Taro is eaten as food and vegetables, which can provide a large amount of nutrients for the human body; at the same time, taro can also be used in medicine processing and has certain health value. With the emergence of various advantages of taro, many foreign regions and domestic taro began to be planted in large quantities. From planting to harvesting, the use of scientific harvesting methods can not only improve harvesting efficiency and reduce taro loss rate, but also create more wealth for farmers and narrow the income gap between urban and rural areas. Compared with other root and tuber crops, taro has higher nutritional value. The tuber part, because it contains very fine and easily digestible starch, can be cooked into exquisite food. However, compared with other root and tuber crops, the harvesting method of taro is more cumbersome and complicated, and the degree of mechanized harvesting is far lower than that of harvesting other root and tuber crops.
