The invention relates to agriculture and can be used for irrigation of agricultural crops in the mountain foothills.

Known vortex water activator (Andreev Y. Water - the vicar of God on earth. - SPb.: Peter, 2007. - 320 S.), made in the form of Aquatica (p.50), translingo amplifier vortex Flanagan (pp. 102-103)using the device to activate the water swirling motion of the water. Vortex water activator can be used to improve crop yields. The lack of application of the activator water is not used in clonapine irrigation systems.

Known automated sprinkling machine circular steps (Patent for invention 2048066 (RU), MKI6A01G 25/09 / Apennin, Npomodul, Ajaculation, Vmenu, Vasilchenko. - Publ. 20.11.1995). The machine provides full automation controls through direct control of soil moisture by tensiometers installed at the control sites in the rooting zone of the soil, and their inclusion in the control system of irrigation, thereby linking her on and off the machine directly with soil moisture.

The disadvantage of applied automated system controls the definition of tensiometers soil moisture at the point, without regard to distributed what I moisture in the active layer of soil and its integral value, which reduces the accuracy of controls and does not completely eliminate the loss of irrigation water to deep percolation.

In addition, this system controls required periodic calibration of sensors due to changes in water-physical properties of soil during irrigation period.

Known system telemetry remote automated control of irrigation systems (Use of telemetry remote automated control of irrigation systems // Express-information, cbti the Ministry of water resources of the USSR. - M., 1989. - Vol. "Irrigation and water management abroad". - VIP. - C.1-3). The system contains the Central manor farm personal computer. Through the management of all sprinkler machines, and in his memory and magnetic disks accumulate all the data of the transmitted commands and system operation. For transmission and reception of information at the Central farm and on each managed from the center pivot are the microprocessor, a modem, a radio transmitter with an antenna. Machine or mechanism is equipped with sensors for reading information from the system pressure, level sensors, pressure transducers, thermometers, anemometers, and so on, depending on the capabilities of the farmer and the required accuracy obtained is the results.

The disadvantage of this system is the lack of control of discrete irrigation furrow and controls on the detector end of the irrigation to prevent irrigation water loss by deep percolation.

Known information-advising system (ASCS) irrigation management // Express-information, cbti the Ministry of water resources of the USSR. - M., 1988. - Vol. "Irrigation and water management abroad". - VIP. - P.1-6).

To determine the optimum amount of water to water users provided the following information about the irrigation mode:

- maximum irrigation rate is determined on the basis of soil characteristics and morphology of cultivated crops;

- optimal timing of irrigation, determined for each culture and each farm by the equation of water balance.

Daily counts of the income and expenditure of the water balance is determined by the moisture deficit in the soil. The timing of irrigation are appointed by the cumulative moisture deficiency in the soil. Potential evapotranspiration is determined according to the testimony of evaporators.

Collect baseline data on precipitation, irrigation, the depth of the ground water are the water users.

When watering between water users and ASCS to operationalize the link.

The disadvantages of the system are the lack of controls on the sensors soil moisture is, that reduces the quality controls, the lack of control pulse irrigation furrow.

Known automated control system of irrigation by furrows of closed irrigation network managed microkeratome (Kim I.A. Automated control system of irrigation by furrows of closed irrigation network managed microkeratome // automation of water distribution in irrigation systems. Frunze: Ilim, 1987. - S.138-142).

Irrigation network contains samonabornye the pipeline laid on the maximum slope that is connected to the irrigation pipelines managed underground microkeratome to supply water in the furrow laid under the top layer, along the contours of the terrain.

Automated control system of irrigation has a Central control unit (CPU)installed in the center of the irrigation system, connected by communication lines with remote control (PU), dened on the nodes of the irrigation network.

The CPU contains the modem, the software device control pulse irrigation and electronic keys for supplying control pulses to the line four pulsed electrohydraulic which are in each PU. The input pulse electrohydraulic connected with clonapine the pipeline, and outputs four the logging control with four groups of underground microhydrated.

