The root of the peanut grows in the soil, but its flowers, leaves and stems grow on the ground.But after it blossoms, a fruit needle will grow inside the corolla, which is composed of ovary and ovary handle.This fruit needle has geotropism, after five or six days of stretching, it will drill into the soil, the ovary will fall into the soil, and then develop and expand into fruit under suitable conditions.So its roots and fruits are growing in the soil, but the leaves and stems will be on the ground.This is actually the origin of "peanuts".
After pollination, the flower of peanut will form an ovary stalk at the base of its ovary within four or five days, which is elongated and shaped like a needle, so it is called a fruit needle.And because the ovaries need to be in a dark environment to develop and expand into fruit, the fruit needles will drill into the soil.In the dark soil environment, water and nutrients are relatively abundant, so the ovary can expand rapidly and gradually develop into fruit.Only the growing conditions in the soil can promote the development of ovaries, so the fruits of peanuts will grow in the soil.
Seed selection: First select high quality, plump peanut seeds, potted peanuts, then because the space is limited, generally select three or four good.After selecting the seeds, soak them in warm water overnight for germination.
Seeding: Prepare a flowerpot of suitable size, fill the flowerpot with loose and breathable soil, and spray some water to moisten the soil.Then the germinated seeds are buried in the soil to a depth of about two or three centimeters.Then cover it with a thin layer of soil and spray it with water.The flowerpot can also be covered with a plastic film, which can have a certain function of heat preservation and moisture preservation.
Management: Move the flowerpot wrapped with the film to a place with mild and sufficient light to avoid being exposed to the sun.In this way, you can wait for about one to see the seeds germinate, at this time, you can tear off the plastic film and water it on time every day.
