摘　　要：试验旨在研究石河子地区不同秋眠级紫花苜蓿的营养品质和生产性能,以获得适宜当地种植的优良休眠型苜蓿品种。选择10个不同秋眠级紫花苜蓿品种为试验材料,测定紫花苜蓿初花期的营养品质、生产指标和越冬率,并进行综合评价。结果表明,以渝苜1号为代表的第一类群非秋眠型和极非秋眠型苜蓿的生产性能和营养品质均为优,但越冬能力较差,半秋眠型(新疆大叶、Victoria和Archer)苜蓿的越冬性较强且综合性能表现良好,秋眠型(肇东、新牧2号和骑士2)苜蓿的越冬能力强,但综合性能较差。研究表明,综合考虑当地气候及苜蓿多年生的特性,应优选综合性能较好且越冬能力较强的半秋眠苜蓿(新疆大叶、Victoria和Archer)进行种植。The experiment was to study the nutritional quality and production performance of alfalfa with different autumn dormancy grades in Shihezi area,to obtain excellent dormancy alfalfa varieties suitable for local planting.Ten alfalfa varieties with different autumn dormancy levels were selected as experimental materials.The nutritional quality,production index and overwintering rate of alfalfa in early flowering period were determined and evaluated comprehensively.The results showed that the first group of non-autumn dormancy and extreme non-autumn dormancy alfalfa,represented by Yumu No.1,had excellent production performance and nutritional quality,but poor wintering ability.Semi-autumn dormancy alfalfa(Xinjiang Daye,Victoria and Archer)had strong wintering ability and good comprehensive performance.Autumn dormancy alfalfa(Zhaodong,Xinmu No.2 and Qishi No.2)had strong wintering ability,but its comprehensive performance was poor.The study indicates that considering the local climate and perennial characteristics of alfalfa,semi-autumn dormancy alfalfa(Xinjiang Daye,Victoria and Archer)with good comprehensive performance and strong wintering ability should be optimized.
