Celery is one of the favorite green leafy vegetables. Celery is rich in calcium, phosphorus, iron and protein, carotene, apigenin, vitamin C and other nutrients. It has high blood pressure, hardening of the arteries and neurasthenia. Such diseases have a good effect.
Celery requires a lot of nutrients in the growth process, so the soil should be rich in fertilizer to meet the nutrient requirements of celery. At the same time, because the root absorption capacity of celery is weak, the topdressing should be small. In the cultivation process, in addition to applying the base fertilizer, celery needs to apply a large amount of nitrogen fertilizer, but it is not allowed to use urea, because the urea is applied to make the celery plant aging, the fiber increases, and the bitter taste is produced. Production practice has proved that the application of nitrogen fertilizer to celery should be based on ammonium bicarbonate or freshwater manure. After topdressing, the plants can be tender, the fiber is reduced, and the quality is improved.

Hydroponics is a subset of hydroculture, the method of growing plants without soil, using mineral nutrient solutions in a water solvent. Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. The nutrients in hydroponics can come from an array of different sources; these can include but are not limited to waste from fish waste, duck manure, or normal nutrients.
