研究通过对从外省区引入新疆的几个高丹草品种品质性状和鲜生物产量的相关分析表明:粗脂肪、粗纤维、中性洗涤纤维、酸性洗涤纤维与鲜生物产量呈一定的正相关,粗蛋白、粗脂肪与干物质含量呈一定的正相关。综合分析表明,甘露2号和先锋两个高丹草品种相对其他品种具有明显优势,其中甘露2号鲜生物产量76300 kg/hm2,干生物产量26500 kg/hm2,粗蛋白含量8.77%,粗脂肪含量1.57%,粗纤维含量30.53%;先锋鲜生物产量74 766.67 kg/hm2,干生物产量25395.43 kg/hm2,粗蛋白含量8.78%,粗脂肪含量1.42%,粗纤维含量33.88%。 Based on the analysis of the correlation between the quality traits and fresh biomass of several cultivars introduced into Xinjiang from other provinces, the results showed that the crude fat, crude fiber, neutral detergent fiber and acid detergent fiber had certain positive correlation with the fresh biomass, Crude protein, crude fat and dry matter content showed a certain positive correlation. Comprehensive analysis showed that the two cultivars of Manlu 2 and Pioneer had obvious advantages compared with other cultivars. Among them, the yield of fresh produce of nectar 2 was 76300 kg / hm2, dry biomass was 26500 kg / hm2, crude protein content was 8.77%, crude fat Pioneer fresh biomass was 74 766.67 kg / hm2, dry biomass was 25395.43 kg / hm2, crude protein content was 8.78%, crude fat content was 1.42% and crude fiber content was 33.88%.
