What is the appropriate temperature for growing potatoes

The suitable temperature for growing potatoes is generally between 15-20 degrees Celsius. Both high and low temperatures can affect the growth and yield of potatoes. Potatoes are a cool loving crop that grows best in an environment of 15-20 degrees Celsius. This temperature range is conducive to the formation and enlargement of potato tubers, while also promoting healthy plant growth. In this temperature range, the photosynthesis efficiency of potatoes is relatively high, and they can accumulate sufficient nutrients to supply tuber development. Excessive temperature can lead to slow growth and smaller tubers; If the temperature is too low, it may cause freezing damage or growth stagnation. When the temperature exceeds 25 degrees Celsius, potato plants are prone to heat stress reactions, manifested as yellowing of leaves and growth arrest. Continuous high temperatures can also cause the tubers to stop expanding, and even result in malformed or hollow potatoes. In environments with temperatures below 10 degrees Celsius, potato germination and growth are inhibited, and seedlings may suffer from freezing damage. Especially during the tuber formation period, if subjected to sustained low temperatures, it is easy to cause physiological diseases such as black heart disease inside the tuber. When planting potatoes, in addition to paying attention to temperature conditions, it is also necessary to pay attention to environmental factors such as soil moisture, light, and nutrient supply. Choose loose soil with good drainage, keep it moderately moist but not waterlogged. When planting in areas with high temperatures, heat-resistant varieties can be selected or planting time can be adjusted to avoid high temperature seasons. Reasonable fertilization, especially ensuring the supply of potassium fertilizer, can help improve the stress resistance and yield of potatoes. Regular inspections of the field conditions and timely prevention and control of pests and diseases are necessary to achieve an ideal harvest.
