摘　　要：采用完全随机实验设计,对新牧1号杂花苜蓿适宜浇水时期、浇水次数及浇水量进行研究,结果表明:不同浇水处理对提高新牧1号杂花苜蓿干草产量有一定的影响,各试验处理间表现出显著差异(P<0.05);浇水时期中以刈割前5天浇水增产效果最好,干草产量比对照提高25.67%以上,且浇水处理增大了苜蓿干草中茎杆比例;浇水次数可以提高干草品质,且以浇二水处理效果较好,产量比对照提高18.94%以上;浇水量中以1 130 m3/hm2的处理干草产量最高,比对照提高24.92%。The studies on yield production of Medicago sativa. （L.）cv. Xinmu No. 1 were carried out about setting up proper irrigation period, times and amounts of water with completely random experiment design. The results showed： different irrigation treatment had a distinct effects on increasing the yield of alfalfa, and had a distinct difference among the treatments （P 〈 0.05）. Stalk proportion of alfalfa hay was increased by different treatment of irrigation period, and the yield was the highest with treatment of irriga- ting before alfalfa had been cut for about five days, the yield of hay was increased by 25.67% than CK. Times of irrigation could increase quality of alfalfa hay. Compared with CK, the yield of hay was highest with the treatment of irrigating with twice, was increased by 18.94% than CK. The yield of hay was the highest with the treatment of 1130 m^3/hm^2 in the amount of water,which was increased by 24.92% than CK.
