| Popis: | This article presents an installation for producing ozone. Ozonators have found widespread use in agricultural production. The most efficient means of ozone production today are ozonators using electric discharge. They are simple in design and have high ozone yield in comparison with other methods. The ozonator is designed with the use of discrete elements, CMOS logic elements of medium integration, and operational amplifiers of medium accuracy. The design elements have galvanic connection to the 220/380 V network. The device consists of the following main functional elements: a master oscillator, a signal conditioning device, a display device, an amplifier, a high-voltage output stage and power supplies. This ozonator is intended for use in agricultural production, in particular for the treatment of crops. Experimental trials of the laboratory ozonator were carried out concerning treatment of winter wheat seeds with ozone to improve their sowing qualities. Particularly, winter wheat seeds were subjected to ozone treatment with ozone concentrations of 2.5, 35.0 and 55.0 mg/m3. At these concentrations, the dependence of germination energy of winter wheat seeds on the exposure and settling time from the moment of treatment to seed germination was determined. As a result of research, energy of germination increased by 17.0 % in comparison with the control, germinating capacity in the best variant changed from 77.0 % to 95.0 %. |
