After the planting of celery, a new high-fat film insulation was applied in a timely manner to increase the survival rate. In the event of a violent storm, sunny days at noon shade 2 to 3 days, after planting can be watered 2 to 3 times. After moderate seedlings, appropriate seedlings are planted in deep tillage. When the minimum temperature dropped to 5°C, attention should be paid to heat preservation at night, and during the day, the air should be cooled to reduce temperature and humidity, to prevent the plants from being long and ill. The daytime temperature should be kept at 20°C～25°C and 10°C at night. In mid-November, straw curtain insulation should be stamped. Every day should be released for more than 2 hours. Cloudy weather should also be taken into account to dampen the air, and the air release time should be shortened. When the plant grows to 25 to 30 cm high, it can be fertilized once, applied urea, and watered immediately. After the plant enters a vigorous growth period, it must not be deprived of water. About 7 to 10 days, it should be poured with water. The water should be top-dressed once. The watering should generally be performed on a sunny morning. And spraying the plants with strong stems and stalks makes the seedlings flourish, the stems are thick, and the leaves are hypertrophic. At the same time, it is necessary to warm up the greenhouse seals so that the ground temperature can quickly rise and release the wind at noon. During the vigorous growth period, fertilizers should be applied in a timely manner, and thermal insulation and organic fertilizers should be applied to ensure the supply of trace elements. In the middle and late stages of growth, potassium dihydrogen phosphate and plant electronic fertilizers can be sprayed. And pay attention to the prevention of pests and diseases, and timely use of targeted drugs for effective prevention and control.
