Basic Studies on Development of Electrical Weed Control System

전기방전식 잡초방제기 개발을 위한 기초연구

Motivated by the need fir developing the new method of weed control in place of chemical weedicide, this paper aims at making good use of electricity against environmental pollution. Compared with chemical weedicide, the electric method of weed control is functionally more versatile, effectively more rapid, and lower in terms of cost. In particular, this method will contribute to environmental protection. In detail the electrical weed control system which is the simple circuit for generating the electric current of high voltage is comprised of step-up transformer which rectifies the current and the capacitor which stores the energy. The effectiveness of electrical weed control system is evaluated by germination rate and control of Dgitaria Sangvinalis(Galinsoga ciliate). As a result, the electrical weed control system(high voltage spark discharge) can kill weeds effectively
