摘　　要：以番茄品种“妞内姆1618”为试材,利用5个不同浓度的咸水(2、3、5、7、9 g·L^(-1)),以淡水(0.3 g·L^(-1))为对照,分别在番茄前期、中期、后期进行滴灌,研究不同时期咸水灌溉对番茄产量及品质指标的影响,以期为盐碱地设施番茄咸水灌溉制度提供参考依据。结果表明:前期≤5 g·L^(-1)咸水滴灌,产量及单果质量较对照降低不明显,但7、9 g·L^(-1)处理均达显著水平,而后期≤9 g·L^(-1)各咸水处理较对照差异均不显著,但却使中期单果质量显著降低;咸水滴灌提高了前期、中期的维生素C及有机酸含量,但却使果实后期的维生素C含量降低,使前期、后期果实硬度增加,且均提高了果实可溶性固形物含量。在土壤含盐量低于0.3%的滨海盐碱区,根据番茄不同时期进行适宜浓度咸水滴灌,能够达到保产提质目的。Tomato variety‘Nunem 1618’was used as test material,and 6 different concentrations of salt water(0.3,2,3,5,7,9 g·L^(-1))drip irrigation were carried out during the earier,middle,and later periods of tomatoes,the influence of salt water irrigation on tomato yield and quality in different periods were stuided,in order to provide a data support for the salt water irrigation system of tomatoes in saline-alkali land facilities.The results showed that using≤5 g·L^(-1) salt water drip irrigation during the earlier period,tomato yield and single fruit weight were not significantly reduced compared with the control,but the 7,9 g·L^(-1) treatments reached significant levels.There were no significant difference between the treatments of≤9 g·L^(-1) salt water drip irrigation at the later period compared with the control,but the single fruit weight was significantly reduced during the middle period.The salt water drip irrigation increased the vitamin C and organic acid content in the earlier and middle periods,but reduced the vitamin C content in the later period,and the hardness of the fruit increased in the earlier and later periods.The soluble solids content of the fruit increased of each treatment.According to the different periods of the tomato,the proper concentration of salt water drip irrigation could be used to achieve the purpose of maintaining yield and improving quality in coastal saline-alkali areas where the soil salt content was less than 0.3%.
