| 摘 要： | 以宁夏盐池县本地苜蓿XM及宁夏益科农业科技有限公司引进的15个美国紫花苜蓿品种为研究对象,综合考虑生育期、株高、密度、产草量、茎叶比、越冬率等指标,开展苜蓿引种适应性研究.结果表明,以本地种XM为对照,15个外引种紫花苜蓿在生长发育特性上存在显著差异.其中,以品种ZHM,E3006,D4,D2表现较优,其返青早,青绿期长,鲜草产量分别是对照的1.52,1.45,1.28,1.25倍,干草产量分别是对照的1.46,1.25,1.22,1.19倍,且抗旱性强,品质优良,适宜在宁夏盐池县等中部干旱带大面积推广应用. |

| Abstract: | In order to study the adaptability of American high quality alfalfa, which were introduced by Ningxia Yike agricultural technology Co. , Ltd. , the compared experiment among the introduced alfalfa varieties and local variety in Yanchi of Ningxia was conducted, and the growth stages, plant height, density, yield and stem-leaf ratio of each alfalfa varieties were tested. The results showed that the fifteen different introduced alfalfa varieties were significant differences in the growth and development characters, among of them, ZHM, E3006, D4 and D2 are better than the others. Compared with local variety, their turning green were earlier, green period were longer and the fresh yield increased 1.52,1.45,1.28,1.25 times, the dry yield increased 1.46,1.25,1.22,1.19 times, respectively. The high quality varieties showed stronger dry resistance and they are suitable for popularization and application in middle arid belt of Ningxia, such as Yanchi county. |
