摘　　要：为筛选适合于夏河农牧交错区小黑麦(Secale cereale L.)与豆科牧草的混播组合及比例,以及在不同肥力条件下生产性能的差异,本试验研究了‘甘农2号’小黑麦(‘Gannong No.2’Triticale variety)与3种豆科牧草(‘加拿大’饲用豌豆(‘Canadian’forage peas)、‘青海’箭筈豌豆(‘Qinghai’common vetch)和‘绿箭1号’箭筈豌豆(‘Lvjian No.1’common vetch))不同比例(100∶0,80∶20,70∶30,60∶40,50∶50,40∶60,30∶70,20∶80,0∶100)混播时的生产性能。结果表明:土壤肥力对小黑麦和豆科牧草混播草地的草产量有显著影响;土壤贫瘠条件下,‘甘农2号’小黑麦与‘绿箭1号’箭筈豌豆以50∶50的比例混播时干草产量最高(13.97 t·hm^(-2));土壤肥力状况较好时,‘甘农2号’小黑麦与‘青海’箭筈豌豆以80∶20的比例混播时,干草产量最高(16.45 t·hm^(-2))。该研究对于提高夏河农牧交错区禾-豆混播的生产性能具有重要意义。To screen the optimum mixture model of triticale and legumes and the differences in production performance under different fertility conditions in the farming-pastoral ecotone of Xiahe,this experiment was conducted to study the production performance of‘Gannong No.2’triticale variety mixed with three kinds of legumes(‘Canadian’forage peas,‘Qinghai’common vetch and‘Lvjian No.1’common vetch)at different ratios(100∶0,80∶20,70∶30,60∶40,50∶50,40∶60,30∶70,20∶80,0∶100),respectively.The results showed that the fertility of the soil greatly affected the forage yield;When the soil was poor in fertility,the highest hay yield could be obtained while‘Gannong No.2’triticale variety mixed with‘Lvjian No.1’common vetch variety at a ratio of 50∶50(13.97 t·hm^(-2)),and when the soil was rich,the highest hay yield could be obtained while‘Gannong No.2’triticale variety mixed with‘Qinghai’common vetch variety at a ratio of 80∶20(16.45 t·hm^(-2)).
