| 摘 要： | 为探求适宜在张家口坝下地区生长的苜蓿(Medicago sativa)品种，以德宝、敖汉、中苜1号、三得利、阿尔冈金和金皇后作为试验材料，比较了这些品种前两年的越冬率以及生长第3年的形态学指标。结果表明，播种当年各苜蓿品种的越冬率差异较大，第2年的越冬率较第1年有所提高，且彼此间差别不大;同茬次不同苜蓿品种的株高、分枝数和花序质量均差异显著(P0.05)。苜蓿品种的分枝数和花序质量随茬次变化逐渐降低;苜蓿的株高第2茬最高，1、3茬较低;而干鲜比是第1茬和第3茬较大，第2茬较小。苜蓿植株的主要变异来源于花序质量和分枝数，其次为茎叶比和干鲜比。中苜1号可作为推广品种在张家口坝下地区大面积种植。

| Abstract: | In order to select suitable aflalfa cultivars in Zhangjiakou dam areas, six aflalfa cultivars including Debao, Aohan, Zhongmu No.1, Suntory, Algonquin and gold queen were studied for their winter survial rate in the first two years and morphological indicators in the third year. The difference of winter survial rates between alfalfa cultivars in the first year was significant (P0.05), however, the difference of them was not significant although the winter survial rates of each cultivar increased in the second year. Different alfalfa cultivars had significant difference (P0.05) in height, branch number, inflorescence weight. The branch number and inflorescence weight decreased gradually with the mowing times increase. The height after second mowing was higher than that after first and third mowing. The dry weight/fresh weight (DW/FW) after second mowing was lower than that after first and third mowing. The main variations of alfalfa firstly come from inflorescence weight and branch number, and then come from DW/FW and stem weight/leaf weight ratio. Zhongmu No.1 were suitable cultivar in Zhangjiakou dam areas. |
