摘　　要：箭筈豌豆(Vicia sativa)是一种优良的肥饲兼用型绿肥作物,具有生物量大、适口性好、营养价值高、再生性强等优势,在生育期内可多次刈割,经济价值极高。本研究对25份箭筈豌豆种质资源的主要性状、产量和品质进行相关性分析,并运用灰色关联分析法对箭筈豌豆的主要性状、营养品质和固氮能力进行综合评价,以期为青海地区筛选出优良箭筈豌豆品种。结果表明,25份箭筈豌豆种质资源农艺性状和品质性状差异明显,育种潜力较高;生育期与株高、茎粗、鲜草产量、地上部干重、地下部干重、氮携出量、粗蛋白产量、中性洗涤纤维和酸性洗涤纤维极显著正相关,与相对饲喂价值极显著负相关;鲜草产量与生育期、茎粗、氮携出量、粗蛋白产量极显著正相关;地上部干重和地下部干重均与氮携出量和粗蛋白产量极显著正相关,田间试验中应着重筛选生育期适中、株高较高、茎粗较大、鲜草产量和干草产量较大的品种。灰色关联分析结果显示,‘西牧333’‘清水河麻箭豌’‘师宗箭豌’‘苏箭5号’和‘7401箭豌’的营养性状和固氮能力较优,在青海地区生产性能表现较好,适宜进行推广种植。Vicia sativa is an useful green fertilizer crop which has the advantages of high biomass,high palatability,high nutritional value,and strong reproducibility.During the growth period,V.sativa can be cut multiple times and it has considerable economic value.In this study,yield and quality of 25 varieties of V.sativa were examined through correlation analysis.This detailed evaluation was conducted on the main traits,nutritional quality,and nitrogen fixing capacity of different varieties of V.sativa using grey correlation analysis.The research purpose was to screen for the most suitable V.sativa varieties for green fertilizer planting in Qinghai.In this study,there were significant differences in agronomic traits and quality traits of the 25 varieties of V.sativa,which indicated high breeding potential.Correlation analysis showed that growth period was significantly positively correlated with plant height,stem diameter,fresh grass yield,above-ground dry weight,underground dry weight,nitrogen carrying capacity,crude protein yield,neutral detergent fiber,and acid detergent fiber.However,it was significantly negatively correlated with relative feeding value.The fresh grass yield was positively correlated with growth period,stem diameter,hay yield,nitrogen transport,and crude protein yield.Above-ground dry weight and underground dry weight were positively correlated with nitrogen transport and crude protein yield.In field trials,the emphasis should be placed on selection of varieties with moderate growth period,higher plant height,larger stem diameter,and higher yields of fresh grass and hay.The results from grey correlation analysis showed that‘Ximu 333’‘Qingshui River common vetch(linen)’‘Shizong common vetch’‘Sujian 5 common vetch’,and‘7401 common vetch’had more suitable nutritive traits and nitrogen fixing ability.These varieties had a high level of production performance in Qinghai Province.Therefore,they were found to be suitable for widespread cultivation.
