Abstract: 【Objective】 Through the application of the technology and equipment of silt ridge deep breaking barrier in different types of soil, the change of soil salinity at different points before and after irrigation was studied, and the leaching and desalination effect of silt ridge deep breaking barrier technology on saline-alkali land was analyzed.【Methods】 Using the powder ridge deep-breaking equipment, the deep-breaking depth reached 110 cm and the spacing of deep-breaking reached 200 cm in the moderately or above saline-alkali land. Samples were taken before and after winter irrigation. The sampling points were horizontal spacing of 0, 30 and 90 cm, and the sampling depth was 0-30, 30-60 and 60-90 cm, respectively.【Results】 After the barrier was broken by the deep loosening of the bed, the soil desalination rate before and after winter irrigation was: the horizontal direction of the sand soil was 0 cm=78% > 60 cm = 34% > 90 cm = 31%, and the vertical direction was 60-90 cm = 69%> 0-30 cm = 43% > 30-60 cm= 32%. The horizontal direction of loam was 60 cm=22% > 0 cm = 20% > 90 cm = 7%, and the vertical direction was 0-30 cm = 30% >30-60 cm=12% > 60-90 cm = 6%. The horizontal direction of clay was 0 cm = 33% > 60 cm = 29% > 90 cm = 21%, and the vertical direction was 0-30 cm = 40% > 60-90 cm = 27% > 30-60 cm = 17%.【Conclusion】 The highest desalination efficiency was 48%, 28% for clay and 18% for loam. The desalination rate was 44%, 28% at 30 cm and 20% at 90 cm in the barrier area with deep bed loosening. At different depths, the surface desalination rate of 0-30 cm was 38%, that of 30-60 cm was 20%, and that of 60-90 cm was 34%. The effect of washing and desalting of soil can be effectively improved by loosening and breaking the barrier in the bed.
