Plant cultivation system and control method of plant cultivation box

The invention discloses a plant cultivation system and a control method of a plant cultivation box. The control method comprises the following steps: controlling an illumination state of a light source module of a plant cultivation box according to a first growth parameter in a plurality of groups of growth parameters, wherein the first growth parameter corresponds to a growth condition needed by a cultivated object in a current growth stage; obtaining growth images of the cultivated object and illumination conditions in the cultivation space; analyzing the growth change degree of the cultivated object based on the growth images, and judging whether the growth change degree of the cultivated object in the first preset time accords with a preset rule or not; if yes, judging that the cultivated object enters a next growth stage, and selecing growth parameters matched with the next growth stage of the cultivated object from the multiple sets of growth parameters; adjusting the illumination state of the light sou
