Potato is a perennial herb of Solanaceae and the third largest food crop in the world after wheat and corn.
Because potatoes are very suitable for planting in cold areas where the original grain yield is extremely low and only naked oats can be planted, they are rapidly popularized in Inner Mongolia, Hebei, Shanxi, northern Shaanxi and other places. High-yield crops such as potatoes, corn and sweet potatoes imported from the United States have become the main food for the poor and played an important role in maintaining the rapid population growth in China.
