The invention relates to a method for increasing the per unit area yield of summer corn by equal-row-spacing staggered-plant planting, which comprises the following steps: the planting mode is equal-row-spacing staggered-plant planting, the staggered-plant planting refers to staggered arrangement of two adjacent rows of corn plants between rows, and single plants in one row of corn plants are aligned with middle lines between plants in the other row of corn plants; the planting density is 82000 +/-20/hm < 2 > to 90000 +/-20/hm < 2 >; in the summer corn planting period, the application amount of the nitrogen fertilizer is based on nitrogen, and the total nitrogen application amount is 225-300 Kg/hm. According to the method, the yield can be obviously increased by increasing the planting density, the thousand seed weight under the close planting level and the harvested ear number under high close planting are obviously increased by matching with staggered-plant close planting, the ear seed number is stabilized,
