Potatoes are called potatoes, belonging to Solanaceae and Solanum panicum miliaceum. Potato is one of the important food crops in the world, also known as potato, potato head, sweet potato, potato potato, potato potato, potato potato potato, potato potato potato, potato potato potato and potato egg. Potatoes are native to the Andes in South America, and are now cultivated evenly all over the world.

Under certain conditions, potato plants grow and develop in close coordination with roots, stems and leaves. When the seedlings are unearthed, the green stems and leaves begin to use photosynthesis to make nutrients, and the well-developed roots absorb enough water and inorganic elements from the soil for the growth and utilization of all parts of the plant.

Details:

In the Ming Dynasty, there was a special institution in the court to grow potatoes, but this institution only served the court, and the seeds and planting techniques of potatoes would not be introduced to the people at all. Therefore, although potatoes were introduced to China in the Ming Dynasty, the vast majority of ordinary people had no chance to use them.

After the Qing Dynasty, the organization in charge of potato planting in Ming Dynasty was banned, and the planting personnel of the organization were demoted, so the potato planting technology and seeds had a chance to be introduced to the people. Therefore, potatoes were gradually popularized in Beijing and even the whole country.

By the middle and late Qing Dynasty, due to the increasing population, the demand for food was increasing, and traditional crops such as rice and wheat could no longer meet the food supply. In this case, it is imperative to plant potatoes on a large scale throughout the country.

During Daoguang period of Qing Dynasty, northwest China has become an important potato producing area, and the planting technology and yield have been continuously improved, making it the third largest grain variety in China.
