Abstract: 【Objective】 In order to investigate the effects of different magnetized water quality and electrolytic water drip irrigation on salinity of saline-alkali soil. 【Methods】 The test soil was taken from Company 6 of the 121st Regiment, and soil column infiltration test was carried out. The effects of brackish water, magnetized brackish water, magnetized channel water, channel water and electrolytic water drip irrigation on total salt content, desalting rate, soil salt ions and soil SAR were compared and analyzed. 【Results】 The results showed that the average total salt content of soil profile was T₁>T₂>CK>T₃>T₄. The total salt content of magnetized brackish water irrigation treatment was significantly lower than that of brackish water irrigation treatment at soil depth of 30-40 cm and deep soil depth, and the total salt content of soil under magnetized channel water irrigation treatment was significantly lower than that under channel water irrigation treatment. The average desalting rate of the desalting area in the soil profile of each treatment was compared as T₄>T₃>T₂>CK>T₁, and the desalting rate reached 51.8%-59.36%. Compared with the control treatment, the average desalting rate of soil profile desalting area in brackish water irrigation treatment decreased by 2.18%, magnetized brackish water treatment increased by 7.2%, magnetized channel water treatment increased by 8.99%, and electrolytic water treatment increased by 13.25%. The amount of Ca²⁺ in soil was increased by 72.59% compared with that before drip irrigation. At the same time, the contents of Cl^-, Na⁺ and HCO₃^- were decreased by 92.23%, 67.49% and 30.84%. Electrolytic water irrigation is beneficial to SO₄^2-leaching and desalting of soil profile, and the desalting rate is 34.09%. Irrigation treatment of magnetized channel water significantly reduced soil SAR at 0-50 cm depth. 【Conclusion】 With magnetized water irrigation treatment is superior to non-magnetized water irrigation treatment in reducing the average total salt content of soil and increasing the desalting rate of soil, and electrolytic water irrigation treatment is the best. Electrolytic water and magnetized water irrigation are beneficial to soil salt and harmful salt ions leaching and desalting.
