Cultivation method capable of improving high-temperature-resistant planting performance of summer corn

The invention belongs to the technical field of summer corn planting and particularly relates to a cultivation method capable of effectively improving high-temperature-resistant planting performance of summer corn. According to the cultivation method capable of improving high-temperature-resistant planting performance of the summer corn, the planting date is delayed to mid-to-late June, an original common equal-spacing sowing manner is changed into a narrow-spacing and wide-spacing interval planting manner, a chemical control agent is sprayed on leaf surfaces of corn at the big flare stage forexternal regulation, foliage fertilizer is sprayed on leaf surfaces as assistance for regulation after high-temperature damage, under synergistic effect of all the links, the effects of high-temperature stress on the corn planting yield is effectively relieved, and production and yield are guaranteed. 本发明属于夏玉米种植技术领域，具体涉及种有效提高夏玉米耐高温种植性能的栽培方法。本发明所述提高夏玉米耐高温种植性能的栽培方法，通过将种植播期推迟到6月中下旬，并通过改变原有常见的等行距的播种方式为窄行距和宽行距间隔种植，以及通过在玉米大喇叭口
