At noon on a sunny day, the shed film was uncovered and the air was ventilated to reduce the humidity. Before planting ridges, pour watered manure 2 or 3 times. After ridge sealing, apply urea solution once.

V. Prevention of pests and diseases. In the seedling stage of celery, new high fat film is sprayed to prevent the occurrence of disease. In winter, after the insulation of the shed, the fumigation is used to control pests and diseases, and the effect is good.
