采用红豆草与鸭茅、红豆草与无芒雀麦2个豆科牧草混播组合,每个组合设比例为5∶5,4∶6和6∶4的3种处理,分别设置1∶1行,2∶2行和3∶3行的异行建植方式,在豆科牧草初花期与禾本科牧草抽穗期及再生草停止生长前,通过刈割测定草地群落各种群组分的产草量及牧草营养成分的变化,研究采用间行混播的建植方式,对草地群落稳定性与主要生产性能的影响。结果表明：在混播牧草组合中,红豆草与鸭茅的混播组合在产量与品质上均高于红豆草与无芒雀麦；在1∶1行的建植上,其各项经济性状指标均优于其他建植方式；在混播比例上,红豆草与鸭茅组合,以4∶6的草群产量最高,平均可产干草1060.24 g/m2；红豆草与无芒雀麦组合,以6∶4与5∶5比例的草群产量最高,平均干草产量达到1026.72 g/m2与913.24 g/m2。在草地牧草营养品质上,红豆草与鸭茅在混播比例4∶6、建植方式2∶2行及混播比例6∶4、建植方式3∶3行的组合,牧草品质优于其他组合；而在红豆草与无芒雀麦组合中,表现出以混播比例6∶4建植方式3∶3行的营养价值为最高。

The mixing patterns of legume/grass of Onobrychis viciifolia +Dactylis glomerata and Onobry-chis viciifolia +Bromus inermis at the sowing ratio of 5∶5,4∶6 and 6∶4,with 1∶1;2∶2 and 3∶3 line intervals <br> were designed.The yield and community composition were measured by the end of flowering and heading peri-ods.The result indicated that Onobrychis viciifolia +Dactylis glomerata was better than Onobrychis viciifolia+Bromus inermis at the stands of both production and quality.And 1∶1 line interval was the best.Meanwhile, the yield of mixing ratio 4∶6 was higher than others and the average yield was 1 060.24 g/m2 in Onobrychis vici-ifolia +Dactylis glomerata .And it was 6∶4 and 5∶5 (1 026.72 g/m2 and 913.24 g/m2 )in Onobrychis viciifolia+Bromus inermis .As for forage quality,the best treatments were 4∶6 (mixing ratio)and 2∶2 (line interval)and 6∶4 and 3∶3 in Onobrychis viciifolia +Dactylis glomerata .And they were 6∶4 and 3∶3 in Onobrychis viciifolia+Bromus inermis .
