The invention relates to agriculture and can be used in drip irrigation systems for crop cultivation with drip irrigation.
Known irrigation tubing drip irrigation system that contains installed in the cavity of the pipeline device for magnetised irrigation water in the form of micromagnets and droppers, each of which has a housing with inlet labyrinth channel, a flexible membrane cover and outlet hydraulically connected to the hole in the wall of the irrigation pipe, characterized in that the or case, or a flexible membrane, or cover, or along the housing, the flexible membrane and the cover is made of a ferromagnetic alloy magnetic field of 0.2 to 0.8 T (RU patent # 90966 U1. Irrigation system piping drip irrigation / Vmimages, Amilda. Publ. 27.01.2010. Bull. No. 3).
The disadvantage is installed in the cavity of the pipeline described above device for magnetization that irrigation water is a high probability of blockage (clogging) of the labyrinth channel enclosure drip from the magnetic material of iron particles or iron oxide.
Known outlet, mounted on the output hole of the pipeline and including a seal and setroubleshoot element, characterized in that the seal is installed on the outer surface of the pipeline, and setroubleshoot element freely disposed between the seal and the pipe in the zone of the outlet, and a seal is made in the form of a ring covering the pipeline (RU patent No. 2056734 C1. Outlet / Sppicav. Publ. 27.03.1996).
The disadvantages of the pipeline is installed on the surface in the zone of the outlet seal in the form of a ring is that the ring is not fixed to the pipeline from longitudinal displacement relative to the outlet and made permanent, which makes it impossible for the industrial production pipelines described floodgates.
Known irrigation pipe with integral droppers containing devices magnetised irrigation water, which is made in the form of the magnets of the ferromagnetic alloy in the form of rings embedded within the drip line and adjacent to each dropper in order the direction of the poles along the drip line S-N-S-N. Irrigation piping provides increased organisti vegetable crops due to intensive magnetised irrigation water (Patent No. 2323567 C2. Irrigation system piping drip irrigation / Vmimages, Amilda. Publ. 10.05.2008. Bull. No. 13).
To the disadvantage of the irrigation pipeline include: a large resistance to the flow of pumped irrigation water due to mnogokrat is Oh its turbulence embedded magnets in the form of rings, as well as technical difficulties in the manufacture of such pipelines.
There is a method of weed control in the protective zone of the rows of cultivated crops in drip irrigation systems. The method includes laying on the field irrigation pipes with droppers, combined with devices for magnetised irrigation water, and moving along the pipeline unit with tillage machine. The latter is made complete with product sections in the form of swivel on the vertical posts and break within a protective zone product rows of knives. The knives are magnetically sensitive sensors, kinematically connected through a multichannel amplifier with the mechanisms of rotation type of knives. Plants when planting planted in the center area of each irrigation drip. Magnetically sensitive sensors made in the form of overlapping cross-border laying irrigation pipes rods. Sensors placed on the product sections in the transverse vertical plane above the irrigation pipelines for the axes of rotation of the vertical posts before the point of closing the outer ends of the knives product (Patent No. 2329645 C2. Method of weed control in the protective zone of the rows of cultivated crops in drip irrigation systems / Vmimages, Amilda. Publ. 27.07.2008. Bull. No. 21).
The disadvantages described the FPIC of the BA control weeds in the protective zone of the rows of cultivated crops is low induction of the external magnetic field devices for magnetised irrigation water due to the adaptation of the walls of the drip line reduce the reliability of operation type of knives signals from the magnetically sensitive sensors.
The closest analogue to the claimed invention relates to the method of determining the designated planting in drip irrigation system, which consists in the fact that the surface irrigation pipes at the locations of culverts pre-applied barcode, that when hand planting plants recognize visually, and when mechanized read during movement of the planting unit posted barcode scanners. This method provides a saving of irrigation water and fertilizers due to the landing of each plant (manually or automatically by signals barcode scanner) directly in the center of the zone irrigation drippers (Patent No. 2368131 C1. The method of determining the designated planting in drip irrigation system / Vmimages, Amilda. Publ. 27.09.2009. Bull. No. 27).
The disadvantages used in the described method of pipeline barcode in the placement of culverts are its limited functionality, namely the absence in these pipelines combined with droppers magnetic elements for magnetised irrigation water and implementation of weed control in the protective zone of the rows of cultivated crops signals magnetically sensitive sensor the Cove, installed on the product sections tillage machines and responsive to the magnetic field combined with droppers magnetic elements.
The main problem solved by the claimed invention is the ability of complex technological operations in the cultivation of agricultural crops through the use of irrigation pipe with an external magnetic elements coated on their surface in the locations of the culverts bar codes.
The problem is solved by the invention due to the fact that on the surface is known irrigation pipe during its manufacture fix encircling the pipe from the outside with a closure ring flat elastic plate of magnetic material in the shape of a square or rectangle with beveled from opposite sides edges at an angle of not more than 30° and deposited on the surface of the plates parallel to the beveled edges of the barcode and holes in the middle, placed coaxially and water diversion.
From the experience of agricultural production, namely the implementation of the comprehensive implementation of several technological operations through the use of irrigation pipe with an external magnetic elements deposited on their surface in the locations of the culverts barcodes, not izvestno about the identity of the proposed solutions to the same problem. From the patent and technical literature is also not known about the integrated use of irrigation pipeline to perform several technological operations with inherent identical announced irrigation pipeline essential attributes.
