栗树, or the chestnut tree, is a deciduous tree known for its edible nuts, commonly referred to as chestnuts. These trees can grow up to 30 meters tall and are characterized by their broad, serrated leaves and spiky husks that contain the nuts. They thrive in well-drained soil and are often found in temperate regions. The chestnut tree is significant not only for its nuts, which are a popular food source, but also for its wood, which is valued in construction and furniture making. Additionally, these trees play a role in local ecosystems, providing habitat and food for various wildlife species.
