%X 在西藏河谷区，将箭筈豌豆（Vicia sativa L.）与燕麦（Avena sativa L.）种子按照不同比例进行田间混、间作试验，通过对混收牧草产量和营养品质的测定与比较，筛选出适宜当地生长的箭筈豌豆与燕麦的最佳播种比例。结果表明：1）与单播相比，混、间作均能提高产量，还可显著提高箭筈豌豆的株高，但对燕麦株高的影响不显著；2）混、间作处理的粗蛋白（crude protein, CP）含量和箭筈豌豆的播种量成正比，且均高于单播燕麦，其中单播箭筈豌豆CP含量最高（21.9%），单播燕麦最低（5.5%）；3）混、间作均能提高中性洗涤纤维（neutral detergent fiber, NDF）和酸性洗涤纤维（acid detergent fiber, ADF）含量，分别提高了27.3%～43.5%和2.4%～17.6%，且随着箭筈豌豆播种量的增加，NDF含量呈降低趋势而ADF含量则相反。根据产量与营养品质的测定结果，并通过模糊数学的隶属函数法进行综合评价，表明混播较间作更能表现出产量与营养品质上的优势，其最佳混播比例为箭筈豌豆60%+燕麦40%，适宜在西藏河谷区推广应用。 通讯作者: 邵小明（https://orcid.org/0000-0001-8545-4519） E-mail: shaoxm@cau.edu.cn</br>Abstract: In valley area of Tibet, seeds of common vetch (Vicia sativa L.) and oat (Avena sativa L.) were sowed at different ratios in mixtures and intercropping. The forage yield and nutritional quality of common vetch and oat were analyzed and compared, and the optimal sowing ratio of them which was suitable for the local conditions was selected. The results were showed as follows: 1) Compared with monoculture, mixture and intercropping increased the yields, and significantly increased the height of common vetch, but had no significant effect on the oat. 2) In all mixtures and intercropping groups, the crude protein (CP) content was increased with the increasing of seeding proportion of common vetch, and higher than that of monocultured oat. Among them, the monocultured common vetch had the highest CP content (21.9%), while the CP concent of monocultured oat was the lowest (5.5%). 3) Mixture and intercropping both increased the contents of neutral detergent fiber (NDF) and acid detergent fiber (ADF) in common vetch and oat, which increased by 27.3%-43.5% and 2.4%-17.6%, respectively. Moreover, the NDF content was increased as the seeding proportion of common vetch increasing, which was similar to the change of CP content; while the change trend of ADF was on the contrary. Based on the above results and the analysis of fuzzy mathematics membership function, it is indicated that the mixture of common vetch and oat performs more advantages on the forage yield and quality than intercropping as well as monoculture, and the optimal mixture ratio is common vetch 60% and oat 40%, which is suitable for application in valley aera of Tibet. Key words: Tibet common vetch oat mixture cropping intercropping yield nutritional quality
