| 摘 要： | 为探讨不同紫花苜蓿(Medicago sativa)在伊犁河谷的生产性能,本研究选择了10个紫花苜蓿品种作为研究材料,对其物候期、株高、草产量、叶茎比和干鲜比等生产性能指标进行分析评价,结果表明,10个苜蓿材料在试验区均能完成生活史,生长节律变化比较一致,在第2年进入高生长期；并随着刈割次数的增加,植株高度和产草量逐渐降低。在生长第2年,可刈割3茬,冰驰、骑士、勇士、三得利、标靶的干草产量均在11 500 kg?hm-2以上,具有植株高大、产草量高、干鲜比高等特点,综合表现较好,适宜推广种植；拉迪诺、5010、FY310、岩石,各项指标居中,可作为补充候选品种推广种植；敖汉在试验区表现较差,不适宜在本地区推广。

Production Performance of 10 Alfalfa Varieties in Ili Valley |
| |
| Abstract: | Aiming at the production performance of alfalfa in Ili Valley, ten alfalfa varieties were selected as materials, the phenological period, plant height, grass yield, leaf-stem ratio and dry-fresh ratio were analyzed and evaluated. The results showed that the ten alfalfa varieties were able to complete their life history in the test area, the growth rhythm change was consistent, the high-yield period appeared in the second year; the plant height and grass yield decreased gradually with the increase of cutting times. In the second year, after three cutting times, the dry yields of‘Bingchi’,‘Cavaliers’,‘Warrior’,‘Sanditi’,‘Barricade’were all above 11500 kg/hm2, and they had the characteristics of high plant, high yield and high dry- fresh ratio, the comprehensive performance was better, and they were suitable for popularizing. The indexes of‘Ladino’, ‘5010’,‘FY310’and‘Rugged’were medium, which could be used as supplementary candidates for promotion;‘Aohan’showed worse performance in the test area, which was not suitable for promotion in Ili Valley. |
