Zinc fertilizer should be applied before the maize trumpet period. If zinc deficiency symptoms have already been shown, timely spraying of zinc-containing foliar fertilizer can effectively alleviate the problem. Zinc fertilizer should be applied or sprayed with basal fertilizer, but the effect of basal fertilizer is best. When fertilizing, it should be applied or applied. Zinc sulphate-based application of 1 to 1.5 kg per mu, if sprayed, the concentration is controlled at 0.2%, with 2 to 3 barrels of water per mu. In addition, other micronutrients can be added to corn, such as boron (0.5 kg per mu for boric acid) and manganese (1 to 2 kg per mu for manganese sulfate), especially for alkaline soils. Increasing micronutrients can significantly increase yield.
