Growing 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.

The leaflets are often alternate in size, 10-20 cm long; the petiole is about 2.5-5 cm long; the leaflets are 6-8 pairs, oval to oblong, the largest one can be up to 6 cm long and 3.2 cm wide, and the smallest one is long and wide.

The corymbs are terminal and posterior, with white or blue-purple flowers; the calyx is bell-shaped, about 1 cm in diameter, sparsely pubescent on the outside, with 5 lobes, the lobes are lanceolate, and the apex is long and acuminate. ; Corolla radial, about 2.5-3 cm in diameter, corolla tube hidden in the calyx, about 2 mm long, crown eaves about 1.5 cm long, lobes 5, triangular, about 5 mm long; stamens about 6 mm long, anthers long 5 times the length of filaments; ovary oval, glabrous, style about 8 mm long, stigma capitate.
3. Fruit shape
Potatoes are spherical, smooth, brown or purple-brown, about 1.5 cm in diameter. Seeds kidney-shaped, yellow. Flowering season is summer.
