Temperature management buckle shed early, enough light, high temperatures, pay attention to timely ventilation, day temperature control in the 18 ℃ ~ 22 ℃, night temperature 13 ℃ ~ 15 ℃, to promote the rapid growth of aboveground and underground to prevent Celery yellow leaves and leggy. When the outside temperature drops, there is a cold wave, you should gradually reduce the ventilation.

Cold winter 2 to 3 days through a wind, night temperatures should be maintained at 3 ℃ above, to ensure celery is not frozen.
