PROSPECTS OF APPLYING ELECTROTECHNOLOGY IN GARDENING

The paper presents some application fi elds and examples of applying electrotechnology in agricultural production as exemplifi ed by the use of electric, magnetic and electromagnetic fi elds. The authors determined promising research areas concerning the application of electrotechnology in gardening: the use of magnetized water for watering tree crops and bushes; the use of a strong electric fi eld of high voltage to produce a fi ne electroaerosol in the form of fog or cloud of electrically charged solution droplets (chemical preparation to combat diseases and pests of garden crops) to increase the preparation effi ciency (from 25 to 75%) and reduce the environmental impact. The paper presents the designs of technical devices for obtaining magnetized water. The authors offer an original magnetic fi eld source consisting of an inductor with windings and a ferrite core and having additional features for regulating the rotation speed of the magnetic fi eld, and the formation of magnetic fi elds with different harmonic composition, depending on the shape of the output voltage of a transistor frequency converter. The paper also provides a description of an electric circuit (powered by a battery or a low-power rectifi er) of a small-sized source of a strong electric fi eld using high-frequency transformers, the mass and size of which are reduced twice at such frequencies.
