Dyeing reagent-saving staining control method and system for slide stainer

The invention discloses a slide stainer staining control method and system capable of saving staining reagents. Comprising the following steps: uniformly distributing a staining agent into n staining jars, and sequentially soaking each slide rack in a first group of y slide racks which are used for bearing slides and are stained with other staining agents into the n staining jars from front to back for staining; after the number of the dyed slide racks reaches y in the a < th > group, liquid of the dyeing cylinder arranged at the first position at the moment is changed, and the position of the dyeing cylinder arranged at the first position at the moment and the position of the nearest dyeing cylinder which is not changed behind the dyeing cylinder arranged at the first position at the moment are changed; and then continuously soaking each slide rack in the (a + 1) th group of y slide racks in the n staining jars of which the positions are replaced from front to back in sequence for staining, and repeating the
