摘　　要：以马蹄荷播种苗为试材,研究不同遮光度对1年生苗木高度和地径生长的影响。结果表明:45%和55%这2种遮光度对马蹄荷播种苗的苗高和地径生长均有极显著促进作用,65%和75%这2种遮光度对马蹄荷播种苗的苗高生长有极显著的促进作用、对地径生长无显著促进作用,其中不论苗高还是地径生长均在55%遮光度下效果最好。综合遮光度对马蹄荷苗高和地径生长的影响,培育马蹄荷1年生播种苗以55%左右的遮光度为好。One-year-old Exbucklandia populnea seedlings were shaded to study the effects of different shading densities on the seedling seedling height and ground diameter growth. The results showed that shading densities of 45% and 55% had very significant promoting effects on seedling height and ground diameter growth of E.populnea .Shading densities of 65% and 75% had very significant promoting effects on height, however,but no significant promoting effects on ground diameter growth. E.populnea seedling grew best under 55% shading density. Comprehensive analysis showed that shading of about 55% was the best way to cultivate one-year-old seedlings of E.populnea.
