Lupinus albus, commonly known as white lupin, is an annual plant in the Fabaceae family. It is native to the Mediterranean region and is widely cultivated for its seeds, which are used as food and fodder. The plant prefers subtropical climates and is known for its attractive, tall spikes of white flowers.
White lupin requires bright, direct sunlight for optimal growth. It thrives in moderate temperatures and prefers a humid environment. Regular watering is necessary, but the soil should be allowed to dry out partially between waterings. The plant is best suited for outdoor cultivation.
收成
Lupinus albus, commonly known as white lupin, should be harvested when the pods turn brown and the seeds inside are hard and dry. This typically occurs about 120 days after planting. To harvest, cut the plants at the base and allow them to dry further if necessary. Once fully dried, thresh the pods to release the seeds. Ensure that the seeds are completely dry before storage to prevent mold and spoilage.
土壤
White lupin prefers well-draining loamy soil with a slightly acidic to neutral pH. The soil should be kept moderately moist but not waterlogged. Good drainage is essential to prevent root rot.
肥料
A balanced fertilizer with a nutrient composition of 5-10-10 is recommended. Fertilize the plant during the growing season to support healthy growth and flowering.
换盆
As an annual plant, white lupin does not typically require repotting. However, if grown in containers, ensure the pot is large enough to accommodate the plant's root system and repot if necessary to provide fresh soil.
传播
White lupin is propagated by seeds. Sow the seeds directly in the soil in early spring after the last frost. Ensure the soil is well-prepared and keep it moist until the seeds germinate.
修剪
Pruning is not generally required for white lupin. However, removing spent flowers can encourage further blooming and maintain the plant's appearance.
毒性
White lupin contains alkaloids that are toxic to pets and humans if ingested. All parts of the plant, especially the seeds, should be handled with care and kept out of reach of children and animals.
