摘　　要：为筛选出适宜宁南山区种植的优质饲草谷子品种,试验从国内引进18个育成谷子品种,采用随机区组设计,对供试谷子品种测定及分析其生产性能、农艺性状、营养品质等指标,通过相对饲喂价值和粗饲料分级指数评价其饲用价值,最后采用灰色关联度法和聚类分析对18个谷子品种各性状指标进行综合评价。结果显示:蒙草谷1号、冀草谷1号、黄苗草谷子6-7号和陇鉴2129在灌浆初期和成熟期的鲜草产量和干草产量均较高,可作为高产草量饲草谷子品种进行引种;陇谷13号和黄苗草谷子6-7成熟期籽粒产量和草产量均处于中等偏上水平,可作为粮饲兼用型饲草谷子资源;陇鉴2129和黄苗草谷子6-7茎叶比低于其他饲草谷子,可作为叶量丰富型饲草谷子资源;绿苗草谷子181-10、陇鉴2129、赤草6号株高高于其他饲草谷子,可作为高秆饲草谷子资源;大同27号、大同39号和晋谷33号CP含量较高,RFV值和GI值处于中上水平,可作为高饲喂价值的饲草谷子资源。灰色关联度及加权分析显示,在宁南山区,陇鉴2129的综合表现最好,大同36号次之,蒙草谷1号、大同40号、黄苗草谷子6-7、冀草谷1号等几个饲草谷子处于中等偏上水平。研究表明,陇鉴2129、大同36号、蒙草谷1号、大同40、黄苗草谷子6-7、冀草谷1号可作为优质饲草谷子品种在宁南山区引种种植。In order to select high quality forage millet varieties suitable for planting in the south mountain areas of Ningxia,18 millet varieties were introduced from other scientific research institutions in China,the production performance,agronomic traits,and nutritional quality of millet varieties were measured and analyzed,and their feeding value was evaluated by relative feeding value and coarse feed grading index,then,the comprehensive evaluation of 18foxtail millet varieties was carried out by means of grey relational grade method and cluster analysis.The results showed that the fresh and dry grass yields of Mengcaogu 1,jicaogu 1,Huangmiaocaoguzi 6-7 and longjian 2129 were better at the early and mature stages of grain filling,longgu 13 and Huangmiaocaoguzi 6-7 are both at the middle and upper level of grain yield and grass yield at mature stage,which are forage foxtail millet resources for both grain and forage Longjian 2129 and Huangmiaocaoguzi 6-7 had lower stem-leaf ratio than other forage millet,which could be used as forage millet resources with abundant leaf.The plant height of Lvmiaocaoguzi181-10,longjian 2129 and Chicao 6 was higher than that of other forage foxtail millet,which could be used as high-stalk forage millet resources.Datong 27,Datong 39 and Jingu 33 had high CP content,and their RFV and GI values were in the upper middle level,which could be used as forage grain resources with high feeding value.Grey correlation degree and weighted analysis showed that longjian 2129 had the best overall performance,followed by Datong 36,mengcaogu 1,Datong 40,Huangmiaocaoguzi 6-7,Jicaogu 1 and other forage grass millet are in the upper middle level in the south mountain areas of Ningxia.The study indicates that the longjian 2129,Datong 36,Mengcaogu 1,Datong 40,Huangmiaocaoguzi 6-7 and Jicaogu 1 are suitable for introduction and cultivation as high quality forage millet varieties.
