Planting corn: it is at this time that most high-yielding families of corn are fertilized. No wonder their yields are so high.

When is the best time for corn topdressing? What kind of fertilizer should I chase? Is urea okay? Can I apply it in a furrow between two ridges with a row spacing of 55 centimeters? Today we specially invite a senior agronomist to share our experience with us. Let's take a look at it.

Traditional corn planting generally uses a small seeder, the fertilizer is relatively shallow, in order to prevent burning seedlings, the general amount of base fertilizer is relatively small, so it is necessary to topdressing.

Corn

According to the requirements of high-yield cultivation, the time of topdressing corn should be in the small trumpet mouth stage, that is, 10 to 11 leaves. As soon as you enter the small trumpet mouth period, you should apply urea. At this time, about 20 jin of urea is enough.

The period of great effect is in the period of big trumpet mouth, and the total number of male leaves is about to enter the stage of big trumpet mouth at 13 or 14 leaves, and more than 30 jin of urea should be applied at this time. Combined with rainfall, if there is no rain, it is very important to water and top fertilize at this time.

The mastery of the loudspeaker period, if you have the experience to pinch it with your hand in the ground, and you can feel the male ear to the mouth after pinching to the top, this is the trumpet period, which is a critical period when you have to fertilize.

When you are looking for fertilizer, don't be stingy at this time. You must distinguish between the small loudspeaker period and the big loudspeaker period according to your own seedling conditions, and then top dressing later.

Corn

In addition, the planting of corn should generally be in the furrow between the ridges, open a shallow trench between the two ridges, and then apply fertilizer inside, and water it after covering the soil, which is the best.

These are all the contents of today's corn topdressing management. If you are not clear about today's sharing, or if you have other problems in the process of planting corn, you can consult in the comments section below.
