Detailed Explanation of Corn Replanting Methods and Precautions

Missing corn seedlings is a very common phenomenon, and many farmers choose to replant their corn. So, how is corn replanted? What are the corn replanting methods and precautions? Let's take a look together!

1. How is corn replanted?

1. Variety selection: Choose a variety with a growth period 10—15 days shorter than the originally planted variety. If low temperatures after sowing extend the emergence time, choose a variety with a suitably shortened growth period.

2. Seed treatment: When replanting with a hole-punching tool, the seeds should first undergo seed selection, coating, and drying before sowing.

For manual replanting, first sprout the seeds, then sow. Note that sowing must be done on moist soil, with a small amount of soil cover (less than 3 cm) and then pressed firm to prevent “sprout drying”.

3. Replanting: If there is 1 missing seedling between rows, there is no need to replant. If 2 seedlings are missing in a row, replant 1 in the middle; if 3 are missing, replant 2 hills, …… and so on. Note: The first hill and the last hill of the replanted corn should be at least 1.5 times the normal plant spacing from the corn seedlings that have already emerged, to prevent large and small seedlings from competing for water and fertilizer and shading each other. The spacing between the replanted corn plants can follow the normal plant spacing required by the variety.

Replanting corn is a supplement to the deficiencies of the first round of planting. Correct replanting can not only increase corn income but also improve land utilization, and for farmers it can also increase income. Therefore, when farmers replant corn, they must master scientific replanting methods to avoid suffering losses again.
