need for reforestation. Especially after the “5.6-magnitude” forest fire broke out in 1987, the shortage of seeds has become the most important constraint to the restoration of forests. Therefore, in-depth study of the ecological characteristics of larch seed germination
