After the application of the fertilized corn to the big trumpet period, it is the most suitable period for applying the panicle fertilizer, which generally increases the yield of summer corn by 15% to 20%. It should be applied according to the ground force and growth for 10 to 15 days before the corn is taken. If the soil is poor, the base fertilizer is small, and the growth is weak, it should be 1500 kg per mu, and 7 to 8 kg of urea, mixed with or applied to the hole; medium corn, 1000 kg per mu, 5 to 6 kg of urea. Into the growth and vigorous, 600 kg of manure water per mu, 4 to 5 kg of urea. In case of drought, watering or furrow irrigation should be carried out after fertilization to promote decomposition and absorption of fertilizer.

The application of the grain-fertilizer fertilizer should be carried out after the tassel, that is, the flowering and silking stage. According to the growth of the corn, 5 to 7.5 kg of urea per mu is applied.

Spraying fertilizer to promote grouting The plot showing the lack of fertilizer during the filling stage can be quickly replenished by foliar topdressing, using 1% to 2% urea solution, 3% to 5% superphosphate leaching solution or 0.1% to 0.2%. Foliar application of potassium dihydrogen phosphate solution can prolong the functional period of the leaf and promote the filling and firming.
