摘　　要：为促进旱区草业开发、畜牧业基地建设和生态农业发展,筛选出再生性强、产量水平高、WUE高的人工牧草品种,我们于2001—2002年研究了12个国内外紫花苜蓿品种再生草产量、再生草生长速度以及再生草水分利用效率。结果表明,所有引进种二茬草的再生速度都比当地品种会宁快,三茬草中大多数引进种再生速度比当地品种会宁快。所有引进种再生草的产量都高于当地品种会宁。阿尔冈金、苜蓿王、西香、西河、WL—323ML等品种再生草产量高,水分利用效率高,再生性强。In order to promote the development of grass industry in the drought-hit area, the construction of the animal husbandry base, and the development ecological agriculture, to select the species of artificial herb with high regeneration, high output and high WUE, the yield, the speed and the water use efficiency of re-growing hay of twelve alfalfa cultivars from domestic and aboard are studied in 2001 and 2002. The results showed that re-growing speed of all introductions in the 2nd harvest was higher than the local cultivar Hui'ning , most of introductions were higher than local cultivar in 3rd harvest. The yield of all introductions were higher than local cultivar Huining. Algoquin, Emperor, Cimmaron, Siriver, WL-323Ml have high re-growing hay yield, high WUE and strong regeneration.
