中文摘要	为了研究寒旱荒漠地区紫花苜蓿(Medicago sativa L.)适宜的灌水周期和灌水量,寻找合理的灌溉制度,对紫花苜蓿在浅埋式滴灌条件下开展了大田滴灌试验,采用双因素方差分析法,分析了灌水周期和灌水定额对不同生育阶段紫花苜蓿株高、茎粗和干物质积累的影响。结果表明:灌水周期和灌水定额对不同生育阶段的紫花苜蓿株高、茎粗和干物质积累量影响程度各不相同,合理安排灌水周期和灌水定额可以达到节水增产的效果。寒旱荒漠地区紫花苜蓿全生育期适当的灌水总量约为6 450m~3·hm~(-2)。其中第一茬紫花苜蓿灌水约8次,灌水量约为3 075m~3·hm~(-2);第二茬紫花苜蓿灌水约10次,灌水量约3 375m~3·hm~(-2)。
英文摘要	To establish a reasonable irrigation system on Medicago sativa L that grown in the cold and arid area,we studied the suitable irrigation cycle and irrigation amount.The subsurface drip irrigation experiment of Medicago sativa L was carried out.The effects of irrigation cycle and irrigation amount on plant height,stem diameter and dry matter accumulation of M.sativa L at different growth stages were analyzed by ANOVA and SPSS 18.0.The results showed that the effects of irrigation time and irrigation amount on the plant height,stem diameter and dry matter accumulation of M.sativa L were different at different growth stages.It can achieve the effect of saving water and increasing production could be realized through a reasonable arrangement of irrigation cycle and irrigation amount.The suitable irrigation amount was 6 450m~3·hm~2 in the whole growth period of Medicago sativa L in the cold and arid area.The first cutting irrigation times was about 8,and the total irrigation amount was 3 075m~3·hm~2.The second cutting irrigation times was about 10,and the total irrigation amount was 3 375m~3·hm~2.