The disadvantages of an automated irrigation system are:

- strip irrigation furrows on the maximum slope that causes irrigation in the foothills on large and medium slopes significant soil erosion;

- not fully eliminated the discharge of irrigation water at the end of the irrigation furrows;

- the distance between the irrigation furrows is 0.6-0.7 m), which determines the need to install a large number of microhydrated;

- the location of microhydrated under arable layer causes large difficulties for their replacement, repair and elimination of impurities of microhydrated;

the high cost of irrigation systems due to the need for installation of underground irrigation pipes and a large number of managed microhydrated;

- low coefficient of irrigation systems, as irrigation is performed alternately and only one tier, containing two irrigation pipeline prior to the issuance of irrigation norms, and other irrigation pipelines at this time not used;

- lack of coordination of the work of the irrigation system with other irrigation systems irrigation array.

Known way to control furrow pulse irrigation (A.S. 1528392 (USSR), MKI4A01G 25/16 / Sci - Iaim. - Publ. 15.12.89. Bulletin no. 46).

The control method includes measuring noController site settings in the upper and lower horizon of the active layer of soil, associated with its humidity, the purpose of irrigation groups of sites norms on the hydration of all the active soil layer or upper layer depending on the comparison result of the difference of the measured parameters before and after irrigation parameter values of the upper and lower horizons of the active layer of soil with a permissible value. The end of the irrigation groups of sites assigned with decreasing values of the identified differences humidity values of the upper and lower horizons of the active layer of the soil, to the set of valid values.

With the aim of improving the quality of irrigation while reducing the discharge of water watering is carried out cyclically fractional rate of irrigation with fractional ratio of irrigation to the norm on the hydration of the entire active layer of soil from 0.25 to 0.1. Irrigation by the hydration of the upper horizon of the active layer of the soil to produce alignment of the physical parameters of all active soil layer, measured after the previous irrigation norm on the hydration of the entire active layer of the soil. Irrigation by the hydration of the entire active layer of the soil is fractional irrigation norms, to align the physical parameters of the upper and lower horizons of the active layer of the soil, measured during irrigation. The second condition for the end of the irrigation is the convergence of the parameters of the lower horizon of the active layer of the soil, zmiennych immediately after the end of the previous irrigation norm on the hydration of the entire active layer of the soil and measured during the irrigation.

Each cycle of each group of sections hold variable rate irrigation sprays applied in furrow.

Consumption of irrigation jets first gradually increases to the maximum. After seeking the spray jets until the end of the furrow flow irrigation jets from cycle to cycle is reduced to provide a reset at the end of the furrow, do not exceed the permissible value.

The disadvantage of the method of controlling irrigation furrow is not a complete elimination of water losses to deep percolation and reset.

The technical result of the claimed invention is to improve the quality reclamation of irrigated plots in the Piedmont zone, elimination of losses of irrigation water to deep percolation and reset, increasing crop productivity, improving efficiency and reducing the cost of irrigation systems.

The claimed technical result is achieved by the fact that the system reclamation of irrigated area, located on the southern slopes in the Piedmont zone, contains each of the irrigation areas irrigation system having a first samonabornye pipeline, the inlet of which is connected to the intake structure, and the output to the input of the first gate and the input of the second gate at the entrance of the vortex water activator. The outputs of the first shutter and the vortex of water activator is connected to the input of the second samona REGO pipeline. In the irrigation network nodes to the second samonabornye pipeline connected to the inputs of the pulse electrohydraulic, the outputs of which are connected by a tube to the control group, connected with the pressure pipe, managed microhydrated.

Managed Microhydrin displayed on the stationary surface spaced ridges (crests) and are connected by tubes or grooves with the beginning of the four dead-end irrigation furrows. Irrigation furrows are laid along the edges of the ridges (crests), symmetrically on either side of the discharge pipe, at an angle to the contours of the terrain with a slope of not more than 0,005, and the distance between a dead-end irrigation furrows (1,8 1,2...) corresponds to the distance between the wheels used agricultural machinery. In the middle of the beds laid narrow trenches filled with plant residues and manure, which multiroute also on top of the litter.

