Arachis hypogaea, commonly known as the peanut or groundnut, is an annual herbaceous plant in the legume family Fabaceae. Native to South America, it is widely cultivated in tropical and subtropical regions around the world. The plant is unique in that its flowers develop above ground, but the pods containing the seeds mature underground.
Peanuts require full sun and warm temperatures to thrive. They prefer moderate humidity and should be watered regularly, allowing the soil to dry out partially between waterings. They are best grown outdoors in a sunny location with good air circulation.
収穫
Arachis hypogaea, commonly known as peanut, is typically ready for harvest about 120 to 160 days after planting, with the average being around 140 days. Harvesting should be done when the leaves start to yellow and the inner shells of the pods have a darkened color. To harvest, the entire plant is usually pulled from the ground, and the pods are then separated from the roots. It is important to allow the pods to dry properly to avoid mold and ensure good storage quality. Harvesting should ideally be done in dry weather to prevent moisture-related issues.
土壌
Peanuts grow best in well-draining, sandy loam soil with a slightly acidic to neutral pH. The soil should be loose and friable to allow the pods to develop underground. Good drainage is essential to prevent root rot.
肥料
Peanuts benefit from a balanced fertilizer with a higher phosphorus and potassium content, such as 5-10-10. Fertilize at planting and again mid-season to support healthy growth and pod development.
植え替え
If growing peanuts in containers, repotting is generally not necessary as they are annuals. However, ensure the container is deep enough to accommodate the developing pods and has good drainage.
伝搬
Peanuts are propagated by seeds. Plant the seeds directly in the soil after the last frost date when the soil has warmed. Space the seeds about 2 inches apart and cover with 1-2 inches of soil. Keep the soil moist until germination.
剪定
Pruning is not typically required for peanuts. However, removing any damaged or diseased foliage can help maintain plant health.
毒性
Peanuts are not toxic to pets or humans. However, they can cause allergic reactions in some individuals. All parts of the plant are generally safe, but the seeds (peanuts) are the most commonly consumed part.
追加
Peanuts are nitrogen-fixing plants, which means they can improve soil fertility by adding nitrogen. This makes them a good crop to rotate with other plants that deplete soil nutrients.
