The first is small watering of seedlings. When the celery sprouts top soil, lightly pour water once and spray a new high-fat film, and the seedlings will be ready in 1-2 days. After that, keep the soil moist and irrigate a small amount. If the amount of watering is too large, the seedlings are prone to overlength or rotten seedlings. When the seedling is nearly 10 cm high, it can be topdressed with water 1-2 times. The second is to squat seedlings after planting. Hard and light irrigation keeps the soil moist, promotes the roots to ligate, and accelerates heart leaf differentiation. If the water is too large, the outer leaves tend to grow too long, and the leaf heart is underdeveloped, which is prone to disease. The third is to increase the amount of fertilization during the vegetative period. Immediately after the squatting seedlings are topdressed, fast-acting nitrogen fertilizer is applied, and potassium fertilizer is applied 1-2 times and sprayed with vegetables. This can activate positive energy for ecological growth of plants, widen the path of plant ducts, increase the capacity of plants to absorb water and fertilizer, and increase yield. And quality.
