Lettuce likes cold environment. It is neither cold resistant nor heat resistant. The suitable temperature for growth is 15 ℃ - 20 ℃, and the growth period is 90-100 days. The seeds are resistant to low temperature and can germinate at 4 ℃. The suitable temperature for germination is 18-22 ℃, and it hardly germinates when it is higher than 30 ℃. During plant growth, I like cold climate. It is most suitable to grow at 15-20 ℃, with high yield and good quality; When the temperature is higher than 25 ℃, the growth is poor, the leaves are coarse and old, and have a slight bitter taste. But cold resistance is also quite strong. 0 ℃ or even short-term subzero low temperature does not hinder growth.
