The invention belongs to the technical field of crop planting, and specifically relates to an intercropping planting method for improving zinc concentration of wheat grains. A row-row intercropping planting method for different wheat varieties or a multi-species crop mixed cropping planting method is used in the intercropping planting method for improving zinc concentration of wheat grains. Zinc concentration of obtained wheat grains is improved to 40-60 mg/kg from 30 mg/kg, and the zinc concentration meets requirement of world health organization. The method effectively improves zinc concentration of the wheat grains, and the wheat grains are beneficial for eating.
