V. Conclusions
Millet, as an ancient food crop, plays an important role in the history of China's agricultural development. It not only provided important food for the ancient ancestors of our country, but also carried rich cultural connotations. Although the development of modern agriculture has led to the decline of millet, its nutritional value and medicinal value are still worthy of our attention and exploration.
