摘要
引进15个不同秋眠级别的紫花苜蓿Medicago sativa品种,在郑州地区测定其生长第1年和第2年的鲜草产量、株高、叶茎比、营养成分等各项农艺性状指标,分析评价不同秋眠级别苜蓿品种的生产性能。结果表明:1)秋眠和半秋眠苜蓿的鲜草产量高于非秋眠苜蓿,每年刈割5次,所有品种第1茬>第2茬>第3茬>第4茬>第5茬。2)从产量和品质角度考虑,秋眠级数为3的苜蓿王(Alfaking)、WL-324和秋眠级数为5的射手(Archer)最适合中原地区。因此郑州地区在苜蓿的育种和引种工作中,应主要考虑秋眠和半秋眠的高产品种的培育与引进。
The study on production performance of 15 introduced alfalfa varieties with fall dormancy （FD） classes ranging from classes 2 to 9 was conducted by measuring the fresh matter yield, plant height, leaf to stem ratio and nutrient content in Zhengzhou in order to evaluate their agronomical traits. The results indicated that 1） the fresh forage yields of varieties from class 3 to class 5 were higher than those from class 6 to class 8, and as for, the fresh matter yield of different cuttings ranked from first to fifth while 5 cuttings were made in one year; 2） in consideration of yield and quality, the most suitable alfalfa varieties grown in Zhengzhou were Alfaking （FD3）, WL-324 and Archer （FDS）.
