摘　　要：心叶驼绒藜仅分布在我国的新疆。本研究采用6种不同深度播种,探索播种深度对心叶驼绒藜出苗的影响。试验结果表明:适宜的播种深度为不覆土或覆土0～2cm,平均出苗率13.85%;而覆土4～8cm时,平均出苗率仅为1.14%,两者相差12.15倍。Caretoides ewermanniana (Stschegl. Ex Losinsk.) Botsch. Et Ikonn only distributed in Xinjiang region. The research measured 6 different sowing depths to study its germination status. The result shows that, the best suitable sowing depth is 0-2cm with or without earth up, the average germination rate is 13.85%; to 4-8cm earth up, the germination rate is 1.14%. The different in between is 12.15 times.
