Growing conditions

1. Temperature: Likes to be cool and not tolerant of high temperatures. During the growth period, the daily average temperature is 17℃ ~?21 ℃ is suitable.

2. Light: The light intensity is high, the light interaction intensity of the leaves is high, the tubers are formed early, and the tuber yield and starch content are both high.

3. Moisture: The transpiration coefficient of potatoes is between 400 and 600. If the total rainfall is between 400 and 500 mm and is evenly distributed during the growing season, the water needs of potatoes can be met.

4. Soil: Plants have very strict requirements on soil. Soil with deep topsoil, loose structure, good drainage and ventilation, and rich in organic matter is most suitable, especially soil with large porosity and good ventilation. It can better meet the oxygen needs of root development and tuber growth.
