摘　　要：为促进苜蓿品种的推广应用,在哈尔滨地区,以10个紫花苜蓿不同品种作为研究对象,对其在现蕾期的鲜草干草产量、株高、分枝数、粗蛋白、酸性洗涤纤维、中性洗涤纤维含量进行测定分析,并采用灰色关联度法进行综合评价。结果表明:产量方面超新里鲜、干重最高,达35295.46和12386.50 kg·hm^-2;龙牧806株高最高(101.33 cm);按整个生长季计算,龙牧806品种生长速度快;超新里单株分枝数最多,达到18.67个;粗蛋白含量最高的品种是2065FM(19.56%),图苜粗蛋白含量最低(15.03%);相对饲料价值农菁1号最高(166.06);综合生产性能表现较好的品种依次为:超新里、龙牧806和农菁1号,这些品种在上述各地区分别具有较高的推广利用价值。In order to promote the popularization and application of alfalfa varieties,in Harbin area,10 different varieties of alfalfa were used as the research objects to determine the content of fresh,hay yield,plant height,branch number,crude protein,acidic washing fiber,and neutral washing fiber in the squaring stage.The grey correlation degree method was used for comprehensive evaluation.The results showed that the maximum yield of Chaoxinli fresh and dry weight was 35295 and 46,12386.5 kg·hm^-2;Longmu 806 had the highest height of plants(101.33 cm);According to the entire growth season,Longmu 806 variety grow fast;The number of branches per plant in Chaoxinli was the largest,reaching 18.67;The species with the highest crude protein content was 2065FM(19.56%),and the Tumu has the lowest crude protein content(15.03%);Relative feed value Nongjing No.1 was the highest(166.06);The varieties with good comprehensive production performance were:Chaoxinli,Longmu 806 and Nongjing No.1,which have a high promotion and utilization value in the above regions.
