Banana (scientific name: MusananaLour.) belongs to Musaceae, also refers to its fruit. Widely cultivated and eaten in tropical areas. Bananas are delicious, nutritious and can be harvested all year round, and are also highly valued in temperate regions. The plant is a large herb, which emanates from the rhizome and forms a false stem with a height of 3 ~ 6 meters (1 ~ 2 feet) from the lower part of the leaf sheath.
