Celery heart rot is a common physiological disease in celery production in spring. The tender tissue of celery grows black and dies. Subsequently, the celery root system and some stems and leaves also died one after another. The prevention and control methods are as follows: first, rational fertilization. Apply sufficient base fertilizer and increase phosphorus and potassium fertilizer and boron fertilizer to cultivate strong plants to improve disease resistance. Do not use too much nitrogen and potash fertilizer to avoid blocking boron absorption. Second, do not make the border surface too dry. Rational irrigation, not flooding. At low temperature, heat preservation and irrigation should be carried out properly. Third, timely removal of disabled bodies, reasonable close planting, increase ventilation and transmittance.
