Guyuan Potatoes

Guyuan Potatoes

　　      Potatoes, scientifically known as Solanum tuberosum, are commonly called "potatoes" or "tudan" (literally "earth eggs"). In Guyuan, people refer to them as "life-saving eggs" and "treasure eggs" due to their two broads and two highs—broad adaptability, broad use, high yield, and high economic value.

　　      Potatoes originated in South America and have a history of 1,800 years. Today, 79% of the world’s countries grow potatoes, covering an area of over 300 million mu, with a total output of more than 300 million tons. In China, the history of potato cultivation spans less than 300 years. But now, they are grown across the country, covering nearly 70 million mu, with a total production of about 60 million tons. Both figures rank first in the world. (Yinchuan)
