摘　　要：采用分期播种试验(5,10,15,20℃)研究比较了6个不同休眠级的苜蓿的生长特性和生产性能,结果表明:苜蓿的休眠性与生育期(出苗、返青、开花)、生长速度、再生性、越冬率、产草量关系比较密切。半休眠品种出苗早、生长速度快、再生能力强、产草量高,但返青迟,越冬率较低。休眠级为4和5的品种适宜在太原地区种植。Sowing in stages at different temperatures (5,10,15,20℃), the growth characteristics and yield of six kinds of alfalfa varying in level of falldormancy were studied There was quite a close relationship between the dormancy nature of the alfalfa and growth period (emergence, return to green, blossom), growth rate, reproduction, over wintering survival rate and vegetation yield Semidormant varieties were early emerging, fast growing, had strong reproduction and had high vegetation yield, but returning to greenness was late and over wintering survival rate was quite low Alfalfa varieties with a dormancy class of 4 or 5 were suitable for cultivation in Taiyuan
