摘　　要：就青海云杉强化育苗的基质配比进行改进,结果表明改进后的基质和原基质相比,高生长和地径生长无显著差异,在改进后的基质中培育出的苗木未发生猝倒病和立枯病。而且从成本上分析,采用改进后的基质,使用轻基质网袋容器成本降低24%;使用塑膜杯容器成本降低30%,使用育苗盘容器成本降低28%。The medium ratio were improved of accelerating spruce improved medium compared with original medium height and ground reached obvious difference, the seedling grew on improved medium have by medium cuhtvition container the cost reduced 24%, by plastic films nursery trays the cost reduced 28%. seedling growth, the results showed diameter growth difference have not not damping-off and seedling blight, container the cost reduced 30%
