Water at the ear of corn

The ear of corn refers to the period from the jointing stage to the flowering stage of the tassel, which usually takes 25 to 30 days. The ear of corn is the most lush period of corn growth. It requires more water. In production, the main target of the ear stage is to achieve a large amount of roots, thick stems, wide leaves, thick green leaves and large grains.

At present, the temperature is high and there are many rainy weather. It should be noted to strengthen the management of fertilizer in the field. Fields with weak seedlings and poor soil fertility can properly topdress early and increase the amount of topdressing. In areas with more precipitation, it is necessary to pay attention to timely drainage so as not to affect root growth.

After the jointing, the weak plants are eliminated in time to reduce the cost of fertilizer and water, and improve the ventilation and light transmission conditions.

The main pests and diseases at the ear of corn include large spot disease, small spot disease, stem rot and corn borer.
