日光温室越冬茬东西垄向栽培鲜食番茄品种适应性评价OA

To enhance the mechanization level of vegetable production in solar greenhouses and to screen suitable fresh tomato varieties for mechanized cultivation on east-west ridges,this study systematically investigated 20 indicators,including leaf phenotypic traits,fruit quality attributes,and spatial yield distribution,across 14 tomato varieties grown under an overwintering cultivation system in Ningxia.The Analytic Hierarchy Process(AHP)was used to determine the weighting of each evaluation indicator,and the Distance-based Technique for Order Preference by Similarity to Ideal Solution(DTOPSIS)was employed for comprehensive adaptability assessment of varietal adaptability.The results showed that under the mechanized cultivation mode,the difference in fruit set number between the southernmost and northernmost cultivation rows ranged from 23.07％to 116.00％among varieties,with'Provence'(PL)showing the smallest difference.The yield difference between these rows ranged from 7.93％to 23.42％,with'Jingfan 308'(JF 8)exhibiting the smallest yield difference and demonstrating the best adaptability to the east-west ridge cultivation.AHP weighting analysis revealed that yield,soluble solids content,lycopene content,single fruit weight,sugar-acid ratio,and vitamin C content were the core indicators for evaluating tomato varieties suitable for mechanized cultivation,accounting for a dominant cumulative weight.The comprehensive ranking based on the DTOPSIS method placed the large-fruited varieties'PL'and'Saixishi 5'(SX 5)in the top two positions.'PL'showed uniform yield distribution under the east-west ridge cultivation mode,while'SX 5'exhibited high yield performance.The medium-fruited varieties'Yashu 12'(YS 12)and'Jingfan 309'(JF 9)ranked third and fourth,respectively,offering a favorable combination of palatability and relatively high yield.Based on a comprehensive analysis of fruit setting performance,yields,and quality across the 14 tomato varieties,'PL','SX 5','YS 12',and'JF 9'are recommended as suitable fresh tomato varieties for mechanized cultivation on east-west ridges in solar greenhouses in the Ningxia region.
