摘　　要：设置了4种不同的遮光处理(全光照、遮光度40%、遮光度60%、遮光度70%),探讨不同遮光度对赤皮青冈播种育苗苗木存活率和苗木生长的影响。结果表明:遮光度对赤皮青冈苗木存活率和苗木生长有显著影响;遮光度达70%时,其苗木存活率、苗木高生长与地径生长均表现最佳。Four shading treatments （full light, 40% shading rate, 60% shading rate, and 70% shadig rate ） were set to investigate the effects of different shading luminosity on the seedling survival and growth condition of Cyclobalanopsis gilva field sowing and seedling. The results show that there were significant influences in seedling survival and growth condition under various shading treatments; the treatment of 70% shading rate was the best for seeding survival, seedling height and ground diameter C. gilva field sowing and seedling.
