How to water and fertilize celery in greenhouse?
How should celery be watered and fertilized in greenhouse? Nitrogen deficiency in celery not only hinders the growth of the plant, the leaf is small, but also the petiole is prone to hollow. Phosphorus deficiency in the early stage and potassium deficiency in the later stage had great effects on the yield and quality of celery. Celery is very sensitive to boron fertilizer, and stem cracking occurs when boron deficiency occurs. Celery in greenhouse should be watered and fertilized scientifically to improve its yield and quality. The small water was watered frequently at the seedling stage. When the celery sprouts top soil, gently water once, 1-2 days seedlings can come out. In the future, keep the soil moist and water a small amount frequently. If the watering amount is too large, the seedlings are prone to overgrowth or rotten seedlings. When the height of the seedling is nearly 10 cm, it can be fertilized with water for 1 or 2 times. Squatting seedlings were carried out after planting slow seedlings. Planting to slow seedlings should be watered frequently and gently to keep the soil moist. After slowing down the seedling, the plant begins to grow, and the amount of water should be controlled and the middle tillage should be carried out to promote the root down and accelerate the differentiation of the heart leaf. If the moisture is too large, the outer leaves are easy to grow, the leaf center is not developed, and diseases are easy to occur. Increase the amount of fertilizer during the vegetative growth period. After the end of squatting seedlings, the growth of plants began to accelerate, quick-acting nitrogen fertilizer should be applied immediately, and potash fertilizer should be applied twice in stages. Generally irrigate every 3-4 days, the amount of irrigation can be less, so that the ground temperature is too low is not conducive to petiole hypertrophy. About half a month before harvest, the whole plant could be sprayed with gibberellin 30 mg / kg twice. More celery planting techniques
