扁豆, also known as broad beans or fava beans, are a type of legume that are widely cultivated for their edible seeds. They are typically flat and broad, with a green or brown color, and are rich in protein, fiber, and essential nutrients. These beans are commonly used in various cuisines around the world, often found in dishes like stews, salads, and dips. In addition to their culinary uses, 扁豆 are also valued for their agricultural benefits. They can improve soil fertility through nitrogen fixation, making them a popular choice for crop rotation. This helps maintain healthy soil and supports sustainable farming practices.
