FIELD: agriculture. ^ SUBSTANCE: invention refers to the sphere of agriculture and deals with growing agricultural plants in greenhouses. The suggested aeration system intended for heating and moistening the air, and heating, moistening and aerating the soil inside a solar greenhouse consists of a glazed frame, a soil medium and a subsurface aeration system equipped with perforated air and water pipe ducts. The hydraulic motor is connected via a spindle to the water pump. The liquid-gas ejector is connected to the solar greenhouse air exhaust line. The valves and the separator are connected to the input of one of the valves via air pipe duct. The valve output is connected to the greenhouse. The water pump output is connected to the input water nozzle of the liquid-gas ejector whose output is connected to the separator. The air pump duct is connected to the generator of negative-charged ions, with the gravel layer inside the greenhouse - via the second valve whose drive is connected to the control unit. The third valve output is connected to the input of the perforated air pipe duct via a washer plate. The third valve drive is connected to the soil moisture monitoring and control unit connected to a pressure gauge. ^ EFFECT: improving the quality of heating and moistening the air and heating, moistening and aerating the soil inside a solar greenhouse. ^ 1 dwg |
