How to apply high-yielding corn fertilizer
A top-dressing fertilizer before corn pollen blossoming is corn attacking grain fertilizer. The attacking grain fertilizer is the last time the corn is top-dressed. The top-dressing fertilizer can increase the yield of corn by 10%~13%. However, due to the fact that the corn plants are tall and fertilized in the field, they are often overlooked in production.
1. Application period: 15 days before and after corn tasseling, no later than corn silking period, is the application period of corn attacking pellets. Late, it is easy to cause late-maturing corn, affecting the sowing of the crop.
2. Fertilizer types: Fertilizers with long effective fertilizers for corn attacking fertilizer should be applied with available nitrogen fertilizers such as urea, ammonium bicarbonate and ammonium sulfate. These fertilizers are effective and are beneficial to the accumulation of corn starch.
3. Fertilizer dosage: The dosage of attacking pellets does not need to be too much, and too much can easily cause late-maturing corn gluttony. The specific top-dressing amount should generally be determined according to the type of corn. Compact maize has strong fertility, large groups, and high productivity per plant. Applying more fertilizer in later stages will not only result in late-maturing glutinous rice, but will increase the yield and increase the amount of fertilizer. Should account for 20% of the total fertilizer, 8~10 kg of urea can be topped per acre. Excessive amount of top-dressing corn will cause late-maturing glutinous crops, affecting the sowing of the next crop, and top dressing should account for 10% of the total fertilizer. Each acre can be topped with 5 kg of urea.
4. Watering in time: When applying the attacking grain fertilizer, it must be watered in time so that the combination of fertilizer and water can be promoted by water and the production of fertilizer can be fully utilized. If there is more precipitation in the later stage of corn growth and the soil moisture is enough, you can only apply fertilizer without watering.
