Seedling stage: The seeds are buried in the soil, and the seedlings will grow out in about 6 days. When they reach the three-leaf stage, they will transform from autotrophic to heterotrophic. During this period, they are tolerant to drought and afraid of waterlogging. The ear stage: Its nutrition and reproduction are carried out at the same time. It is the most vigorous stage of growth and development. Sufficient nutrients must be supplemented. Flowering stage: The leaves have unfolded and the plant has reached a certain length, entering the stage of reproductive growth.

1. Seedling stage

1. Seedling stage

1. Sowing: A living seed is buried in the soil. If the temperature and humidity are suitable, small seedlings will grow in about 6 days, and they will grow to three leaves. During this period, the nutrients in the seeds will be exhausted, which is the weaning stage, which is the first stage of corn.

2. Jointing: The three-leaf stage is the first stage of corn At a turning point, it will switch from autotrophic to heterotrophic. This stage is mainly about the division and flowering of roots, leaves and stems. During this period, it is drought-tolerant and afraid of waterlogging. Waterlogging will lead to dead seedlings, while mild drought is conducive to root development.

2. Ear Period

Ear The period refers to the period from jointing to tasseling, which is the second turning point of corn. At this stage, its nutrition and reproduction are carried out at the same time. It is the most vigorous stage of growth and development, and it is also the most important period of management. It is best to carry out top dressing to supplement sufficient nutrients, promote the enlargement of leaves and firm stems, so as to achieve the purpose of large ears and many ears.

3. Flowering and Grain Stage

The stage from tasseling to maturity is called the flowering and grain stage. At this time, all the leaves have expanded and the plant has reached a certain length. It has entered the reproductive growth stage, which is also its third turning point. During this period, it is necessary to protect the leaves from premature aging and damage, so as to achieve more and heavier grains and achieve a high yield.
