The invention discloses a semi-underground greenhouse special for edible mushroom cultivation. The semi-underground greenhouse comprises wall bodies on both sides, and a ceiling, and is characterized by further comprising vent pipes arranged on the wall bodies on both sides, and micro-jet humidification systems reversely hung on the ceiling, wherein the ceiling is covered with a heat-insulating curtain; the heat-insulating curtain comprises an EVA (Ethylene-Vinyl Acetate) three-proofing film, a heat-insulating quilt and a black water-proof film which are arranged in sequence from inside to outside; the ceiling is provided with an electric embedded ventilation window and a matched side-placed curtain rolling machine; the ridge of the greenhouse is oriented north and south; the ground in the greenhouse is lower than the ground outside the greenhouse; and an enclosed buffering chamber is formed outside a door of the greenhouse. The semi-underground greenhouse has the beneficial effects that adjustment can be performed by using the vent pipes, the ventilation window and the humidification systems according to different temperature and humidity demands in a mushroom emerging period, so that the temperature difference in the whole greenhouse is small, the humidity is moderate, good ventilation is realized, and edible mushroom cultivation is facilitated. In the greenhouse, the curtain rolling machine can be adjusted to control the amount of incoming light according to the sunlight demands of different kinds of edible mushrooms. The semi-underground greenhouse has a good use effect and high practicability.
