1. Seedling stage When the celery buds top the soil, lightly water the water once, and the seedlings can be 1-2 days. After that, keep the soil moist and a small amount of water. If the amount of water is too large, the seedlings are prone to appear lengthy or rotten. When the seedling height is nearly 10 cm, it can be topdressed with water 1-2 times.
2, planting seedlings Planting to slow seedlings should be poured, lightly poured to keep the soil moist. After the seedlings are slowed down, the plants begin to grow. The amount of water should be controlled and cultivating should be carried out to promote the roots under the roots and accelerate the differentiation of the heart leaves. If the water is too large, the outer leaves are long, and the leaf heart is not developed, which is prone to disease.
3, vegetative growth period After the end of the seedlings, the plant began to accelerate growth, should immediately apply rapid-acting nitrogen fertilizer, after the staged application of 1-2 times potassium fertilizer. Generally, water is poured once every 3-4 days, and the amount of irrigation can be less, so as to avoid the ground temperature being too low, which is not conducive to the petiole hypertrophy. In the first half of the harvest, the whole plant can spray 30-50 mg/kg gibberellin 1-2 times, and the yield increase effect is remarkable.
Watering and fertilizing celery in greenhouse
Nitrogen deficiency in celery not only hinders plant growth, leaves are small, and the petiole is prone to hollowness. Phosphorus deficiency in the early stage, the late potassium deficiency has a greater impact on the yield and quality of celery. Celery is very sensitive to the reaction of boron fertilizer, and it will appear in the absence of boron. Celery in greenhouse should be watered and fertilized scientifically to improve the yield and quality of celery.
