摘要: 为评价不同苜蓿品种的生产性能,筛选能够适应东北地区种植的紫花苜蓿品种,笔者对吉林省东部地区14个国内外紫花苜蓿(Medicago sativa L.)品种播种当年生育期,生长第2年的越冬率及不同茬次的株高、鲜草产量、干草产量、茎叶比等各项农艺性状指标的差异通过灰色关联分析进行比较。结果显示:各品种生育期差异不显著,翌年‘陇中苜蓿’、‘甘农3号’、‘甘农6号’返青较早;‘WL525HQ’、‘WL712’、‘WL656HQ’、‘WL903’越冬率较低且产量及综合评价较低,不适于在吉林省东部地区推广种植;‘WL440HQ’、‘甘农3号’、‘甘农6号’、‘WL168HQ’的越冬率较高且综合评价中表现良好,适合在吉林省东部地区广泛推广种植。

Abstract: To evaluate the performance of different alfalfa (Medicago sativa L.) varieties and select alfalfa varieties can be planted in Northeast part of China. Performance test to compare the differences in winter surviving ratio, fresh yield, plant height, hay yield stem to leaf ratio were conducted and evaluated with gray correlation analysis with 14 domestic and introduces alfalfa varieties. The results indicated that there were no differences among varieties in groeth period in the first year. WL525HQ、WL712、WL656HQ、WL903 with lower winter surviving rates and not suitable to be extended in east area of Jilin province. WL440HQ、Gannong No.3、Gannong No.6 and WL168HQ with excellent comprehensive characteristics and higher winter surviving rate were more suitable of east area of Jilin province.
