Электроизгородь для защиты селекционных посевов от зайцев

Abstract

The threat of destruction of seedlings in breeding sowings of oil crops is the raids of hares, in a short time they can damage the leaves, stems and even the roots of plants and thereby cause irreparable harm to breeders. Existing methods to control hares: poisonous baits, fences, electric fence, upon contact with which animals receive a weak electric shock and jump away from it; are ineffective for scaring hares, since in some cases they can easily jump over the fence, in other cases hares can easily penetrate under the fence. In the department of mechanization of the V.S. Pustovoit All-Russian Research Institute of Oil Crops, an electric fence design has been created in which wooden poles with insulators are additionally equipped with wooden couplers installed to them at an angle of 350 at a level of 300 mm from the ground with two insulators each, on which current conductors are fixed, connected to each other and forming an external closed circuit of electrical protec-tion connected to the "-" output of the high-voltage pulse generator (HVI) and with a ground loop, and the main closed circuit of electrical protection is con-nected to the "+" output of the HVI and consists of five rows of current conductors, located respectively at a distance of 150 mm, 300 mm, 480 mm, 680 mm and 880 mm from the soil surface, and the rows of current conductors of the external circuit of electrical protection – at a distance of 500 mm and 800 mm from the soil surface, while the columns are embed-ded in the ground to a depth of 300 mm at a distance of 6000 mm from each other. The conducted tests of the electric fence in the field confirmed that it fully provides protection of the fenced territory of the breeding site from the penetration of hares into it.
