摘　　要：笔者研究了不同郁闭度条件下辽东栎幼苗的生长状况,发现遮阴能够提升辽东栎幼苗的成活率,郁闭度为0.5时辽东栎幼苗生长最好。在林内补植辽东栎或进行幼苗培育时,通过择伐或者遮阴实现0.5的郁闭度环境,能够有效提升辽东栎幼苗的生长水平和苗木质量。By studying the growth of Quercus liaotungensis seedlings under different canopy density, it was found that shading could improve the survival rate of Quercus liaotungensis seedlings. Quercus liaotungensis seedlings grew best when the canopy density was 0.5. When planting Quercus liaotungensis in the forest or cultivating seedlings, setting canopy density at 0.5 through selective cutting or shading could effectively improve the growth level and seedling quality of Quercus liaotungensis seedlings.
