| 摘 要： | 沙地云杉(Picea mongolica)是中国特有树种，为了更好地保护这一植物资源，在田间条件下，运用正交试验的设计方法，研究了覆沙厚度、播种密度、覆盖材料3个因素对沙地云杉出苗率的影响。结果表明：试验中的最佳组合为以10 mm覆沙厚度、300粒/行的播种密度配合河沙土为覆盖材料最好，组合出苗率也最高；在干旱沙区覆沙厚度和覆盖材料对沙地云杉播种育苗的影响极显著，播种密度对沙地云杉播种育苗也有不同程度的影响。

| Abstract: | Picea mongolica is an endemic species in China. In order to better protect this plant resources, using the orthogonal experimental design method, the seedling emergence rate at the different burial depths, planting density and cover material were researched under field condition. The results showed that: the best combination for tests was that the 10 mm burial depths and 300 per row sowing density with the river sand cover material, and the germination rate of combination was also the highest. In the arid desert region, burial depths and cover material had significant influence on the seedling emergence rate of Picea mongolica, planting density also had some influence in a way. |
