Greenhouse celery should be scientifically watered and fertilized

First, the small water in the seedling stage is poured. When the celery buds top the soil, lightly water once, and 1-2 days of seedlings can be released. 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. The second is to carry out seedlings after planting the seedlings. Diligent pouring and light pouring keep the soil moist, promote the roots to sag, and accelerate the differentiation of heart leaves. If the water is too large, the outer leaves are prone to be long, and the leaf heart is not developed, which is prone to disease. The third is to increase the amount of fertilizer applied during the vegetative growth period. After the end of the seedlings, the quick-acting nitrogen fertilizer should be applied immediately, and the potash fertilizer should be applied 1-2 times in stages. 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.
