FIELD: agriculture.
SUBSTANCE: system comprises a source of irrigation, a dam, water overshot wheel, a water intake device in the form of a mesh scouring cylinder, a liquid-gas ejector and a water pump, generators of air ions and ozone, a reservoir with manure, a subsoil system of moistening and aeration of soil in the greenhouse, a unit of soil humidity control. A mesh scouring cylinder is installed inside the water overshot wheel. Inside the scouring cylinder a waste chute is located with a perforated pipeline. The perforated pipeline is connected through the gate to the inlet of the circulating-water intake. The outlet of the circulating-water intake is connected through the gate to the input of the water pump. The water wheel shaft is connected through the reducer to the water overshot wheel. The outlet of the water pump is connected to a water pipe of the liquid-gas ejector. The ejector air nozzle is connected through the gates to the generators of air ions and ozone, the atmosphere, the reservoir with manure. The reservoir with manure is connected through the gates with the generators of air ions and ozone. The output of the liquid-gas ejector is connected to the conductive pipeline. The conductive pipeline is connected to the perforated irrigation pipelines. The perforated irrigation pipelines are mounted under the trenches filled with manure. The trenches are located in the middle of the beds covered with film tunnels. Above the beds the greenhouse is placed. In the active layer of the soil of the greenhouse a capacitance sensor of integrated humidity of soil horizon is placed. The sensor is made in the form of two parallel metal strips. Between the parallel metal strips a layer of porous ceramic is laid, connected to the unit of soil humidity control.
EFFECT: design enables to improve the quality of moistening, aeration and heating the active layer of soil in the greenhouse.
