The invention discloses a family balcony-assembled stereoscopic cultivation fungus and vegetable symbiotic system which comprises an edible fungus growth system, a vegetable cultivation system, a water-fertilizer control system and an assembled cultivation frame, wherein the vegetable cultivation system is arranged on the edible fungus growth system; the edible fungus growth system is arranged on the assembled cultivation frame; and the water-fertilizer control system is connected with the vegetable cultivation system to provide the vegetable cultivation system with nutrients. The family balcony-assembled stereoscopic cultivation fungus and vegetable symbiotic system can be provided with one or more edible fungus cultivation boxes and substrate cultivation troughs according to the size of a balcony, and the space of the balcony can be relatively well utilized; and meanwhile, edible fungi and vegetables can be planted, the edible fungi require sufficient fresh air in the growth stage, carbon dioxide is required for growth of the vegetables, and the vegetable cultivation system and the edible fungus growth system are arranged together, so that a small ecological cycle is formed by the vegetables and the edible fungi, and growth of the vegetables and the edible fungi is facilitated.
