The effect of a pulsed low-frequency magnetic field on the seed germination and the growth of seedlings of strawberry garden under different conditions of processing and functioning of the apparatus magnetic-pulse processing of plants (MPP) developed by us has been established experimentally. The research has shown that the value of the germination energy of seeds treated with a pulsed magnetic field varied from 29 to 47 percent, of germination from 34 to 48 percent. The highest value of their germination corresponds to an irradiation frequency of 16 Hz and an exposure time of 360 seconds with an induction value in the treatment zone of 5 mT. The maximum increment in the germination of irradiated seeds was 14 percent compared to the control sample. The positive effect of pulsed electromagnetic fields on linear dimensions of germs has been revealed. The increase in the biometric parameters of strawberry shoots affected their weight, compared to the control it increased by 33.3 percent.

Numerous studies of various physical factors show the promise of using pulsed magnetic fields in bioregulatory technologies to stimulate plant life and growth processes. As a result of exposure to garden strawberries with a low-frequency magnetic field, the quality of planting material improves, plant immunity increases, crop growth and development accelerates, the number and weight of berries increase. The article presents a developed automated device for magnetic pulse processing (MPP) of plants, considers the device, design and principle of its operation. The electrical circuit of the device and its technical characteristics are given. According to the results of a laboratory experiment, the magnetic field parameters of the working body of the device in the near zone of a flat spiral coil were established. The numerical value of the magnetic induction at a distance of 100 mm from the center of the coil is 8.3 mT.

The Relationship

The article presents the results of experimental studies on the magnetic pulse treatment of strawberries in a climatic chamber. The analysis of the obtained data showed that the greatest effect from the treatment of plants with a low-frequency magnetic pulse field in the phase of peduncle formation was obtained on plants that were treated with a magnetic induction equal to 4 MT, a pulse repetition frequency of 32 Hz and a duty cycle of 20. The relationship between the parameters of low-frequency magnetic pulse radiation and the photosynthetic activity of the leaf apparatus at various stages of ontogenesis, and the qualitative composition of fruits at the stage of maturation is revealed. The high sensitivity of plant organisms to the effects of energy factors, the parameters of which differ in exposure and physical factors, is shown. At the same time, the nature of the response of plants is complex, ambiguous and is determined not only by the electrophysical parameters of the electric field, but also by the specific, varietal and technological features of the crop.

Introduction. The current level of agricultural production, including horticulture, is determined by intelligent machine technologies and new generation technical means with modern information and instrument support. The implementation of digital intelligent agricultural technologies in industrial gardening requires a fundamental change in the paradigm of technical support, based on the development and application of new automatic and unmanned machines, equipment and software for managing work processes of machines, navigating technical means, controlling the implementation of technological operations, monitoring the yield of agricultural crops, analyzing diseases and pests on plants and other technological functions. Materials and Methods. 3D model is visualized in the computer-aided design “KOMPAS-3D” through using the methods of mathematical modeling, theoretical mechanics and optimal design. A prototype of an automated unit for magnetic pulse processing of plants is made. The program code for calculating the required movement of the actuator rod is developed in the Sublime Text editor. C++programming language was used. The functionality of the computer program is related to the capabilities of controllers STM32, Arduino Mega/ Uno/Nano. Nextion 2.4 (the TFT screen 320x240) for the graphical output and interaction was used. Results. An automated unit with the algorithm of the drive control system of working bodies were developed during the technological operation of magnetic pulse processing of plants, taking into account the agro-technological parameters of garden plantations. A computer program with both automat and remote control was designed for driving the working bodies. Conclusions. The unit allows introducing a new environmentally safe technological method of stimulating vital and growth processes of fruit crops. This device provides the most efficient operation through automatic adjustment to various agro-technological parameters of plantings, providing the required value of magnetic induction in the working area on plant objects in the field.
