What should I do if the corn seedlings turn yellow after being flooded?

When the corn is flooded and yellow, it should be drained in time. Once water is found in the field, deep ditches should be dug as soon as possible to lead the water away from the field, so as to reduce the temperature and humidity of the soil and air in the field and promote the recovery of plant growth.

Waterlogging of cultivated plants often causes lodging. If the waterlogging occurs in advance, plants can resume their upright growth on their own.

But now it is about to enter the stage of big trumpet mouth, and the plant has lost its ability to restore upright growth after lodging, so it needs to be lifted manually and fixed by soil cultivation.

However, we should try our best not to damage the newly born aerial roots, pay attention to removing the sediment on the leaves and restore the normal photosynthesis of plants.
