摘　　要：本研究模拟大庆地区土壤环境配置混合盐碱溶液(Na_(2)CO_(3)∶NaHCO_(3)∶NaCl∶Na_(2)SO_(4)=3∶57∶25∶15),以100 mmol/L、200 mmol/L、250 mmol/L和260 mmol/L等4个浓度对42个甜瓜品种进行处理,研究盐碱胁迫对甜瓜种子发芽率、发芽受损率、发芽势、发芽指数等指标的影响,并对供试甜瓜品种进行耐盐碱综合评价分析。结果表明,供试品种在250 mmol/L的混合盐碱胁迫下出现萌发转折,函数分析显示,甜如蜜、懒瓜王、嘎嘎甜为耐盐碱品种;甜脆花皮(烧瓜)、Top mark、MS-5为盐碱敏感型品种。A mixed saline-alkali solution(NaCO_(3)∶NaHCO_(3)∶NaCl∶Na_(2)SO_(4)=3∶57∶25∶15) was configured to simulate the soil environment in Daqing area, with four concentrations of 100 mmol/L, 200 mmol/L, 250 mmol/L and 260 mmol/L as treatments for 42 melon varieties. The effect of salt-alkali stress on seed germination rate, germination damage rate, germination potential, germination index and other indicators were studied. The comprehensive evaluation and analysis of salt-alkali tolerance of the tested melon varieties were carried out. The results showed that the test varieties had a germination turning point in the 250 mmol/L mixed saline-alkali solution. According to the function analysis, Sweet Rumi, Lazy Melon King, and Gagatian were the salt-tolerant varieties;Sweet and Crispy Flower Peel(Sweet Melon), Top mark, MS-5 were a salt-alkali-sensitive melon varieties.
