Abstract：Reduction in soil air permeability could result in an anaerobic root zoon, thereby detrimentally affect-ing plant growth and yield. To investigate the efficacy of irrigation with mixed nano-micro air bubbles in aerating soil and the consequent impact on growth, yield and fruit quality of tomato, we conducted plot experiments under different soil moistures in a greenhouse. The results showed that the growth rate of the plant height, stem diame-ter and leaf area of the tomato irrigated with the air bubbles was significantly faster than those under conventional irrigation at the seedling, flowering and fruit setting stages. Aerating irrigation with air bubbles improved tomato yield and water use efficiency compared with conventional irrigation. Moreover, it also led to early ripeness, a sig-nificant increase in the contents of VC, soluble solids and protein, but a decrease in the content of organic acids. Sugar-acid ratio under aerating and conventional irrigations was almost the same.