Automated control system of irrigation on irrigated array contains measuring and computing system installed in the control plot irrigated area. Measuring and computing system connected to the anemometer sensor surface air temperature, relative humidity sensor surface air, rain gauge, temperature sensors in the active soil layer, the radio is haunted and radio transmitting device.

Irrigation systems irrigation plots established Central control unit (FCU), the inputs of which are connected to a radio receiver and detector end of the irrigation, and the outputs from radio transmitting device and wire line communication with control panels (CP) pulse electrohydraulic.

The detector end of the irrigation is made in the form of two integral sensors humidity soil layer, the first of which is inside the lower horizon of the active soil layer, and the second is at the lower border of the active layer of the soil.

The beginning of the cyclic pulse irrigation groups of irrigation furrows of parcel groups microhydrated irrigation system is determined by the information-Advisory system, coordinating the work of all irrigation systems irrigated area, and the CPU on the detector end of the irrigation.

The way reclamation of irrigated area in the foothills and system for its implementation will improve the quality reclamation of irrigated land in the foothill zone, crop productivity, efficiency irrigation systems and reduce the cost of the irrigation system.

The drawing shows the design of the drainage systems of the Piedmont area.

System reclamation of irrigated area in the Piedmont zone contains water intake structure 1 from the source Oro is placed 2. The output of the diversion structure is connected to the input of the first clonapine pipeline 3, the output of which is connected to the input of the first gate 4 and the input of the second gate 5 at the inlet of the vortex water activator 6. The outputs of the shutter 4 and vortex activator 6 is connected to the input of the second clonapine pipeline 7.

In the irrigation network nodes samonabornye pipe 7 is connected to the inputs of the pulse electrohydraulic 8, the outputs of which are connected by a tube control 9 with a group connected with the pressure pipe 7, managed microhydrated 10. Managed Microhydrin 10 displayed on the stationary surface spaced ridges (crests) 11 and are connected by tubes or grooves 12 with the beginning of the four dead-end irrigation furrows 13 and do not interfere with the passage of machinery for irrigation furrows. Dead-end irrigation furrows 13 laid on the edges of the ridges (crests) 11 symmetrically on either side of the discharge pipe 7 at an angle to the contours of the terrain with a slope of not more than 0,005, and the distance between a dead-end irrigation furrows (1,2...1.8 m) corresponds to the distance between the wheels used agricultural machinery. In the middle of the beds laid the narrow trench 14 is filled with plant residues and manure, which multiroute also on top of the litter.

The automated control system is possible irrigation on irrigated array contains measuring and computing system 15, mounted on the control plot irrigated area.

Measuring and computing system 15 contains computer peripheral devices, modem, interface and connected to the anemometer 16, the sensor surface air temperature 17, a relative humidity sensor surface air (psychrometer) 18, precipitation gage 19, the temperature sensors in the active soil layer 20, a receiver 21 and a radio transmitting devices 22.

Irrigation systems irrigation plots (control plot irrigation system) installed in the Central control units (CPU) 23, the input of which is connected to a receiving device 24 and the detector end of the irrigation 25, and the output from the radio transmitting device 26 and the two-wire line 27 with remote control (PU) 28 pulsed electrohydraulic 8.

The CPU 23 contains a battery, solar battery, modem, controller, ADC and DAC driver test signal applied to the humidity sensors of the detector end of the irrigation 25, electronic keys, the signal meter humidity sensors.

The detector end of the irrigation 25 made in the form of two integral sensors humidity soil layer, the first of which is inside the lower horizon of the active soil layer, and the second is at the lower border of the active layer of the soil. The sensors can be made is, for example, in the form of two twisted wires, laid horizontally across the irrigation furrows.

The distance between the sensors depends on water-physical properties of the active soil layer and must ensure the absorption of moisture coming from the upper layers of the soil after the issuance of the last pulse irrigation and moisture retention from its losses to deep percolation.

The control unit 24 pulsed electrohydraulic 4 contains a capacitor battery, rechargeable by a two-wire line 26, the pulse counter control, driver pulses to the switching pulse electrohydraulic 8, electronic keys for supply of control voltage pulses to the coil pulsed electrohydraulic 8 or relay pulse distributor control.

