This invention discloses a method for promoting the maturity of maize replanted after wheat in the Yanqi reclamation area, specifically including the following steps: Step 1, variety selection; Step 2, seedling preparation and management; Step 3, land preparation; Step 4, transplanting operation; Step 5, field management. This invention relates to the field of maize cultivation technology after wheat. This method of maize cultivation by transplanting seedlings after wheat, through the selection of early-maturing varieties with a full growth period, combined with pre-harvest seedling raising before wheat harvest, perfectly addresses the problem of insufficient effective accumulated temperature after wheat, ensuring normal maturity of maize within a limited growth cycle and avoiding yield reduction or crop failure due to insufficient accumulated temperature. By treating the substrate with chlormequat chloride, precisely controlling the temperature and humidity of the seedling shed, and hardening off seedlings before transplanting, it effectively suppresses tall, weak seedlings, reduces pests and diseases, and cultivates strong seedlings. During transplanting, the soil around the roots is compacted, and water is sprayed to retain moisture before loading. Combined with the suitable seedling age of 2 to 5 leaves and 1 heart, the survival rate of transplanted maize is significantly improved, and the rate of empty stalks is reduced.
