Description

The article solves the problem of obtaining scientifically based practical and experimental results of increasing the yield and oil content of sunflower seeds, based on the use of information EMF of EHF range for pre-sowing treatment of seeds.

The study of the biophysical effects of the electromagnetic field on sunflower seeds was carried out in order to determine the biotropic parameters of the electromagnetic field, which have a stimulating effect on the seeds. For this, a mathematical model of a sunflower seed in the form of a spheroid was developed.

For the calculations, the following frequency range of the exciting wave 25–40 GHz was chosen. The choice of this range is due to two circumstances. First, the relative dielectric constant of sunflower seeds in this range practically does not have frequency dispersion. Secondly, the wavelength is commensurate with the characteristic geometrical sizes of the seeds and, therefore, the intensity of the excited electric field inside the seeds resonantly depends on the frequency.

The measurement of chemiluminescence was chosen as the response of the biological object. For registration of extremely weak light fluxes of seeds, the photon counting method was chosen, which made it possible to carry out effective measurements of both spontaneous biochemiluminescence and induced information EMF. As a result of theoretical and experimental studies, a system was developed for measuring the chemiluminescence of seeds.

The purpose of the experiment was clarification of the optimal biotropic parameters of the information EMF, which would provide an increase in yield and quality of sunflower seeds when they are irradiated with EMF. The result of field tests showed the advantage of using electromagnetic technology over other methods of pre-sowing treatment of seeds
