摘　　要：对2020年引进的6个耐机械损伤菠菜品种(Sp001,Sp002,Sp021,Sp031,Sp061和皇10-3)在设施大棚进行了鉴定与比较实验,分析了6个菠菜品种的植物学性状、营养指标和质构特性的差异.结果表明:不同品种之间的基本植物学性状无显著差异,但不同品种间叶片硬度、叶片长/叶柄长、抗坏血酸和硝态氮含量等存在显著差异,变异率分布在10.37%~19.16%.综合比较分析得出结论:Sp031的叶厚和叶片硬度最高,叶片长/叶柄长之比最大,植物学性状最为优良,综合品质性状表现良好,为6个品种中最适宜机械化收获的品种.In this study,six spinach(Spinacia oleracea L.)varieties(Sp001,Sp002,Sp021,Sp031,Sp061 and Huang 10-3)introduced in 2020 were identified and comparing tested in the greenhouse.The differences of their botanical characters,nutritional indexes and texture characteristics among six spinach varieties were analyzed.There was no significant difference in basic botanical characters among different varieties.There were significant differences in the contents of cellulose,ascorbic acid,carotenoid,soluble sugar,soluble protein and nitrate nitrogen among different varieties,and the coefficient of variation was 10.37%-19.16%.The conclusion of comprehensive comparative analysis is that Sp031 has the highest leaf thickness and leaf hardness,the highest ratio of leaf length and petiol length the best botanical characters,good comprehensive quality characters.Thus Sp031 is the most suitable variety for mechanized harvest among the 6 varieties.
