Comparative study on production performance and nutritional quality of five varieties of Sorghum×Sudan grass in Xing'an League

为筛选出适宜兴安盟地区种植、推广的高丹草品种。试验于兴安盟地区种植5个不同高丹草品种,对其生产性能及营养品质进行比较分析,采用灰色关联理论综合考量并评价兴安盟地区种植的5个高丹草品种。结果显示,标兵渔草的干草产量、鲜草产量优于其他品种,粗蛋白含量显著高于其他品种(P<0.05)。相比其他4个品种,标兵渔草的适口性更好,更容易被家畜采食并消化。兴安盟地区种植的5个高丹草品种排名依次为标兵渔草>海迪>杰宝>黑贝>超级糖王。研究表明,标兵渔草更适宜在兴安盟地区种植、推广。

In order to screen out the varieties suitable for planting and promotion in the Xing'an League,five different varieties of Sorghum×Sudan grass were planted in the Xing'an League,their production performance and nutritional quality were compared and analyzed,and the gray correlation theory was used to comprehensively consider and evaluate the five varieties of Sorghum×Sudan grass.The results showed that the hay yield and fresh grass yield of Standard Fishing Grass were better than those of other varieties,and the crude protein content was significantly higher than that of other varieties(P<0.05).Compared with the other four varieties,Standard Fishing Grass had better palatability and was easier to be eaten and digested by livestock.The five different varieties of Sorghum×Sudan grass planted in the Xing'an League were ranked as Standard Fishing Grass>Haidi>Jie Bao>Black Bay>Super Sugar King.The results showed that Standard Fishing Grass was more suitable for planting and promotion in the Xing'an League.
