Where do corn seeds come from?

The male flowers grow on the top of the corn, which will release pollen on sunny days. The pollen is then spread by wind to the filaments of the female ears in the middle, and then forms grains. After maturity, the seeds are spread by people, animals, etc. The grains on the corn are corn seeds.

What do corn seeds look like?

Corn seeds mainly consist of three parts: seed coat, embryo and endosperm. The seed coat is mainly composed of cellulose, has a shiny surface and no color. It surrounds the entire seed and can protect the seed from external mechanical damage and prevent the invasion of pests and diseases.

Corn seed dispersal

Most corn needs to be sown by manpower, but a small amount of corn is spread by animals and itself. It has a strong vitality and can take root and sprout as long as the surrounding environment is suitable.

How to get corn seeds

Corn seeds can be harvested manually or mechanically. When the corn is ripe, the corn cobs can be broken off manually. Many areas now carry out mechanized agricultural production, which can improve labor efficiency while reducing labor intensity.

Corn seeds planting

1. Growth process

The growth process of corn seeds mainly includes the following processes: corn seeds absorbing water and swelling, transformation of nutrients in the embryo, seed germination, hypocotyl elongation, radicle elongation, plumule growth, emergence from the soil, and plumule leaf elongation.

2. Sowing time

Corn sowing should be done at a ground temperature of 10-12℃. In the north, where spring corn is the main crop, special attention should be paid to the sowing temperature to avoid the inhibition of seed germination due to low temperature. The common reason why seeds do not germinate is that they are planted at low temperatures and at high humidity, causing the seeds to rot and not germinate.

3. Planting method

Before sowing corn, the land needs to be prepared and sufficient base fertilizer needs to be applied. Corn seeds do not need to be germinated and can be sown directly. The depth should be shallow, about 3-5 cm. In addition, the seeds can be mixed before sowing. Mixing the seeds with pesticides or fungicides can reduce diseases and pests.
