中文摘要:

      [目的]本研究以引进的15个紫花苜蓿品种为研究对象，筛选出酒泉荒漠区粘土地适宜种植的紫花苜蓿品种，为大面积推广种植提供科学依据。[方法]通过分析不同品种在越冬率、干草产量、营养品质等方面的表现，应用灰色关联度分析法综合评价不同品种适应性及生产性能之间的差异。[结果]甘农3号、公农1号、赛特、WL363HQ、阿迪娜在越冬率、干草产量、营养品质等方面的综合表现好于其他品种。[结论]甘农3号、公农1号、赛特、WL363HQ、阿迪娜适合在酒泉荒漠区粘土地及相类似的气候土壤条件下推广种植。

英文摘要:

      [Objective] In order to provide a scientific basis for large-scale extension of cultivation， 15 introduced alfalfa varieties were used as the research objects to select suitable alfalfa varieties for planting in clay soil of Jiuquan desert area.[Method] The performance of 15 introduced alfalfa varieties in overwintering rate, hay yield and nutritional quality were analyzed in this study, grey relational grade analysis was used to evaluate the difference of adaptability and productive performance in different varieties. [Result] GanNong 3, GongNong 1, Sitel, WL363HQ, Adrenalin in winter rate, hay yield, nutritional quality and other aspects of the comprehensive performance were better than other varieties.[Conclusion] Gannong 3, Gongnong 1, Sitel, WL363HQ and Adrenalin were suitable to be planted in clay soil of Jiuquan and the area of similar climatic soil conditions.
