Selenium (Se) is an essential micronutrient for human beings and plants are the current main sources of Se element in Asian diet. Therefore a feasible way to increase people’s Se intake is to increase Se content in plants. In this paper, we focus on how the tomato (Solanum Lycopersicum) yield and quality are influenced by the effect of irrigation amount, Se-enriched and high-calcium organic fertilizer and compound fertilizer amount respectively. The results from a two-year experiment show that the combination of Se-enriched organic fertilizer and compound fertilizer can significantly increase the tomato yield comparing with the use of NPK organic or compound fertilizer. It is also shown that by applying more Se-enriched and high-calcium organic fertilizer the contents of Se, Lycopene, Vitamin C (Vc) and soluble sugar in tomato fruit can be increased considerably. It was found that the highest Se content was achieved using 100% Se-enriched organic fertilizer combined with irrigation at 100% in 2016 and 100% Se-enriched organic fertilizer with irrigation at 80% in 2017. Deficit irrigation (80%) can help to increase Water Use Efficiency (WUE) and the Se and VC contents in tomato yield. Therefore in order to improve the Se-enriched tomato yield and quality, it is suggested to apply 100% Se-enriched organic fertilizer and adopt the deficit irrigation at 80%.

硒是人类必需的微量元素，植物是目前亚洲饮食中硒的主要来源。因此，增加人们的硒摄入量的一种可行方法是增加植物中的硒含量。在本文中，我们将重点放在番茄（Solanum Lycopersicum）上。产量和品质分别受灌溉量，富硒有机肥和高钙有机肥和复合肥用量的影响。一项为期两年的实验结果表明，与使用NPK有机或复合肥料相比，富硒有机肥料与复合肥料的组合可以显着提高番茄的产量。还表明，通过施用更多的富硒和高钙有机肥料，番茄果实中的硒，番茄红素，维生素C（Vc）和可溶性糖的含量可以显着增加。结果发现，2016年使用100％富硒有机肥与100％灌溉配合使用的硒含量最高，2017年使用100％富硒有机肥与80％灌溉配合使用的比例达到了最高硒含量。亏缺灌溉（80％）可以帮助提高番茄的水分利用效率（WUE）以及硒和VC含量。因此，为了提高富硒番茄的产量和品质，建议施用100％富硒有机肥，并采用80％的亏缺灌溉。
