Management measures, such as the case of storm sunny days after planting, at noon to be shaded 2 to 3 days, after planting should be preserved seedlings, can be watered 2 or 3 times. After easing the seedlings, deep cultivator and appropriate seedlings are used. In late October, when the minimum temperature dropped to 5°C, attention should be paid to the insulation at night, and the air should be cooled and humidified during the day to prevent the plants from becoming long and ill. The daytime temperature should be kept at 20°C~25°C and kept at about 10°C during the night. In mid-November, straw insulation should be stamped and the air should be kept for more than 2 hours every day. During cloudy days, it is also necessary to pay attention to air release and dehumidification, and the air release time should be shortened. When the plants are 25 to 30 centimeters in height, they can be fertilized once, and 20 kilos of urea can be applied. Water is then applied. After the plant enters a vigorous growth period, it must be water-repellent, and water should be poured once every 7 to 10 days. The water should be topdressed once, and the watering should generally be performed on a sunny morning. At the same time warming up the greenhouse seal, the ground temperature can quickly rise, let off at noon to eliminate moisture. The shortage of nitrogen or low temperature in the vigorous growth of celery can easily lead to hollow stems, boron deficiency prone to stem stalks, calcium deficiency may occur black heart disease, etc., so it should be timely watering, top dressing, insulation and apply more organic fertilizer to ensure trace elements The supply can be sprayed with 0.3% potassium dihydrogen phosphate or urea solution in the middle and late stages of growth. Timely Harvest When the plant grows to standard height, it can be harvested, generally from late December to early February, the growth period can not be too long, too long will lead to hollow, quality decline.
