A regulating method aims at the physical structure of a high-yield soil for summer corns, and belongs to the technical field of agricultural production. The regulating method of the invention is as follows: (1) deep ploughing (loose) before sowing: before the seeding of the previous crops before the summer corns, the soil is deeply ploughed (loose), the tilth is 30 to 35cm, the unit weight of a soil horizon of 0 to 20cm is 1.2 to 1.3g/cm3 by deep ploughing, the unit weight of the soil horizon of 20 to 40cm is 1.3 to 1.4g/cm3, and 15 kilograms of urea are fertilized per mu; and (2) ridging after sowing: before the seeding of the corns, wide row and narrow row seeding is required to be carried out, the space between the wide rows is 70 to 80cm, the space between the narrow rows is 40 to 50cm, during the jointing stage of the corns, cultivation, banking and ridging are carried out, ditches are opened in the wide rows of the corns, the narrow rows are banked and ridged, the ridge height is 15 to 20cm, and the ridge face width is 50 to 60cm. The invention can obviously reduce the unit weight of the no-tillage summer corn soil, increase the soil porosity, improve the physical behavior of the soil, increase the biological activity of the soil and enhance the biological fertility, facilitate the growing and development of the root system of the corn and increases the activity of the root system, and obviously improve the crop production and the benefits.
