Method of irrigation

FIELD: agriculture.

SUBSTANCE: invention relates to reclamation and can be used for irrigation of greenhouse and other agricultural crops. The method of irrigation is carried out by automatic periodic flooding. Water is formed by condensation of vapour in the pressure tank. Part of the time the tank is filled to the desired level, and then opens and actuates.

The invention relates to the reclamation and can be used for irrigation of greenhouse and other crops.

A device for sub-surface irrigation [1], in which the subsurface fill is placed in the trough-shaped groove in the head which has a device for automatic maintenance level. The disadvantage of this technical solution are:

- large water discharges;

- relatively high cost because of the larger amount of material.

The closest technical solution is a device for sub-surface irrigation [2], in which the subsurface fill is a perforated tube. The disadvantage of this technical solution are:

- lack of automation in the process;

- there is no possibility to use any water from any harmful components and salts.

The purpose of the invention - improving irrigation efficiency with simultaneous purification of water from salts and space heating greenhouses.

This objective is achieved in that the method includes irrigation subsurface irrigation, and irrigation is carried out automatically by periodic water inlets formed by condensation of steam in the pressure tank, which is part of the time is filled to the desired level, and after opening what is and is triggered as the humidifier is used perforated tube with holes, which are installed vertically at the place of root mass of the plants and the water in it comes from the droppings that are attached to the distribution pipe, the pressure tank while attached to the cooling radiator for heating the greenhouse with simultaneous cooling and condensation of the steam.

In the steam boiler has a mouth through which is filled with water, after which it is brought to the boil. The water in the steam boiler is brought to the boil over a Bunsen burner.

Plant water moves through the subsurface fill, representing a perforated tube which is installed vertically at the place of root mass of the plants, and the water in it comes from the droppings, which are fixed on a distribution pipeline (figure 1). The dispenser is connected to the pressure pipe. In the discharge pipe, water flows from the pressure tank.

Water in the pressure tank is formed by condensation of steam supplied from a steam boiler and may be regulated by valve. In perforated tubes are holes from which water enters the root system of plants.

Inside the pressure tank has a float regulator, which ensures its automatic operation. Pople who wkowy controller consists of a shaft attached: lower focus, and on top of the float. The up and down movements of the float regulator is on the rail. The emphasis falls into the conical head and closes the intake inlets in fluid piping (figure 4). In the event of rising water level in the tank the float raises the float regulator, and opens the pressure line (figure 5). Water enters the distribution and through a drip in the perforated tube (figure 4). After depletion of the pressure tank float regulator is omitted and emphasis overlaps the conical tip. Pressure tank while attached to the cooling radiator for heating the greenhouse with simultaneous cooling and condensation of the steam. The cooler is a metal plate with air layers.

Thus, the work tank and humidifying the root mass of the plant is periodic overlaps.

On the wall of a steam boiler is fixed with a screw and nut through the valve spring pressure of the boiler (figure 2). Spring with washer gasket, it closes or opens holes in the wall of a steam boiler.

As the heat generator can be used with gas or electricity. The perforated tube can serve as a base to which is attached the stem of the plant.

Method of irrigation in which allows water quality to use any water containing any number of salts.

Method of irrigation can reduce water consumption for irrigation in connection with the reduction of water losses due to evaporation. Does not form a crust on the soil surface, which improves the conditions for admission of air into the root mass. The greatest effect can be achieved under irrigation in greenhouses, as simultaneously heated the room.
