摘　　要：通过开展蒙古栎幼苗期不同程度遮阴试验,定期对蒙古栎不同处理土壤温湿度、幼苗生长情况(受害程度、苗高、地径)开展动态调查监测,研究不同遮阴处理对夏季低海拔地区蒙古栎幼苗叶片变黄、焦边的受害程度以及幼苗生长情况的影响。结果表明,蒙古栎在幼苗期,遮阴条件下,2层遮阴网处理受害程度最轻,植株长势最好。In order to study the effects of different shading treatments on the normal growth of Quercus mongolica seedlings,we designed the experiment of shading in different degrees at the young seedling stage,and implemented dynamic investigation on the soil temperature and humidity,and the growth of Quercus mongolica seedlings(damage degree,seedling height,ground diameter).The results showed that the treatment covered in two layers of shading(the initial light intensity was 298.64μmol m^(2)/s)was less damaged and the plants growth was the best.
