What season is corn?

It usually grows in summer and matures in autumn. Corn is panicum miliaceum, belonging to Gramineae and Zea, also known as corn, reed, Hosta, corn, cob and so on. The stem is very erect, and the height is about1-4m. The fruit produced by corn is long and cylindrical, with bonzi grains arranged on it, and the grains inside turn yellow when they mature.

The fibrous root system is strong, with supporting roots, thick stalks and monoecious plants. Male panicles are terminal panicles, and female panicles are spikes born in leaf axils. It originated in Mexico or Central America and is now cultivated all over the world.

Growth conditions of maize:

1, requirements for soil and soil improvement

Corn does not require high soil conditions and can be planted on a variety of soils. The soil with deep soil layer, good structure, high fertility level, rich nutrition, loose ventilation, easy discharge of energy storage, near neutrality and coordination of water, fertilizer, gas and heat is suitable for planting.

2. Requirements for nutrients and fertilization

Corn has a short growth period and rapid growth and development, which requires more fertilizers, especially the absorption of nitrogen, phosphorus and potassium.

3. Corn water demand and irrigation drainage.

Corn needs more water, so it is necessary to control water properly at seedling stage and then meet the requirements of corn for water in order to obtain high yield.

4. Temperature requirements of corn

Corn is a thermophilic crop and sensitive to temperature. At present, the total accumulated temperature of maize varieties used in growth period is 1800-2800℃. Different growth stages require different temperatures.

5. The requirements of corn for light.

Corn is a short-day crop, which likes light and needs strong light throughout its growing period. Under the sunshine of 8- 12 hours after emergence, it develops quickly, blooms early and shortens the growth period, and vice versa. Under strong light, the net photosynthetic productivity of maize is high, and the organic matter moves fast in the body, otherwise it is low and slow.
