摘　　要：采用对盐肤木种子3种遮阴强度和4种土壤基质多种处理进行穴盘播种育苗试验,研究不同处理对盐肤木种子发芽率和发芽势的影响。结果表明:MLI(一层4针黑色遮阳网,遮阴50%~60%)和混合土环境(砂土∶腐殖质=3∶1)对盐肤木种子的萌发促进效果最优,发芽率和发芽势分别达到80.83%和40.83%。In this experiment,three kinds of shading intensity and four kinds of soil matrix were used to carry out plug seeding and seedling test to study the effects of different treatments on the germination rate and germination potential of Rhus chinensis seeds.The results showed that MLI(a layer of 4 needles black sunshade net,shade 50%-60%)and mixed soil environment(sand∶humus=3∶1)had the best effect on the germination of seeds,and the germination rate and germination potential reached 80.83%and 40.83%,respectively.
