摘要
为了筛选出在我国东北部寒旱区适宜种植的苜蓿(Medicago sativa)品种,在呼伦贝尔地区开展了35份国内外苜蓿品种适宜性研究,于2013-2015年进行定位测定与样品采集,主要对干草产量与营养品质指标(粗蛋白、酸性洗涤纤维、中性洗涤纤维)进行分析比较。结果表明:35个品种的综合生产力状况和营养价值均存在差异(P<0.05),产量最高的品种为55V12(3年均值达16 205.56kg·hm-2),最低的品种为WL712(3年均值为7 788.89kg·hm-2);综合3年粗蛋白含量平均最低的品种为59N59(平均含量19.76%),中性洗涤纤维和酸性洗涤纤维平均含量最低的品种都为WL363HQ(含量分别为33.43%、21.59%);从产量与营养品质综合角度看,表现良好的品种有骑士-2、MF4020、皇冠、巨能耐盐、标靶和阿迪娜,适宜在我国东北部寒旱区推广种植。
To determine suitable alfalfa varieties for local production in cold and arid regions of northeast China,35 varieties of alfalfa(Medicago stavia)were selected in this experiment in Hulun Buir.Location determination and sample collection were conducted simultaneously from 2013 to 2015.For this study,mainly analyses were conducted on the hay yield and its nutritional quality[crude protein(CP),nearal detergent fiber(NDF),acid detergent fiber(ADF)].The results showed that there were differences both in production and nutrient content of all varieties(P<0.05).The highest hay yield was for 59N59(three-year average was 16 205.56 kg·ha-1)and the lowest was for WL712(three-year average was 7 788.89 kg·ha-1).Comprehensively over the three years,the lowest average CP was for 59N59(the average was 19.76%),both the lowest average of NDF and ADF were for WL363HQ(the averages were 33.43%and 21.59%,respectively).Knight No.2,MF4020,Phabulous,Magnum VI-Wet,Target,and Adrena were more suitable alfalfa varieties that could be more widely planted than others in this area.
