Assessment on the Coupling Effects of Drip Irrigation and Se-Enriched Organic Fertilization in Tomato Based on Improved Entropy Weight Coefficient Model
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%.
