Known blagoukrasheniem soil structure (Smagin AV and other Vagoaccessorius soil structures: theory, experiment, practice // agro-ecological problems of soil condition of non-Chernozem zone and their solutions. - M.: Moscow state University, 2009. - Pp.118-130).

In the proposed structures as blagoukrasiteli funds uses of soil conditioners natural origin: peat, manure, compost, lime, humates. To achieve maximum efficiency in the use of these soil materials is recommended to place them in separate layers. To prevent irrigation water loss by deep percolation was used fluvioglacial sand, gravelly coarse material with an average diameter of 1 to 3 cm, peat, have a layer thickness of 5 cm at depths of 5-10 cm, 25-30 cm, 35-40 see

The disadvantage of the proposed structures is not used in the irrigation furrow.

The irrigation system comprises a main discharge pipe, additional pressure pipelines, distribution of pipeline the odes, tiers irrigation pipes connected to the distribution piping, the software device control discrete irrigation, closures on additional pressure pipelines, hydraulic drives which are connected to the outputs of the software of the device.

The lack of irrigation systems is its high cost associated with the large number of irrigation pipes, erosion of soil by watering due to strip irrigation furrows on the maximum slope.

There is a method of soil moisture in mountain-foothill area under irrigation plots furrow livestock effluent and system for its implementation (patent for invention 2400058 EN, IPC A01G 25/00 / Kim I.A., Terpigorev A.A., I.I. Kim, Kim A.I. - Publ. 27.09.2010. - Bull. No. 27. - 7 S.) prototype.

The system contains a source of irrigation, samonabornye the pipeline laid on the maximum slope, the automated control system. To samonabornye pipeline through a valve with diaphragm actuator connected irrigation piping with microkeratome to supply water to a group of compacted dead-end furrows, part of the upper part of which is laid at an angle to the contours of the terrain, and the lower part is parallel to the contour lines. Method soil moisture carry out discrete irrigation technology with variable supplies the house irrigation jets and dispersal of issuance of irrigation norms.

The disadvantage of the system and method of soil moisture are the possible loss of irrigation water to deep percolation and overflow irrigation furrows and water discharge, uneven soil moisture along the length of irrigation furrows.

The technical result of the claimed invention is to improve the uniformity of soil moisture, the moisture content of the active layer of the soil, preventing water losses to deep percolation, water discharge at the end of the irrigation furrows.

The claimed result is achieved by the fact that the system of land reclamation at discrete irrigation furrow, includes a source of irrigation water intake connected to clonapine pipeline, through which the butterfly valve with diaphragm actuator is connected to a pair of distribution pipes. The outputs of the distribution pipes connected with irrigation pipelines laid on the maximum slope. Irrigated areas contain dense irrigation furrows laid on the edges of the beds. The upper part of the irrigation furrows are laid with a small slope at an angle to the contours of the terrain, and the lower part, made in the form of a deep irrigation ditch runs parallel to the contour lines, connected at the end with the same furrow irrigated from another irrigation pipeline. On the irrigation pipeline installed the stepper hydrauli the mini-engines, associated with ball distribution valve, the outputs of which are connected by pipes with distributing grooves, through which water is supplied in a pair of tight irrigation furrows. In the middle of the beds padded trench depth up to one meter, filled with peat and manure. The center of the beds covered with a mulch of crop residues below the irrigation furrows laid the screens of reclamation film, above which the active layer of soil seedbeds padded layer (5...10 cm) of sand or gravel, the thickness of which increases when approaching the end of the upper part of the irrigation furrows.

The control unit irrigation contains the power supply, controller, electronic keys, electrohydraulic a receiving device and connected with the membrane drives the gates, and in place of the coupling of the two control irrigation furrows, pour two neighboring irrigation pipes, a gas sensor control seeking irrigation streams connected to the alarm device.

The duration of the pulse is determined by the control sensor is seeking the irrigation stream. At the beginning of the issuance of irrigation norms pulses irrigation serves alternately in four pairs of irrigation furrows. After stabilization time seeking irrigation jets until the end of the irrigation furrows cyclic applying pulses of irrigation in four pairs of irrigation furrows stops. The remaining hour is irrigation norms is a cyclical pulse irrigation in four pairs of irrigation furrows with the increase of the pause between pulses depending on water-physical properties of the soil up to 24 hours.

The reclamation system at discrete irrigation furrow prevents unproductive losses of irrigation water to deep percolation, reset, to improve the uniformity of soil moisture along the length of irrigation furrows.

The ends of the irrigation furrows are connected with the same ends irrigation furrows irrigated from another irrigation pipe 7. In the middle of the beds 12 padded trench 13 a depth of one meter, filled with peat and manure. The center of the beds 12 are covered with mulch 14 from plant residues. Below irrigation furrows laid the screens of reclamation film 15 above which the active layer of soil seedbeds padded layer (5...10 cm) of sand or gravel 16, the thickness of which increases when approaching the end of the initial part of the irrigation furrows.

In place of the coupling of the two control irrigation furrows 11, pour two neighboring irrigation pipes 7, a sensor 17 seeking control of irrigation streams connected to the alarm device 18.

The alarm device 18 includes a power source, a radio transmitter, a device control circuit contacts of the sensor 17 of seeking control of the irrigation stream.

The reclamation system at discrete irrigation furrow works as follows.

If the purpose of irrigation in unit 5 controls introduced irrigation rate. After a start block 5 controls delivers the water pressure on the diaphragm actuator of the shutter 4 of the first distribution pipe 6 and at the and of the first drip line 7 is fed to the first pair of compacted irrigation furrows 11, pour from the first drip line 7.

After seeking the spray jets to the sensor control seeking irrigation jets alarm device sends a radio signal received by the unit 5 controls, which sends the command to close the shutter 4 of the first irrigation pipeline and the opening of the shutter 4 of the second junction 6 of the pipeline. Water from the second irrigation pipe 7 is fed to the first pair of compacted irrigation furrows 11. The controller unit 5 management Strait remembers the pulse duration of irrigation.

During the pulse irrigation drains of the first pairs watered irrigation furrows 11 watered end parts of the second pairs of irrigation furrows 11, pour from the second irrigation pipe 7. After seeking the spray jets to dock irrigation furrows 11 sensor control seeking irrigation jets he gives the signal. Unit 5 controls gives a command for termination of irrigation second irrigation pipe and start watering from the first irrigation pipeline. In the process of lowering and re-increasing the pressure in the irrigation pipe hydraulic stepper motors 8 switch ball valve in the second position, and water is supplied to the second pair of irrigation furrows. The pulse duration corresponds to the stored pin is the Oller pulse irrigation, the corresponding pulse duration when water in the first couple of irrigation furrows 11. Similarly implemented watering all four pairs of irrigation furrows.

In subsequent rounds irrigation controller compares the pulse duration of watering when watering the first pairs of irrigation furrows. When reducing this difference to a predetermined setpoint, the controller determines whether termination of the cycle of the circular pulse supply irrigation and then increases a pause, depending on water-physical properties of irrigated soils, between cycles of the pulse supply from 12 to 24 hours.
