| 摘 要： | 在雁门关地区,以28个紫花苜蓿不同品种作为研究对象,连续两年观测其再生速度、叶茎比、株高和干草产量,并利用近红外光谱(NIRS)技术对8个营养性状指标进行测定分析,并采用灰色关联度分析方法进行综合评价。结果表明:1)“阿迪娜”生长速度在2015和2016年均表现为最高,分别为2.78和3.19 cm·d-1;“WL363HQ”叶茎比在2015和2016年均表现为最高,分别为0.84和0.97;2) “WL298HQ” 在2015年的株高表现为最高(54.90 cm),“巨能7号”在2016年的株高表现为最高(84.27 cm);“鲁苜2号” 在2015年的干草产量表现最高,为6961.81 kg·hm-2,“巨能7号” 在2016年的干草产量表现最高,为8587.63 kg·hm-2;3)各品种的营养成分分析结果显示,“维多利亚”的粗蛋白含量最高,占干物质的26.80%;“维多利亚”的粗灰分和粗脂肪含量均表现为最高(分别为10.20%和 2.34%);“肇东”的干物质含量最高,达到94.55%;“康赛”的中性洗涤纤维含量和酸性洗涤纤维含量均最低,分别为27.18%和33.31%;“雷达克之星”的瘤胃非降解蛋白含量最高(22.27%);“康赛”的干物质体外消化率最高(79.93%)。通过灰色关联度综合分析显示,“维多利亚”、“康赛”、“WL298HQ”、“SK3010”、“巨能7号”5个品种的综合表现最优异,在雁门关地区具有较高的推广利用价值。

| Abstract: | Twenty-eight alfalfa (Medicago sativa) varieties were studied in Yanmenguan,Shanxi province.The growth rate,leaf ∶ stem ratio,plant height and hay yield were measured by conventional methods in two consecutive years.In addition,herbage nutritional qualities were measured by near infrared reflectance spectroscopy.Key results were:1) The growth rate of M.sativa cv.Adrendin were the highest at 2.78 and 3.19 cm · d-1 in 2015 and 2016 respectively.The leaf ∶ stem ratio of M.sativa cv.WL363HQ was the highest at 0.84 and 0.97 in 2015 and 2016 respectively.2) The plant height of M.sativa cv.WL298HQ was the highest at 54.90 cm in 2015;The plant height of M.sativa cv.Magnum Ⅶ was the highest at 84.27 cm in 2016.The hay yield of M.sativa cv.Lumu No.2 was the highest at 6961.81 kg · hm-2 in 2015,and the hay yield of M.sativa cv.Magnum Ⅶ was the highest at 8587.63 kg · hm-2 in 2016.3) The crude protein,crude ash and ether extract of M.sativa cv.Victorian were the highest at 26.80％,10.20％ and 2.34％;The dry matter percent of Zhaodong was the highest at 94.55 ％;The acid detergent fiber and neutral detergent fiber of M.sativa cv.Concept were the lowest at 27.18％ and 33.31％,respectively.The rumen undegradable protein of M.sativa cv.Ladak was the highest at 22.27％.The dry matter digestibility of M.sativa cv.Concept was the high-est at 79.93％.In this evaluation,M.sativa cv.Victorian,M.sativa cv.Concept,M.sativa cv.WL298HQ,M.sativa cv.SK3010 and M.sativa cv.Magnum Ⅶ,outperformed other varieties,which indicates that these five varieties are suitable for use in the Yanmenguan region of Shanxi province. |
