The study simulated how different irrigation and drainage methods affect soil salt movement. Results show that water-saving irrigation is similar to conventional irrigation in reducing soil salinity. Cutting irrigation water by 14.36% doesn't significantly impact salt-leaching efficiency. Continuous water-saving or conventional irrigation decreases soil salinity over time. Pipe drainage reduces salt accumulation compared to no drainage. The research supports water-saving irrigation and emphasizes the need for effective drainage to manage soil salinity in the Yinbei irrigation district of Ningxia.
