Celery suitable for more nitrogen fertilizer, but not topdressing urea. Celery requires a large amount of nitrogen fertilizer throughout the growth period, and top dressing is mainly ammonium bicarbonate. To do a small number of times, usually need to fertilizer 2-3 times. However, it should be noted that celery should not be topdressed with urea, because growth of celery followed by urea is slow but with more cellulose, the plants tend to age, the quality is reduced, and they are bitter when consumed. Topdressing organic fertilizer can improve the quality of celery. The top-dressing chickens, ducks and other domestic poultry organic fertilizers are applied to the plant. The celery plants are thick and soft, and the fibers are reduced. The quality and yield are greatly improved. However, no mature farm organic fertilizer can be used as top dressing, so as not to cause burning rot. Supplementary application of fertilizer, can prevent celery physiological diseases. Calcium deficiency will cause celery to "burn heart", and boron deficiency will cause celery hollow, petiole crack and other physiological diseases. Foliar application of 0.5% calcium chloride or calcium nitrate solution can prevent celery "burn heart." To prevent cracking of the celery hollow and petiole, 0.5-0.75 kg of borax can be applied per mu, or sprayed with a 0.3%-0.5% borax solution.
