2. During the celery growing period, the growing environment must be kept highly humid and cool, and shade management and high-humidity cultivation must be implemented. Cover the growing area with a shade net to prevent direct sunlight on the plants. At the same time, deepen the furrow to 40-60 cm and fill it with water. Water once in the morning and once in the evening to keep the soil moist, prevent water shortage and drought, and ensure water supply.
3. The main diseases and pests of celery are early blight, leaf spot, and aphids.
In the early stage of disease onset, spray with 75% chlorothalonil 600 times solution or Bordeaux mixture at 1:0.5:200 plus 0.1% sulfur powder. Spray 30-40 kg of solution per 667 sq m, once every 7 days, for 2-3 consecutive sprays. For insect pests, spray with 0.4% aphid-killing essence 400-600 times solution plus 0.1% laundry detergent, or spray with 50% dichlorvos 500-600 times solution for control.
