Temperature and humidity management. When celery is raised, the mulch and the greenhouse should be covered with heat, and the mulch should be removed in time after emergence. As the temperature rises, the shed film is taken early to increase ventilation. Or change to cover with net and membrane, and build a small arch shed with four sides of ventilation and rain.
Fertilizer management. Pay attention to watering during seedlings to keep the soil moist. Watering should be done with small water. Morning and evening. And after applying the urea water to the seedlings, it can also spray the photosynthetic nutrient film fertilizer to help the plants absorb a large amount of light fertilizer, light energy, light, compatible with conventional fertilizers and nutrients to supply plant growth and development to the limit.
In addition to the grass field Miao Dingmiao. Before emergence, you can use the targeted agent + new high-fat film to evenly spray the surface to prevent seedling damage. When the seedlings have two true leaves, the seedlings are planted, and the seedlings are 1 cm apart. Watering should be done in time after the seedlings. When the seedling height is 10 cm, the planting is carried out. After planting, the seedling water is poured in time and a new high-fat film is sprayed to promote growth, and the slow seedling period is shortened.
