【Abstract】 In this paper, 6 growth benefit indices of 14 local alfalfa (Medicago sativa L.) cultivars planted in Gansu province were studied. The differences between 14 cultivars were acquired through analysis of variance and multiple correlation method. The result showed that the growth benefit of alfalfa in Minqin, Yuzhong and Huanxian was better than that in other places of Gansu province under the same situation.更多还原
