High yield of corn

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.

The application period is 15 days before and after the corn is squished, and at the latest, it does not exceed the corn spinning stage, which is the application period of the corn granulation fertilizer. Too late, it is easy to cause corn to be late and ripe, affecting the planting of the next crop.

Fertilizer type corn attacking fertilizer is not easy to apply fertilizer with long fertilizer efficiency. It should be applied with quick-acting nitrogen fertilizer, such as urea, ammonium bicarbonate and ammonium sulfate. These fertilizers have quick effect and are beneficial to the accumulation of corn starch.

The amount of fertilizer used to attack the fertilizer does not have to be too much, too much is also likely to cause corn to be late and ripe. 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 and attacking fertilizer must be timely watered to achieve the combination of fertilizer and water, to promote fertilizer with water, and give full play to the effect of fertilizer production. If there is much precipitation in the later stage of corn growth and soil moisture, you can only fertilize without watering.
