摘要: 2013-2016年通过田间试验,在中国农业大学涿州教学实验场对22个紫花苜蓿品种的产量性能进行比较分析,以期筛选出适宜河北地区种植的苜蓿品种。结果表明,不同年份的苜蓿年干草产量具有极显著差异(P<0.01);建植当年各苜蓿品种平均年产量最低,随着生长年限的延长,产量总体呈增加趋势;‘中苜5号’的4年总干草产量最高,‘SR4030’等6个品种的总产量低于对照品种‘中苜1号’,但与对照差异不显著;第1茬产量最高,随着茬次的增加产量呈下降趋势,第1茬与年产量之间的关联度最高;秋眠性3~6级的品种丰产性和产量稳定性综合评价较高。综合4年试验结果,‘中苜5号’、‘中苜1号’、‘SR4030’、‘巨能551’、‘BR4010’、‘MF4020’、‘SK3010’和‘WL363HQ’产草量高,具有潜在的推广价值,适宜在河北地区大面积推广应用。

Abstract: To select appropriate alfalfa cultivars in Hebei area, field trails were conducted at the Zhuozhou teaching experimental field of China Agricultural University to evaluate the hay yield of twenty-two alfalfa (Medicago sativa L.) cultivars from 2013 to 2016. The results showed that the yield of hay in different years were significantly different (P<0.01). The average annual yield of each alfalfa variety was the lowest in the year of the establishment,and the annual yield showed an overall increasing trend with the extension of the growing years. The cultivar of ‘Zhongmu No.5’ obtained the highest total hay yield in four years. The total yields of ‘SR4030’ and other 5 varieties were lower than that of the control variety ‘Zhongmu No.1’,but there were no significant differences among them. The yields of different harvests were significantly different (P<0.01),and the yield of the first harvest was the highest,and the yields showed a downward trend from the first to the fourth harvest. The correlation coefficient between the yield of first harvest and annual yield was the highest. Based on the comprehensive evaluation of yield and yield stability,the varieties with fall dormancy 3 to 6 grade were better than the other varieties. The four-years results showed that ‘Zhongmu No.5’ and ‘Zhongmu No.1’ were suitable to be cultivated for alfalfa hay production in Hebei area,and six imported cultivars,including ‘SR4030’,‘Magna551’,‘BR4010’,‘MF4020’,‘SK3010’ and ‘WL363HQ’ also had excellent production performance.
