Growth conditions of potatoes

1, temperature: people like to be cold and cool, and they are not resistant to high temperature. The average daily temperature during the growth period is17℃ ~ 21℃.

2. Illumination: The light intensity is high, the leaf photosynthesis intensity is high, the tuber forms early, and the tuber yield and starch content are high.

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

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

5. Nutrition: The growth and development of potatoes need more than ten kinds of nutrient elements, and the demand for fertilizer is the most, followed by nitrogen and the least.
