2 , pay attention to the cultivation method : According to the measurement, in the case of the same fertilizer and water, the celery cultivated on the plot with strong salt and alkali, relatively heavy, sandy and serious pests and diseases is prone to hollow disease. Therefore, cultivate celery should choose a plot rich in organic matter, water retention and fertility, and good drainage and irrigation conditions. Cultivate celery in the greenhouse, keep the temperature at 18 °C ~ 23 °C during the day , do not exceed 25 °C, keep the temperature at 13 °C ~ 18 °C, do not lower than 10 °C, and the ground temperature should be 13 °C ~ 18 °C. The base fertilizer should be applied, and the fertilizer in the growing season is dominated by quick-acting nitrogen fertilizer. It should be timely to top dressing and watering, not to take off the fertilizer, and take measures of small water and watering, thin fertilizer and diligent application. In the vigorous growth period of celery, it is necessary to supply water for fertilizer without interruption, and it should be topdressed every 15 to 20 days. Gibberellin has the effect of promoting the growth of celery, but it can only increase the output when the water and fertilizer supply is sufficient, the management measures are proper, and the celery itself is relatively thick.
