摘　　要：在实验室、试验地和大田中,对青海祁连湿地金露梅种子给予不同温度、不同播种深度、不同密度、不同季节播种试验处理,观测其种子发芽率、发芽势、出苗率、成苗率及越冬率。结果表明：金露梅种子萌发的最适温度15-25℃;最适播种深度1.0cm;最适播种密度1 500-2 000g/667m^2;春天播种后苗的越冬率达96.8%。综上,青海祁连湿地高海拔金露梅种子在适宜的条件下可以在低海拔大通地区大田中正常生长。In Qinghai Qilian wetland Potentilla fruticosa seed germination rate, germination potential, seedling emergence rate and wintering rates were observation under different temperature, sowing depth, density and season sowing treatment in laboratory, testing plot and field. The results showed that the germination of potentilla fruticosa optimum temperature of 15-25℃ ;the optimum sowing depth of 1 cm; the optimum planting density of 1 500-2 000 g/667m^2 ;the planting seedling rate in spring of 96. 8%. In conclusion,the Potentilla fruticosa seed of Qinghai Qilian wetland in high altitude could grow normally in low altitude fields of Datong.
