Characteristics of Сhanges in the Electrical Conductivity Properties of Weed Plant Tissues under Electropulse Damage

This work is devoted to one of the promising electrical technologies in agriculture: the electro-pulsed weeding of undesirable and weedy plants. This operation has high technological efficiency, is environmentally safe, and belongs to high-tech processes. Various electrical properties and parameters of the objects of influence, weeds, have been studied for practical application and technical implementation. The frequency dependence of the electrical resistance of plant tissue or the dispersion of this resistance over the frequency of the measuring current is used as the main studied characteristic. Experimental studies have allowed the authors to determine the nature of changes in resistance during plant tissue damage, which additionally makes it possible to evaluate such quantitative indicators as the energy absorbed by plant tissue and the ranges of variation of its resistance during the electro-impulse impact on it. Theoretical verification confirmed the qualitative convergence of the obtained results and their changes during damage with calculated values.
