The invention relates to agricultural land reclamation, particularly drip irrigation garden wood, etc. plantations aimed at landing linearly.

A device for drip irrigation, comprising a housing with an inlet and outlet and located in it float regulating element, which, with the aim of improving the uniformity of irrigation, where the through hole, and a telescopic pipe, connecting the said inlet opening to the outlet opening of the housing (SU authorship 782766, M CL3A 01 G 25/02. Device for drip irrigation / C. F. Dmitriev (USSR), - 2765876/30-15; Claimed 15.05.1979; Publ. 30.11.1980, bull. 44 // Open. Of the invention. - 1980. - 44).

Despite the fact that the device is provided with an additional float regulating element, falling from the outlet, sized water droplets spread on the surface irrigated field. Only when large irrigation norms and high performance devices (up to 8 l/h) irrigation water promutual the top layer of soil to a depth of 0.2-0.3 m With drip irrigation, the root system of fruit trees and grapes is formed in the upper layer. To the South of the Russian Federation with the harsh continental climate and snowless winters root systems of trees partially or completely die (intervals of 3-4 years).

The closest object to the claimed device is an injector for drip irrigation, including outlet and a porous body, in which, to improve the reliability of irrigation and simplify the design, it is equipped with a pressure regulator, made in the form of a replaceable porous element is n, N. P. Mityanin (USSR). - 27 73423/30-15; Claimed 31.05.1979; Publ. 15.03.1981, bull. 10 // Open. Of the invention. - 1981. - 10).

This injector adopted us as the nearest equivalent.

Despite the fact that the porous body can be sunk into the soil to a depth of 0.6-0.7 m, the distribution of the moisture from it is in radial directions, and most of the water goes in the upper soil layer. Sucking the roots of fruit trees, and behind them and skeletal roots are addicted and oriented in areas with sufficient soil moisture. Described injector does not contribute to the formation of the core and fibrous root systems of fruit trees with the desired linear (strip) orientation. When the required care, both in the vineyards and nurseries, and industrial plantations, oriented in the lateral direction skeletal and sucking the roots of fruit trees are mechanically damaged working bodies of disk harrows, lemenih of stubble, cultivators, Shelestov and wicomoco-custom machines or staples.

The essence of the claimed invention consists in the following Task, which directed the claimed invention, " creating a sustainable fruit plantations by longline formation of root systems.

Trudovye plantations with irrigation in irrigated agriculture.

This technical result is achieved by the fact that in the known injector, comprising an outlet, a porous body with a pointed end and a pressure regulator in the form of a replaceable porous element according to the invention, it is provided with a mating with the inner surface of the porous body by the screen in the form of a hollow cylinder with decreasing speed in the direction of the pointed end of the housing angle coverage.

Due to the fact that the screen differentiation distributes irrigation water to the rooting depth of the horizon and in the desired direction, the root system of seedlings and saplings of tree plantations is formed predominantly rod type, with oriented skeletal and sucking down roots.

The invention is illustrated by drawings.

In Fig.1 shows a diametrical section of the injector for drip irrigation.

In Fig. 2-7 shows a horizontal cross section of the porous body, screen and pressure regulator in the direction of the pointed end of the housing.

Information confirming the possibility of implementing the claimed invention are as follows.

Injector for drip irrigation includes water outlet 1, the porous body 2 with the pointed end 3 and the pressure regulator 4 is th on the surface of the outlet 1 has an annular groove 6. The clutch 5 and the housing 2 in the upper part are provided with an annular sectional protrusions that when pairing with grooves 6 sink into them and hold the clutch 5 and the outlet 1 on the housing 2. Outlet 1 has an axial channel 7. Outlet 1 is connected with the nipple 8. On the surface of the nipple 8 by means of quick-release couplings 9 fixed pressure regulator 4.

The lower end of the pressure regulator 4 is closed by the stopper 10. The pointed end 3 of the housing 2 is also for him by the door. The injector is equipped with a screen 11. The screen 11 is made in the form of a hollow cylinder with decreasing speed in the direction of the pointed end 3 angle coverage1max to6min. Angle of coveragethe screen 11 of the inner surface of the porous body 2 in each stage is reduced by 30-45o. Screen 11 covers most of the outer cylinder nipple 8 and connected with the inner surface of the porous body 2.

Injector for drip irrigation when grown as seedlings and saplings of fruit trees is as follows.

Before watering injector pointed end 3 is injected into the soil to a depth of 0.6-0.7 m Above the soil surface EfE is the axis of symmetry of tree plantations. Water through the axial channel 7 water outlet 1 enters the porous element of the pressure regulator 4, passes through its pores and fills the cavity of the housing 2. The screen 11 is positioned so that the smaller part of irrigation water received in the direction of the row of trees. As the angle of coverage1the screen 11 of the inner surface of the housing 2 is the largest, then, accordingly, a smaller part of the water enters the surface layer of the soil. With increasing depth (the length of the housing 2 from the outlet 1) the scope of the angles2,3,4and5reduced, and the open porous surface of the housing 2 is increased. Through the pores of the housing 2 water injector goes into the surrounding soil. When passing through the pores of the pressure regulator 4 is cleared of water, and this provides the possibility of increasing the service life of the housing 2 of the injector without removing it from the soil. When the filling of the case 2 water creates a pressure, which prevents the release of water through the pores of the pressure regulator 4. The change of pressure in the network causes the same change of pressure in the area between the housing 2, the screen 11 and reg is negligible. This regulation of the flow rate allows the use of the injector in the gardens with difficult terrain with drops up to 1.5 meters

No float valve and the presence of the screen 11 can significantly reduce the diameter of the housing 2 of the injector. This reduces the cost of material and cost of the injector. The porous element of the pressure regulator 4 periodically, as clogging of its pores, remove from the housing 2 and washed with excess pressure purified from suspensions of water.

The proposed design of the injector allows you to create the structure of the underground organs of tree plantations with their features. Changing the position of the screen 11 in the housing 2, the sucking and skeletal roots without interference form and oriented in the right direction.

More moisture in the lower horizons orients the roots of seedlings in a vertical direction. This is achieved by a sustainable community tree plantations. The proposed injector for drip irrigation in comparison with the known droppers more economical consumption of water, has a simple structure, provides a regulated soil horizons water flow and increases the operational reliability of irrigation.

Formyl end and a pressure regulator in the form of a replaceable porous element, characterized in that it is equipped mating with the inner surface of the porous body by the screen in the form of a hollow cylinder with decreasing speed in the direction of the pointed end of the housing angle coverage.
