Salt basking field improvement method

The invention discloses a salt basking field improvement method which comprises the following steps: S1, dividing a salt basking field into a plurality of square lands, arranging a salt discharging device around each square land, building a mechanical farming road around each square land, then leveling the land, and laying a degradable mulching film; s2, making a nutrient brick soil layer; and S3, laying the nutrient brick soil layer obtained in the step S2 on the degradable mulching film in the step S1 to obtain the improved sun-cured salt pan. Through the design of the multiple dark pressure ditches, land pressure reduction is not prone to salt return, heavy salt can be flushed and discharged through rainwater via the dark pressure ditches in rainy days, then the salt is discharged out of the field through the salt discharging device, and through the design of manufacturing the nutrient brick soil layer and laying the nutrient brick soil layer on the surface of the improved land, the salt content of the lan
