A method for improving corn yield by applying fertilizer without following up
By separating the fertilization into seedling initiation zone and main fertilizer supply zone, and combining it with rhizosphere-triggered compound granules, the problem of mismatched fertilization during the seedling and mid-to-late stages of corn growth has been solved in existing technologies, achieving stable nutrient supply and efficient utilization throughout the corn growth period.

Abstract
The application discloses a kind of corn yield can improve fertilization method of follow-up fertilization, it is related to corn cultivation fertilization technical field, in corn sowing period simultaneously forms seedling strip fertilization position, main fertilizer strip fertilization position and sowing position, seedling strip fertilization position is located 4-6cm in seed side and 4-6cm under seed, main fertilizer strip fertilization position is located 8-12cm in seed side and 12-16cm under seed.Seedling strip is input seedling particle, main fertilizer strip is input rhizosphere trigger type composite particle, the rhizosphere trigger type composite particle includes ammonium preservation nitrogen storage core, switchable nitrate inhibition layer, rhizosphere gate opening layer and water migration resistant outer layer from inside to outside.VE to V6 stage main fertilizer strip maintains low release state, V6 to V8 stage switches to high release state after node root expands to main fertilizer strip fertilization position and rhizosphere organic acid increases and acidification occurs.
