摘要

以焉耆盆地主栽的5个加工番茄品种为试材,选择富硒耕地(土壤硒含量0.4 mg/kg)和非富硒耕地(土壤硒含量未检出)为试验地点,采取随机区组试验,研究分析天然富硒土壤上不同加工番茄品种硒富集能力及品质,并进行综合性评价,以期筛选出适合当地种植的富硒能力较强的加工番茄品种.结果表明,富硒区不同加工番茄品种均达到富硒农产品标准,且属于天然富硒番茄.'屯河1943'、'屯河3501'、'屯河5501'硒富集能力强,生物富集系数依次为6.6%、6.6%、6.3%.天然富硒土壤上种植加工番茄可改善加工番茄品质,富硒区加工番茄番茄红素含量高于非富硒区,'屯河3501'、'屯河5501'番茄红素含量高于'屯河1015'、'屯河1943'、'屯河17';'屯河1943'、'屯河3501'、'屯河17'还原糖含量富硒区高于非富硒区;富硒区加工番茄总酸含量高于非富硒区,'屯河3501'总酸含量最高,'屯河1943'总酸含量次之,'屯河1015'总酸含量最低.通过隶属函数综合分析,'屯河3501'在天然富硒土壤上的综合表现最优,'屯河1943'次之.

Abstract

Five different tomato varieties were chosen as the experimental subjects in the Yanqi basin,and two types of cultivated land were selected as experimental sites,including selenium-enriched land with a selenium content of 0.4 mg/kg in the soil,and non-selenium-enriched land with no detectable selenium content.The objective of this study was to analyze and evaluate the selenium enrichment ability and quality of these tomato varieties in natural selenium-enriched soil,and to identify the varieties that were suitable for local cultivation.The findings would provide a theoretical foundation for the development of the selenium-enriched industry in the Yanqi basin.The results revealed that the processed tomato varieties in selenium-enriched areas met the standards for selenium-enriched agricultural products and were considered natural selenium-enriched tomatoes.The varieties'Tunhe 1943','Tunhe 3501',and'Tunhe 5501'exhibited strong selenium enrichment abilities,with bioconcentration factors of 6.6%,6.6%,and 6.3%,respectively.Planting processed tomatoes in natural selenium-enriched soil improved the quality of the tomatoes,as evidenced by higher lycopene content in the selenium-enriched areas compared to the non-selenium-enriched areas.Furthermore,'Tunhe 3501'and'Tunhe 5501'had higher lycopene content than'Tunhe 1015','Tunhe 1943'and'Tunhe 17'.In selenium-enriched areas,the reducing sugar content of'Tunhe 1943','Tunhe 3501',and'Tunhe 17'was higher than that in non-selenium-enriched areas.The total acid content of processed tomatoes in selenium-enriched areas was also higher than that in non-selenium-enriched areas.'Tunhe 3501'had the highest total acid content,followed by'Tunhe 1943',and'Tunhe 1015'had the lowest content.A comprehensive analysis of the membership function demonstrated that'Tunhe 3501'performed the best overall in natural selenium-enriched soil,followed by'Tunhe 1943'.
