摘　　要：采用盆钵垂直板法,研究了清水和雪水对紫花苜蓿在幼苗生长过程中的影响,对两组苜蓿幼苗的株高、根长、茎粗、物质积累等指标进行了对比分析。结果表明:雪水处理组的苜蓿幼苗生长状态明显优于清水处理组,发芽率较对照平均高出28.26%,株高、茎粗、干物质积累均显著高于对照(P<5%),根长与对照相比较无显著差异(P>5%),雪水对苜蓿幼苗生长具有显著促进效应。建议:在农业生产中,广泛应用雪水促进牧草饲料作物增产丰收,尤其雪水浸种对改善作物苗期的生长势效果明显。The paper have Separately studied the influnce of running water and snow melt water on alfalfa in seedling growth process, adopting the basin-port vertical slab method,and carries out a comparative analysis of two groups of alfalfa seedlings height, root length,stem diameter,matter accumulation of such indicators.To alfalfa seedlings growth state,results show that snow water treatment group obviously superior water treatment groups,high 28.26% than the average.Stem diameter,dry matter accumulation were significantly higher than controls（p5%）,compared with controls for root no significant difference（p5%）,snow melt water to alfalfa seedlings significantly promote effect.Suggestion： the wide applications on pasture feed will promote increasing harvest in the agricultural production,especially with snow smelt water soaked seeds,to improve crop seedling growth vigour influnce is obvious.
