Growth Conditions

Potatoes like cold weather and are a crop that likes low temperatures. The formation and growth of underground tuber tuber requires loose, breathable, cool and moist soil environment.

Potato temperature requirements: The suitable temperature for tuber growth is 16℃~18℃. When the local temperature is higher than 25℃, the tuber stops growing; the suitable temperature for stem and leaf growth is 15℃~25℃. Growth stops above 39°C.

Potatoes were introduced to China only over 300 years ago. It is said that it was introduced by overseas Chinese from Southeast Asia. In the 21st century, China's potato planting area ranks second in the world. Potatoes have high yields, rich nutrition, and strong adaptability to the environment. They are now spread all over the world. In tropical and subtropical countries, they can be cultivated and obtain higher yields even in winter or cool seasons.
