According to statistics, there are about 70,000 or 80,000 species of edible plants on the earth, of which about 150 species can be cultivated on a large scale. So far, only more than 20 species are widely used by human beings, but they account for 90% of the world's total grain output. Domesticated animal and plant species basically constitute the basis of world agricultural production. Like other countries in the world, the communication and spread of edible species and food in China has never been interrupted since ancient times, which not only expanded the food sources of China people and enriched the dishes of China people, but also changed the eating habits of China people and enriched the daily eating life of China people. ◎ Corn originating in America was introduced into northern China through Europe, Africa and West Asia; ◎ Potatoes between staple food and vegetables were introduced into China through the southeast coast.

About the middle of16th century, China began to introduce corn. Sweet potato originated in America. The first batch of sweet potatoes in Europe was brought back by Columbus in 1492, and then introduced to Africa by Portuguese and Asia by Pacific islands. Sweet potato was first introduced to China in Wanli period of Ming Dynasty. At that time, Chen Zhenlong, an overseas Chinese in Fujian, often went to Luzon (now the Philippines) to do business, and found that the yield of sweet potatoes produced in Luzon was the highest, so he patiently learned the planting methods from local farmers. Later, after the promotion of the Chen family, sweet potatoes were widely planted all over the country. Tobacco, peanuts and pumpkins are all American plants. After Columbus discovered the New World, peanuts were introduced from coastal areas to inland areas in about 1530.
