摘　　要：为了研究燕麦与箭筈豌豆不同混播模式的增产效应。在农业部兰州黄土高原生态环境重点野外科学观测试验站对一年生牧草燕麦和箭筈豌豆进行了混播试验。结果表明：丹麦444燕麦50%和333/A春箭筈豌豆50%的混播处理,地上生物量、种子产量及0~50cm的地上生物量均最高,分别为22193.33、4776.67、11792.90kg/hm2,且与其他混播处理的差异显著（P〈0.05）。该混播模式具有较好的协同效应,可在黄土高原及类似地区推广应用。In order to improve the yield of the mixture artificial grassland of oat and vetch. This study was conducted at the Lanzhou scientific observation and experiment field station of ministry of agriculture for ecological system in Loess Plateau Areas. The results showed that it was the most suitable mixture that the treatment of Avena sativa cv. Danmark 444 of 50% and Vicia sativa cv. 333/A of 50%, the above-ground biomass, seed yield and the underground biomass from 0-50 cm soil layer were all the highest, above-ground biomass was 22193.33 kg/hm2, seed yield was 4776.67 kg/hm2, underground biomass was 11792.90 kg/hmz, and the difference was significant compared with other treatments （P〈0.05）. The miixture model had good synergistic effect and could be used for application and extension in the Loess Plateau and the similar area.
