The invention discloses an agricultural planting technology of high and new technologies, and particularly relates to an industrial breeding method for celery seedlings. The invention creates the similar space, temperature and lighting conditions required for the plants by using the growth characteristics that the temperature required for celery seed breeding is 15 DEG C to 20 DEG C, and the celeries have shallow roots, and the reasonable soil nutrition is required and the moisture demand is met during the breeding process, and a germinating and sprouting method for the celery seeds is adoptedby selection, creation and seedling raising to the celery factory; and a celery seedling nutrition bed is utilized, the industrial cultivation and management to the celery seedlings are carried out to obtain celery seedlings cultivated at a large scale, and the celery seedlings are supplied by a factory method to meet the demands to the celeries for agricultural planting.
