摘　　要：筛选盐碱地适生大豆资源对充分利用盐碱地、提高作物产能、保障国家粮食安全具有重要意义。基于此,本研究采用盐碱地直播方法对144份大豆品种进行了苗期、全生育期耐盐鉴定。结果表明,“陕豆24”、“中作14”、“圣育24”等20份品种苗期耐盐性较好,“邯18-403”、“华豆45”、“华豆40”等34份品种全生育期耐盐性较好。最后采用隶属函数法对苗期和全生育期的评价指标进行综合分析,获得20份盐碱地耐盐性综合表现较好的品种,尤其是“圣育24”、“陕豆24”、“中作12”、“圣豆147”、“菏19-64”、“陇豆655-2”、“冀21YG105”等7份品种。本研究结果对盐碱地推广适生大豆品种具有参考价值。Screening suitable soybean resources for saline-alkali land is of great significance for fully utilizing saline-alkali land, improving crop productivity, and ensuring national food security. Based on this, this study identified the salt tolerance of 144 soybean varieties during the seedling stage and the whole growth period through direct sowing in the saline-alkali land. Results showed that 20 varie-ties including “Shandou 24”, “Zhongzuo 14”, and “Shengyu 24” performed better salt tolerance dur-ing the seedling stage, while 34 varieties including “Han 18-403”, “Huadou 45”, and “Huadou 40” performed well during the whole growth period. Finally, the membership function analysis was used to process all evaluation indexes in the seedling stage and the whole growth period, and found 20 varieties showing better performance in comprehensive salt tolerance, especially the 7 varieties of “Shengyu 24”, “Shandou 24”, “Zhongzuo 12”, “Shengdou 147”, “He 19-64”, “Longdou 655-2”, and “Ji 21YG105”. The research results provided a reference for promoting suitable soybean varieties in saline-alkali land.
