摘 要:2013~2016年通过田间试验,对国内外15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,不同年份的苜蓿年产量具有极显著差异(P<0.01);15个苜蓿品种中4年平均年产量(干重)居前三位的是中苜3号、中苜2号和WL712HQ,分别为14423.1kg/hm2、13706.3kg/hm2、13144.3kg/hm2。4个茬次的干草产量存在显著差异(P<0.05),第1茬的产量最高,约占年总产量的38%,第4茬产量最低,年产量最高的两个品种的第一茬产量也最高。第一茬与年产量之间的关联度最高。综合4年的结果,筛选出适宜河北地区种植的苜蓿品种为中苜3号和中苜2号,国外品种中WL712HQ、WL903HQ和MagnumVI表现良好。To select appropriate alfalfa cultivars in Hebei area,a field study was conducted to evaluate the hay yields of fifteen alfalfa(Medicago sativa L.)cultivars from 2013 to 2016.The results showed that the top three cultivars with the highest annual hay yield were Zhongmu No.3(14423 kg/hm2),Zhongmu No.2(13706 kg/hm2)and WL712 HQ(13144 kg/hm2).The yields of different harvests were significantly different(P〈 0.05),and the yield of first harvest was the highest,accounting for 38% of annual yield,and the fourth was the lowest.The top two cultivars with the highest yield of first harvest were Zhongmu No.3 and Zhongmu No.2,which also got the highest annual yields.The association coefficient between the first harvest and annual yield was the highest.The four-years' results showed that Zhongmu No.3 and Zhongmu No.2 were suitable to be cultivated for hay production in Hebei area and the three imported cultivars,WL712 HQ,WL903 HQ and MagnumVI also had excellent performance in hay production.
