Micro-nanobubble oxygenation irrigation ameliorates saline-alkali soil properties, cotton physiology, and yield under different salt stress levels.

3.3 Soil salt ions To investigate the effects of different treatments on soil ion content in saline cotton fields ( Tables 2 – 4 ), the results demonstrated that salt concentration, irrigation method, and their interaction had highly significant effects ( P < 0.05) on the concentrations of Ca2 + , Mg2 + , K + , Na + , HCO 3 - , Cl - , and SO 4 2 - in the 0~20 cm soil layer.

3 Results 3.1 Soil salinity To investigate the effects of different irrigation treatments on soil salinity in saline cotton fields ( Figure 2 ), soil salinity in the top layer (0~20 cm) exhibited a gradual decrease across all eight treatments as the cotton growth period advanced, while an increasing trend was observed in the deeper soil layer (40~60 cm).