The method of land reclamation in the foothill zone is implemented as follows.

Autumn in the irrigated areas located on the southern slopes, is deposited manure, and then create a bed 11. In the middle of the beds 11 are narrow trench 14, which are filled with manure and crop residues and multiroute on top of the litter. In the narrow trench 14 run Californian worms. The edges of the patches 14 are dead-end irrigation furrows 13 laid together with beds at a small angle to the contours of the terrain to the slope of the furrows do not exceed what is 0.005.

Early spring on the leaves 11 are agricultural crops and a bed cover film tunnels. Plant residues and manure in the debate generate heat to heat the soil.

After raising the temperature to values sufficient to grow crops without plastic tunnels, film tunnels removed.

For all agricultural activities of agricultural machinery wheels only move on a dead-end irrigation furrows 13, condensing them, and not condense the active layer of the soil.

Cultivation irrigation furrows are made from the bottom up, to move washed away the soil up.

In autumn, after harvest, resulting in narrow trenches 14 vermicompost is removed to the surface of the beds, and the narrow trench 10 is again filled with manure and crop residues and multiroute on top of the litter. The following spring before planting, the soil at the edges of the beds 11, where they will be planted, only to riglits. Tillage is not possible.

Before irrigation, the irrigators in the irrigated plots reveal gates 4 and, if necessary, pour the activated water, open the gates 5.

The Manager enters in the computer measuring and computing system 15 program irrigation management irrigation plots characteristics of irrigated plots: soil moisture in the irrigated areas, the water content in the active layer of the soil, the lower boundary of the water content at which achievement is assigned watering sites, landing time and the types of crops planted in the irrigated areas, the biological factors of crops, types and parameters of irrigation systems in the irrigated plots, etc.

The operator then includes measuring and computing system.

The beginning of the irrigation areas is determined by measuring and computing system, coordinating the work of all irrigation systems irrigated area. The end of the irrigation irrigated land is determined by the CPU 23 of the irrigation system at the detector end of the irrigation of 25.

Measuring and computing system begins to produce a survey of the anemometer 16, temperature sensors 17 a relative humidity of 18 in the surface layer of air, rain gauge 19, the temperature sensors in the active soil layer 20 and calculates evapotranspiration in irrigated plots and calculates for a given program evapotranspiration in irrigated plots, calculates the income and expense components of the water balance.

With decreasing water content in the irrigated area to a predetermined lower boundary of the optimum soil moisture measuring and computing system 15 via the transmitting unit 22 transmits a signal receiving device 24, the CPU 23 at the beginning of irrigation. The CPU 23 defined the irrigated land is included in the work and submits it to the two-wire communication line 27 pulse of positive polarity 1 sec. to activate the first electrohydraulic 8. The pulse is fed to the input of the control device 28. The first control device 28 generates a pulse of positive polarity (+27) and 1 sec. to activate the first pulse of electrohydraulic 8, after which enable the water pressure in the tube control 9 served on a managed Microhydrin 10, which is opened, and the pulse irrigation is supplied to the first group of dead-end irrigation furrows 13.

The pulse duration of irrigation is set such as to ensure the seeking of irrigation jets until the end of a dead-end irrigation furrows, but there were no water discharge at the end of a dead-end irrigation furrows 9.

After issuing pulse irrigation, the CPU 23 generates a two-wire communication line 27 the next pulse of positive polarity. The first control device 28 generates a pulse of negative polarity (-6) duration 1 s, which is served on the first electrohydraulic 8, which is turned off, and the water in the first group of irrigation furrows terminated.

At the same time the second control device 28 generates a pulse of positive polarity, which includes the second electrohydraulic 8, and the pulse irrigation is supplied in the following group of irrigation furrows.

Similarly, you can alternate cyclic pulse of irrigation in all the groups dead-end irrigation furrows 13.

After the issuance of each is mpulse watering the CPU 23 in the control plot measures the readings of the detector end of the irrigation 24.

