摘　　要：为了保护和开发利用壳斗科紫玉盘柯植物,培育紫玉盘柯苗木。通过种子贮藏、解剖、播种和出苗率统计,研究了紫玉盘柯种子的萌发,对比了不同重量和沙藏深度的紫玉盘柯种子播种出苗率。结果表明,紫玉盘柯种子易萌发,通过育苗袋点播培育紫玉盘柯苗木的技术难度不大;种子大小对出苗率影响不明显,中层深度(20-25 cm)沙藏的种子出苗较早,整齐性好。In order to protect,develop and utilize Lithocarpus uvariifolius,the seedlings was cultivated.The germination of Lithocarpus uvariifolius seeds was studied by seed storage,dissection,sowing and statistical emergence rate.The sowing and emergence rates of Lithocarpus uvariifolius seeds with different weight and sand storage depth were compared.The results showed that the seeds of Lithocarpus uvariifolius were easy to germinate,and it was not difficult to cultivate ziyupanke seedlings through seedling bag on demand.The effect of seed size on the emergence rate was not obvious.The seeds stored in sand at the middle depth(20-25cm)emerge earlier with good uniformity.
