摘　　要：为了研究6种不同来源草木樨的生产性能与营养品质差异,试验选出适宜于新疆栽种的品种,采用大田测定及实验室测定方法,测定了不同来源草木樨生物特性、产量及营养成分,并通过计算粗饲料分级指数(GI值)对营养品质进行了综合评定。结果表明:MAL001(来自甘肃的白花草木樨)的全年干草产量最高,为11 500 kg/hm2,MOF001(来自甘肃的黄花草木樨)粗蛋白产量最高,为1 729.18 kg/hm2。6种草木樨全年干草产量高低顺序为MAL001(来自甘肃的白花草木樨)、MAL002(来自内蒙古的白花草木樨)、MOF003(来自宁夏的黄花草木樨)、MOF001(来自甘肃的黄花草木樨)、MOF002(来自吉林的黄花草木樨)、MIN001(来自江苏的印度草木樨),全年粗蛋白产量高低顺序为MOF001>MAL001>MAL002>MOF003>MOF002>MIN001。通过GI指数对6种草木樨的营养品质进行综合比较,营养价值高低为MOF002>MIN001>MAL001>MOF001>MAL002>MOF003。根据综合营养品质和生产性能进行评定,MAL001最适宜在阿拉尔市栽培,其次为MAL002。To study the differences of productive performance and nutritional quality among 6 Melilotus varieties from different habitats, the varieties that are suitable for planting in Xinjiang were selected. The laboratory and field experiments were conducted to the biological characteristics, yields, and nutritional contents of the different Melilotus varieties; the overall evaluation for the nutritional quality was also conducted by calcu- lating the graded index （GI） of roughage. The result showed that the top cultivars with the highest annual hay yield and annual crude protein （CP） yield were MAL001 （M. albus from Gansu, 11500 kg/hm^2） and MOF001 （M. officinalis from Gansu, 1 729.18 kg/hm^2）, respectively. The annual hay yields of 6 Melilotus varieties in descending order were as follows： MAL001 （M. albus from Gansu）, MAL002 （M. albus from Inner Mongolia）, MOF003 （ M. offtcinalis from Ningxia）, MOF001 （ M. oflicinalis from Gansu）, MOF002 （ M. o.fftcinalis from Jilin）, and MIN001 （Melilotus indicus from Jiangsu）. The annual CP yields of 6 Melilotus in descending order were as follows： MOF001, MAL001, MAL002, MOF003, MOF002 ,and MIN001. The nutritional quality of 6 Melilotus varieties was comprehensively compared based on the grading indexes, and the nutritional values of 6 Melilotus varieties in descending order were as follows： MOF002, MIN001, MAL001, MOF001, MAL002, and MOF003. Based on the overall evaluation for nutritional quality and productive performance, the results indicate that MAL001 is the most appropriate cuhivar in Alar,followed by MAL002.
