Abstract: Soil aeration and plastic film mulching have been reported to accelerate plant growth and increase fruit yield by improving the rhizosphere soil–air environment. The aim of this study was to investigate plant growth, fruit yield, irrigation water-use efficiency (IWUE) and fruit quality in response to a micro/nano-bubble aeration (MNBA) system and a subsurface artificial air layer aeration system (SAALA) under different treatments. The results indicated that both MNBA and SAALA positively influenced the plant dry weight, fruit yield, IWUE and fruit quality. In comparison with the no aeration treatment, the MNBA treatment increased the dry matter accumulation, fruit yield, IWUE, lycopene content and soluble protein content by 7.1%, 9.0%, 7.1%, 6.2% and 16.2%, respectively. Plastic film mulching (PFM) significantly improved the total dry weight, fruit yield and IWUE during both seasons. The increased yield in response to soil aeration during autumn was significantly greater than that during spring, and the yield increase in response to PFM was significantly greater in spring than in autumn. Moreover, the nutrition indices in response to both soil aeration and PFM were more significant during spring than autumn. Taking into account costs, efficiency and benefits, the optimal treatment was the MNBA and full (F) PFM combination.
