Results of research of pre-sowing disinfection of seeds in an electric field

Abstract

Annotation Purpose. Determine the effect of pre-sowing disinfection of seeds in an electric field on the indicators of sowing qualities and yielding properties. Methods. Analysis of the effect of the decontamination factors of the electric field on the pathogenic microflora of agricultural seeds and the creation of a model sample of electrotechnological means for its disinfection. Small-scale and laboratory experiments to determine the influence on the sowing qualities and yielding properties of seeds while simultaneously acting on the decontamination factors of an electric field. Results. Scheme of a model sample of an electrotechnological tool with simultaneous action on seeds of agricultural disinfectants of electrostatic field, corona discharge and ozone. Indicators of sowing qualities and yielding properties of “Terek” soybean seeds according to the results of small-field field experiment after pre-sowing decontamination in an electric field. Dependence of germination energy and laboratori likeness of wheat and maize seeds on the duration of simultaneous action of decontamination factors of electrostatic field, corona discharge and ozone. Conclusions. The simultaneous action of the decontamination factors of the electrostatic field, the corona discharge field and the ozone on soybean seeds improves its indicators of sowing qualities and yielding properties. In relation to control (seeds without disinfection in an electric field) the yield increase is 13.8–18.6%. The current tendency to reduce the duration of pest control is to increase the voltage of the electric field to 5.3 кV/сm. Disinfection of wheat and maize seeds in an electric field increases germination energy by 8–11% and laboratory germination by 5–9%. The highest value of germination energy was obtained with the duration of decontamination 30 min. Keywords: seeds, decontamination, electric field, simultaneous effect of decontamination factors, field experiment.
