FIELD: agriculture.SUBSTANCE: greenhouse includes a frame with elements for fastening the frame on the earth surface and a covering web installed thereon. The covering web is made in the form of a cover embracing the greenhouse frame of prefabricated elements, each of which is made in the form of a plate with a groove with openings at the edges of the plates for their connection with each other, formed at the center along the length of the prefabricated element. A door is made in one end side of the cover, and an air vent - on the other side of the cover end. The contours of the door and the air vent are made in the form of slits in the cover material. The sides of the slits are connected to each other by means of connecting means. In the cover opposite the grooves of the prefabricated elements, in the extreme arcs and racks of the greenhouse frame and in the central part of the cover, at least three transverse channels are formed for passing a cord in them, which tightens the cover to the frame.EFFECT: green
