摘 要:
对14个紫花苜蓿Medicago sativa品种在北京地区的表现进行观测，并对主要性状指标进行分析。结果表明：参试各品种秋眠级不同其春季生长速度、秋季生长速度、产草量及越冬率都有明显的差异，秋眠级高的品种生长速度快、产草量高，但越冬率低、秋眠级低的品种与之相反；地温也影响苜蓿生长速度；茎叶比与鲜干比各品种之间无明显变化，但与茬次有显著变化。[著者文摘]

Abstract:
The main performance indexes of 14 alfalfa varieties were measured and analyzed in Beijing area. The result indicated that the growth rates in spring and autumn, forage yield and over-wintering rate showed significant difference along with different fall dormancy. The varieties with high level of fall dormancy performed higher growth rate, forage yield and lower over-wintering rate. The growth rate of tested alfalfa varieties was affected by soil temperature. The stem/leaf ratio did not show significant difference among varieties, but it was affected by the number of harvest.[著者文摘]
