The specific methods for applying zinc fertilizer to corn are as follows:
1. Base application Mu with 1-2 kg of zinc sulphate mixed with fine soil 10-15 kg or acupoint application.
2, chasing the application of 1-2 kg of zinc sulphate mixed with fine soil 10-15 kg, in the seedling period to jointing period or acupoint application.
3, spraying with 0.1% zinc sulphate solution in the seedling period to jointing period of continuous spraying twice, each interval of 7 days, the amount of liquid per acre is 50-75 kg, when the concentration exceeds 0.4%, there will be fat damage.
4. Soaking seeds Soak seeds with 0.02-0.05% zinc sulfate solution for 6-8 hours. When the concentration exceeds 0.1%, it has an effect on germination.
5. Seed dressing Calculate the amount of fertilizer with 4-6 grams of zinc sulfate per kilogram of seed. First dissolve the zinc sulphate in the sprayer, add an appropriate amount of water, then stir the seeds while spraying, and dry them before seeding.
In addition, when applying zinc fertilizer, it is necessary to pay attention to the combined application of nitrogen and phosphorus fertilizers in order to exert greater benefits. The suitable amount of nitrogen and phosphorus is 7.5 kg per mu and 2.75-7.54 kg of phosphorus pentoxide.

Technology for increasing yield of zinc fertilizer in corn
Zinc is one of the essential nutrients for corn. Corn is a zinc-sensitive crop. Zinc deficiency is a whitening seedling. When zinc deficiency occurs, it stops growing and even kills seedlings. The application of zinc fertilizer can overcome the symptoms of zinc deficiency, promote growth and development, increase the number of grains per panicle and 1000-grain weight, and can mature early, and apply 1-2 kg of zinc sulfate per mu, and the yield of corn is significantly increased.
