The suitable temperature for germination and seedling growth is 25-30°C; From the 6th true leaf to the budding stage, the leaf growth period lasts for 7-21 days; from budding to the harvest of the sprouts, the sprout formation period is carried out. The suitable temperature is 15-20℃. The day temperature is 20℃ and the night temperature is 15℃. At ℃, the sprouts develop well and the yield and quality are both good. If the temperature is too high or too low, the sprouts will be slender, the yield will be low, and the quality will be poor.
