摘　　要：为解决酒泉市土地沙化,增加油料产能,筛选出甘肃河西荒漠区生态适应性强的油莎豆新品种,2023年对引进的农安早苗、农安晚苗、海南油莎豆、河北油莎豆及内蒙油莎豆5个油莎豆品种在酒泉市边际沙地进行了引种适应性试验。结果表明,5个油莎豆品种在酒泉市肃州区种植均可正常成熟,具有较好的适应性;块茎营养成分基本一致,均属于高淀粉材料,且粗蛋白与粗脂肪含量较高,油酸含量674.5~708.0g/kg;块茎产量6850.35~7312.8kg/hm^(2),机械化种植收入31725.95~34963.10元/hm^(2)。综合生态适应性表现,5个参试品种均适合在酒泉市及荒漠化生态区域大面积推广种植。In order to address the land desertification in Jiuquan City and increase oil plants production capacity,screening for new varieties of Cyperus esculentus with strong ecological adaptability in the arid desert area of Hexi,Gansu Province was conducted.In 2023,5 varieties of Cyperus esculentus including Nongan early seedling,Nongan late seedling,Hainan Cyperus esculentus,Hebei Cyperus esculentus and Inner Mongolia Cyperus esculentus underwent adaptability trials in marginal sandy areas near Jiuquan City.The results indicated that the 5 varieties of Cyperus esculentus exhibited generally consistent performance during the growth period in the Suzhou District of Jiuquan City,demonstrating commend ableadapt ability.The nutritional components of the tubers from the five trial varieties were largely similar,characterized by high starch content,elevated levels of crude protein,and ether extract with oleic acid content ranging between 674.5 to 708.0 g/kg.Tuber yields for the five trial varieties ranged from 6850.35 to 7312.8 kg/ha,with corresponding incomes from mechanized plantingranging from 31725.95 to 34963.10 Yuan/ha.The comprehensive ecological adaptability showed that the 5 tested varieties were suitable for large-scale popularization and planting in Jiuquan City and desertification areas.
