Taking summer corn as an example, the technology of "one increase and four changes" was implemented: increasing planting density reasonably according to variety requirements; Replace planting with density-tolerant varieties; Using no-tillage precision direct seeding technology, the density of direct seeding corn is suitable and the population uniformity is good; Changing extensive fertilization into soil testing formula fertilization; Change artificial planting into mechanized corn operation.

Select high-quality improved varieties, generally choose mid-late maturity varieties with high yield potential, strong density tolerance and large panicle type to ensure strong lodging resistance and good disease resistance. The varieties with strong lodging resistance have hard stems and developed roots.

Varieties with strong disease resistance are resistant to leaf spot in high population, such as Zheng Dan 958, Agricultural University 108, Denghai No.9 and Lu Dan 98 1 planted in Shudong Town. Seed purity is higher than 96%, germination rate is higher than 85%, and purity is higher than 98%.
