通过柞树林冠下针阔叶树种生长效果调查和营林技术研究，了解柞树冠下栽植针叶树种的适应能力，为柞树冠下更新可行性提供了技术参考。结果表明：柞树冠下针叶树种的生长量与柞树杂木林的郁闭度有密切关系；调整柞树林的密度和合理确定冠下树种初植密度是保证柞树冠下针阔叶树种生长的重要条件。
通過柞樹林冠下針闊葉樹種生長效果調查和營林技術研究，瞭解柞樹冠下栽植針葉樹種的適應能力，為柞樹冠下更新可行性提供瞭技術參攷。結果錶明：柞樹冠下針葉樹種的生長量與柞樹雜木林的鬱閉度有密切關繫；調整柞樹林的密度和閤理確定冠下樹種初植密度是保證柞樹冠下針闊葉樹種生長的重要條件。

In order to understand adaptation of cultivating coniferous species under crown of Quercus mongolica , growth effect of coniferous & broadleaved species were investigated under crown of Quercus mongolica and its silvi‐culture techniques were studied ,which offer technical reference for feasibility of regeneration under crown canopy of Quercus mongolica .Result shows that growth of coniferous species under crown canopy of Quercus mongolica has close relationship with canopy density of weed trees ;adjusting the density and reasonably determining planting densi‐ty are the important conditions for assuring the growth of coniferous and broadleaved trees under crown canopy of Quercus mongolica .
