| 摘 要： | 比较了12个紫花苜蓿Medicago sativa品种在沈阳地区的表现,并对主要性状指标进行了分析.结果表明:参试各品种青干草产量存在极显著差异,而茎叶比、鲜干比2个基本指标各品种之间无明显差异.鲜干比与茎叶比呈极显著负相关,可以依据茎叶比估计鲜干比,反过来,也可以根据鲜干比估计茎叶比;青干草产量与平均增长速度之间存在极显著正相关,可以依据苜蓿的生长速度估计产草量.

| Abstract: | Performance of 12 Medicago sativa species in Shengyang was compared, indexes of main characters were analyzed, and the results showed that: green hay yield between all varieties tested had significant difference, while there were no significant difference of stem/leaf ratio and fresh/dry ratio. Fresh/dry ratio and stem/leaf ratio were negatively correlated with great significance, enabling (fresh/dry) ratio to be estimated based on stem/leaf ratio; conversely, stem/leaf ratio could also be estimated based on fresh/dry ratio; green hay yield and average growth speed had very significant positive correlation, forage yield might be estimated based on the growth speed of Medicago sativa. |
