|
摘要
本研究以里奥(Lotus corniculatus cv.Leo)、迈瑞伯(Lotus corniculatus cv.Mirabal)、佐治亚(Lotus corniculatus cv.Georgia)作为对照,对从俄罗斯引进的61份百脉根种质材料在西北绿洲进行种植试验,依据营养指标变异分析和灰色关联度法进行营养指标分析和综合评价。结果表明,粗蛋白变异最明显,变异系数最大,为13.569%;磷含量、钙含量和相对饲喂价值的变异明显,变异系数较大,分别为13.187%、12.044%、11.537%;酸性洗涤纤维、粗脂肪和中性洗涤纤维的变异系数分别为9.763%、8.559%、8.533%,变异较明显;干物质的变异最不明显,仅为0.609%。根据灰色关联度加权分析,其中Zxy08p-4687(γi=0.748)、Zxy09p-5647(γi=0.733)、Zxy09p-6485(γi=0.713),综合营养价值高;营养价值较高的百脉根材料有10份(0.604≤γi≤0.682),分别为Zxy08p-5070、Zxy09p-5583、Zxy08p-4892、Zxy09p-5642、Zxy06p-1775、Zxy09p-5591、Zxy08p-4916、Zxy09p-5809、Zxy08p-4645、Zxy09p-5694;营养价值中等的材料有27份及对照材料佐治亚(0.505≤γi≤0.587),占44.262%,包含Zxy09p-5591、Zxy08p-4768、Zxy08p-4589、Zxy06p-2666、Zxy06p-2663等;营养价值较差的材料有21份及对照材料迈瑞伯、里奥(0.423≤γi≤0.499),占34.426%,比如Zxy06p-2376、Zxy09p-6358、Zxy08p-5393、Zxy08p-4528、Zxy09p-6300等。
The nutritive value of 61lotus(Lotus corniculatus)germplasm material introduced from Russia were comprehensively evaluated in this study in the oasis in Northwest China based on the variability analysis and grey relational grade analysis.Leo(Lotus corniculatus CV.Leo),Mirabal(L.corniculatus cv.Mirabal)and Georgia(L.corniculatus cv.Georgia)were used as control materials.Our results revealed the following:Crude protein content varied significantly(13.569%),variation coefficients of phosphorus,calcium,and relative feed value were 13.187%,12.044%,and 11.537%,respectively.The coefficient of variation of acid detergent fiber,ether extract and neutral detergent fiber were 9.763%,8.559%,and 8.533%,respectively.Dry matter variation was small and insignificant(0.609%).According to the grey relational degree weighted analysis,the weighted grey correlative degree of Zxy08p-4687,Zxy09p-5647,Zxy09p-6485 was 0.748,0.733,0.713,respectively,which had the highest nutritive value.The higher nutritive value of germplasm materials(0.604≤γ≤0.682)included were Zxy08p-5070,Zxy09p-5583,Zxy08p-4892,Zxy09p-5642,Zxy06p-1775,Zxy09p-5591,Zxy08p-4916,Zxy09p-5809,Zxy08p-4645,and Zxy09p-5694.Georgia(0.505≤γi≤0.587),and 27 germplasm accessions had intermediate nutritive value,which indicated that of the total germplasm accessions only44.262%,including Zxy09p-5591,Zxy08p-4768,Zxy08p-4589,Zxy06p-2666,Zxy06p-2663.The low nutritive value group contained 21 germplasm accessions,Mirabal,and Leo(0.423≤γi≤0.499),which were about34.426% of the total,including,Zxy06p-2376,Zxy09p-6358,Zxy08p-5393,Zxy08p-4528,and Zxy09p-6300.
