The general field is set at 2520 cm and the individual plants are planted. The depth of colonization is to expose the heart to the degree.
4. Field management: After easing seedlings, irrigation should be controlled to promote root growth. The first topdressing is dominated by nitrogen fertilizer, urea is 8-10 kg/mu, when seedling height is 25 cm, secondary fertilizer is applied, urea is 12-15 kg/mu, and when seedling height is 35-40 cm, the third top dressing is performed. Urea is available. 20 kg.
5. Pest Control: The disease of celery is spot blotch and spot disease. It can be soaked with warm soup or sterilized with pesticides. Drain well, improve ventilation and light transmission conditions, remove diseased leaves, and spray Bordeaux mixture or 50% dexamethasone at the early stage of disease. 1000 times liquid control, insect pests are mainly aphids, can be used dimethoate control.
