本文对阔叶红松林红松天然更新固定观察研究结果进行阐述,红松天然更新数量在柞树红松林中最多,椴树红松林中次之,枫桦红松林和云冷杉红松林中最差。四个林型红松天然更新1—5年生的幼苗数量分别为其总更新株数的96%、86%、87%、82%,当年生的幼苗又占绝对优势。鼠类、鸟类,球蚜、立枯病、红松落叶病等这些病虫及动物的危害严重影响着红松天然更新的发生发展。研究成果为红松林恢复提供理论依据。
In this paper, the results of the observation of natural regeneration of Korean pine in broad-leaved Korean pine forest were described. The natural regeneration of Korean pine was the most in Korean pine forest, the second was in Korean pine forest, the worst was in Korean pine and Korean pine forest. The four tree-type Korean pine natural regeneration 1-5 year-old seedlings were 96%, 86%, 87%, 82% of the total number of trees, annual seedlings again accounted for absolute advantage. The pest and animal hazards such as rodents, birds, aphids, blight, koraiensis deciduous disease seriously affect the occurrence and development of natural regeneration of korean pine. The research results provide the theoretical basis for the recovery of Korean pine forest.
