Description

A ventilation unit for vegetable greenhouse Technical Field The utility model relates to the technical field of greenhouse planting, in particular to a ventilation device for a vegetable greenhouse. Background Many large-scale cultivation methods, such as planting flowers, vegetables and the like, are carried out in a greenhouse, and it is known that plants such as flowers, vegetables and the like grow in a well-ventilated environment, while the greenhouse is a relatively closed environment, air in the greenhouse needs to circulate with outside air, and the circulation is called ventilation, and particularly, a mechanical or natural method is used for supplying enough fresh air into an indoor space, and simultaneously discharging dirty air which does not meet the sanitary requirement in the indoor space, so that the indoor air meets the sanitary requirement and the production process requirement.
