According to the consolidation practice and the special characteristics of land in the saline area with high soil salt content and less nutrient content, this article selected salt separating material(A), the depth of the salt separating layer(B) and ameliorants(C) as factors to design a 3 factors by 3 level orthogonal variance experiment. The results showed that after soil improvement, the soil bulk density, pH value and salt content decreased significantly, and the content of available nitrogen, phosphorus and organic matter increased but a slight decline in available potassium. Compared with the control group, the soil properties, main nutrients, crop biomass and yield of the test groups were significantly improved, and the indicators were significantly different. The best improvement program is A₂B₂C₁, in which the slag and straw are selected as the salt separating material, and the depth of the salt separation is 60 cm and organic fertilizer can be used as ameliorants.
