Efficient cultivation method for corn in semi-arid region

The invention belongs to the technical field of corn cultivation, and provides an efficient cultivation method for corn in a semi-arid region. The method includes the steps of removing weeds and stones in a planting area, and adjusting the pH value of soil; performing fertilization and soil loosening treatment on planting belts; sowing corn seeds on the planting belts and covering the planting belts with topsoil; conducting irrigation after sowing, in a jointing stage, in a large horn mouth stage, in a spinning stage and in a filling stage; and performing pest killing and weeding management on the planting area. The planting mode of the planting belts is a single-row mode or a large-ridge double-row mode; the irrigation depth after sowing is 45-55 mm; and the irrigation depths of the jointing stage, the large horn mouth stage, the spinning stage and the filling stage are 25-35 mm. According to the efficient cultivation method for the corn in the semi-arid region, the yield, the average filling rate, the light
