FIELD: agriculture. ^ SUBSTANCE: device can be used for stimulation of development and growth of plants due to pulse magnetization. Plants are subject to complex influence of periodical sequence of preset number of magnetic induction with different frequencies at four different parts of plant at the same time. For the purpose the device is used which has continuity of service source. First output of the device is connected with first input of stabilized power unit. Power unit is also connected with first terminal of input of rectifier circuit through current limiter and first switch. Second output of continuity of service power source is connected with second terminals of inputs of stabilized power unit and rectifier's circuit. Minus terminals of outputs of power unit and rectifier's circuit are connected with second terminals of first voltage indicator and accumulating capacitor, the second and third switches through common bus. Common bus and positive terminal of stabilized power unit are connected to power circuit of logic elements and gates. First terminals of first voltage indicator and accumulating capacitor are connected with first terminal of first inductor coil. Second terminal of the coil is connected with first terminal of second switch. Control input of the switch is connected to output of first amplifier-former. Second amplifier-former is connected with control input of third switch. Control desk is connected with control input of digital timer. Output of timer is connected with input of NOT gate and with control input of first switch through galvanic decoupling member. Output of master oscillator is connected with count C-input of frequency divider which has m outputs connected with m inputs of commutator. Device also has first diode and first univibrator, four-digit binary counter, second, third, fourth, fifth, sixth, seventh and eighth diodes, second, third, fourth, fifth and sixth univibrators, second, third and fourth accumulating capacitors, voltage indicators and inductor's coils, third and fourth amplifiers-formers and switches, and sound signaling unit. Anodes of first, second, third and fourth diodes are connected with positive terminal of output of rectifier's circuit. Cathode of the first diode is connected with first terminal of first accumulating capacitor. Cathodes of second, third and fourth diodes are connected with first terminals of second, third and fourth accumulating capacitors, voltage indicators and inductor's coils correspondingly. Second terminal of second coil of inductor is connected with first terminal of first switch. Second terminals of third and fourth inductor's coils are connected with common bus through fourth and fifth switches. Input of digital timer is connected to output of master oscillator. Output of commutator is connected with count C-input of four-digit binary counter. First and second outputs of counter are connected with inputs of first and second amplifiers-formers through first and second univibrators. Third and fourth outputs of four-digit binary counter are connected with control inputs of fourth and fourth switches through third and fourth univibrators connected in series. Output of NOT gate is connected with R-inputs of frequency divider and four-digit binary counter; input of fifth univibrator and with input of sound signaling unit though six univibrator. Output of fifth univibrator is connected with anodes of fifth, sixth, seventh, eighth diodes. Cathodes of the diodes are connected with inputs of first, second, third and fourth amplifiers-formers. Inductor is made in form of hollow frame onto surface of which the four isolated multi-turn sectional coils are disposed for change in distance among them and re-mounting to provide fixation relatively each other. Device provides complex influence onto plants with periodical sequence of preset number of magnetic inductance pulses with four different frequencies simultaneously at four different parts of plant for stimulating exchange processes in them and to help them adapting to environment. ^ EFFECT: higher efficiency of stimulation. ^ 2 cl, 3 dwg |