If the difference in the readings of the upper and lower sensors of the detector 25 to start and after issuing a pulse irrigation is changed to a predetermined setpoint, then it is a signal that the wetting front has reached the top of the soil moisture sensor. The CPU 23 after the grant of the next pulse irrigation in all groups irrigation furrow forms in two-wire communication line 27 pulse of negative polarity, which is for control devices 28 signal the end of the irrigation. This counters all control devices 28 are reset before the next watering.

Simultaneously, the CPU 23 transmits through the transmitting device 26, the signal measuring and computing system 15 about the end of the irrigation area, which captures outpoured irrigation rate, determines the start of the regular watering of the site and starts the calculation of evapotranspiration on the watered area. After evaporation of irrigation norms issued information-measuring system 15 signals the beginning of the next irrigation irrigated land.

In addition, information-measuring system 11 during the irrigation period coordinates on irrigated array of all irrigation systems to ensure stabilization of water supply to irrigated array, increasing the efficiency of irrigation systems.

When the accident at the irrigation system information-measuring with the stem 15 connects to irrigation other irrigation areas, with subsequent correction of irrigation norms, controls the conduction of water recharge and refreshing irrigation plots the forecast and the occurrence of air draughts.

The use of the method and system of land reclamation in the Piedmont area allows you to:

- to prevent water and wind erosion of soil;

- collect and save early spring moisture in the soil and reduce its loss by evaporation;

to provide an opportunity for early cultivation of organic agricultural products, get two crops, to make disposal of manure on the field;

to reduce the cost of tillage and weeding;

- to prevent compaction of the active layer of the soil by the wheels of agricultural equipment;

- to activate biological processes in the active layer of the soil;

- increase the yield of agricultural crops.

- no periodic calibration of sensors integrated soil moisture signaling the end of the irrigation;

- reduce the cost of irrigation systems due to the lack of irrigation system, irrigation pipes and increase the distance between the irrigation furrows;

to facilitate the work of irrigators and reduce C is expenditure on irrigation.

Location wide beds and irrigation furrows constantly in one place contributes to the formation of the beds and irrigation furrows. The process of irrigation is the deposition of sediments in depressions irrigation furrows and reduce roughness. Subsequent cultivation of irrigated furrows is micropedology of irrigated land, the formation of smooth irrigation furrows, so as to prevent flow of water from irrigation furrows through the crests of the beds in the nearby irrigation furrows.

Gasket grooves with small bias allows you to: apply in furrow irrigation streams with erosion valid flow irrigation stream more than 1 l/s, to increase the length of irrigation furrows and improve the quality of pulse irrigation.

The implementation of irrigation furrows dead-end furrows prevents the loss of irrigation water to discharge, increases the uniformity of soil moisture along the length of irrigation furrows with pulse irrigation.

The purpose of the beginning of the irrigation field irrigation command measuring and computing system and completion of irrigation on signaling the end of the irrigation allow:

- to stop watering until the moisture in the active layer of soil and keep filterable from the upper horizon of moisture in the lower horizon of the active layer of the soil;

to prevent its loss to deep percolation;

- to increase the efficiency of irrigation systems.

SUBSTANCE: apparatus has accumulation reservoir with bottom opening closed with valve, auxiliary reservoir, two float valves, one of said valves being designed for feeding water to accumulation reservoir and other valve serving for cutting-off said feeding process. Valve floats are positioned within auxiliary reservoir positioned lower than bottom of accumulating reservoir and connected through flexible pipelines to hermetically sealed reservoirs having porous bottoms and embedded in soil. Drawing of water by soil through said bottoms results in reduction of water level within auxiliary reservoir. Float valves are opened and water is delivered through one of said valves into accumulating reservoir. On reaching of predetermined water filling level, discharge opening valve is opened and water is delivered into low-pressure irrigation system and through other float valve into auxiliary reservoir. Increase in water level within accumulation reservoir cuts-off feeding of water into this reservoir. During operation of high-pressure irrigation system, functioning of apparatus is regulated by filling of accumulation reservoir to certain small volume and stabilized by means of detachable reservoir adapted to be mounted on accumulation reservoir and having horizontal partition walls.
