Application period 15 days before and after corn tasseling, and no later than the corn silking period, is the application period of corn granulation fertilizer. Too late, it is easy to cause corn to be late and ripe, affecting the planting of the next crop.
Types of Fertilizers Corn tapping fertilizers are not easy to apply fertilizers with long fertilizer efficiency. Quick-acting nitrogen fertilizers such as urea, ammonium bicarbonate and ammonium sulfate should be applied. These fertilizers are effective and beneficial to the accumulation of corn starch.
Fertilizer dosage The amount of the attacking fertilizer does not have to be too much, and too much is easy to cause the corn to be late. The specific topdressing amount should generally be determined according to the type of corn variety. Compact corn has strong fertility, large population and high productivity per plant. In the later stage, proper application of some fertilizers will not cause gluttony and late maturity, but will promote yield increase and fertilizer application. It should account for 20% of the total topdressing amount, and 8-10 kg of urea can be applied per mu. If the flattened corn topdressing amount is too much, it will cause late maturity and affect the sowing of the next crop. The topdressing amount should account for 10% of the total topdressing amount. 5 kg of urea can be applied per acre.
Timely watering When applying the attacking fertilizer, it must be watered in time to achieve the combination of fertilizer and water, promote the fertilizer with water, and give full play to the fertilizer production. If there is much precipitation in the later stage of corn growth and soil moisture, you can only fertilize without watering.
A top dressing of corn before the flowering of the loose powder is the corn attacking fertilizer. The attacking fertilizer is the last top dressing of corn. After the fertilizer is applied, the corn can be increased by 10% to 13%. However, since the corn plants are tall at this time, fertilization in the field is difficult, and production is often neglected.
