1. Sowing: a living seed is buried in the soil. If the temperature and humidity are appropriate, it will grow seedlings after 6 days or so. When it reaches the third leaf stage, the nutrition in the seed will be exhausted, which is the first stage of weaning, that is, the first stage of corn.
2. Jointing: the three leaf stage is the first turning point of corn. It will change from autotrophic to heterotrophic. This stage is mainly the flower splitting of roots, leaves and stems. During this period, drought tolerance and waterlogging will lead to the death of seedlings. Mild drought is conducive to the development of roots.
Ear stage refers to the period from jointing to heading, which is the second turning point of maize. At this stage, its nutrition and reproduction are carried out simultaneously, which is the most vigorous stage of growth and development, and also the most important period of management. It's best to apply fertilizer to supplement enough nutrients, promote leaf growth, stem firmness, so as to achieve the goal of large ear and more ears.
The stage from staminate to mature is called anthesis. At this time, all the leaves have been unfolded, and the plant has also been set to grow. Entering the stage of reproductive growth, it is also the third turning point. During this period, we should protect leaves from premature senescence and damage, and strive for more and heavier grains to achieve high yield.
