Celery needs to apply a large amount of nitrogen fertilizer throughout the growing season, but urea cannot be applied. Because after the application of urea, the celery fiber will increase and become thicker, the plant will be aging, the growth will be slow, and the taste will be bitter and the quality will be inferior. It is advisable to use ammonium bicarbonate, ammonia water and organic fertilizer for fertilizing celery, which is conducive to improving quality.
