摘　　要：在福建省三明市岩前林业站苗圃开展不同种植密度、不同遮荫度条件下的草珊瑚育苗试验,结果表明:不同播种密度、不同遮荫度对草珊瑚幼苗的苗高影响均达极显著水平(P<0.01),对地径、根系长度、根系数量影响均达显著水平(P<0.05)。以播种密度120株.m-2、遮荫度75%条件下,草珊瑚平均苗高、地径、根长以及根数均为最优。The seedling growth experiment of Sarcandra labra was finished from different sowing densities and shading rates at Yanqian Forestry Working Station of Sanming City of Fujian Province.The results showed the seedling heights were extremely significant(P<0.01) with different sowing density and shading rate,the ground diameter and root length and root quantity were significant(P<0.05).When the sowing density was 120 individual per square meter and shading rate was 75%,the seedling growth indexes were the highest,which were the height,ground diameter,root length and root quantity.
