Embodiment 1
[0031] Take soil samples from the plow layer (0-20cm) in the light clay alkalized paddy soil area to be improved, and analyze the mechanical composition after air-drying (see Table 1), and the soil bulk density is 1.36g / cm 3 . Screen the iron tailings to retain physical sand particles (0.01mm≤particle size<1mm). Mix the physical sand with 30% sulfuric acid solution at a soil-water mass ratio of 1:5, let it stand for 48 hours, and air-dry it for later use. At this time, the pH of the acidified iron tail mineral physical sand is 2.34. Analyze the mechanical composition of iron tail mineral rational sand before and after acidification, and determine the specific content of silt (0.01mm≤particle size<0.05mm) and sand (0.05mm≤particle size<1mm) in the physical sand. The specific results are shown in the table 2 and Table 3.

Embodiment 2
[0046] Take soil samples from the plow layer (0-20cm) in the light clay alkalized paddy soil area to be improved, the mechanical composition is shown in Table 6, and the soil bulk density is 1.36g / cm 3 . Screen the iron tailings to retain physical sand particles (0.01mm≤particle size<1mm). The physical sand and sulfuric acid solution with a mass concentration of 30% were evenly mixed according to the mass soil-water ratio of 1:5, and left to culture for 48 hours, and the pH of the acidified iron tail mineral physical sand was measured to be 2.12. See Table 2 and Table 7 for the mechanical composition of iron tailings (0.01mm≤particle size<1mm) before and after acidification.

Embodiment 3
[0058] Take soil samples from the plow layer (0-20cm) in the light clay alkalized paddy soil area to be improved, the mechanical composition is shown in Table 10, and the soil bulk density is 1.37g / cm 3 . Screen the iron tailings to retain physical sand particles (0.01mm≤particle size<1mm). Then, the physical sand of the iron tailings was mixed evenly with the hydrolyzed polymaleic anhydride solution with a solid content of 48%, left to culture for 48 hours, and then air-dried for later use. At this time, the pH of the acidified iron tailings mineral physical sands was measured to be 2.17. See Table 2 and Table 11 for the mechanical composition of iron tailings (0.01mm≤particle size<1mm) before and after acidification.
