The results of laboratory field studies of the disinfectant for layer-by-layer seed treatment

Annotation Purpose. Improving the efficiency of pesticide use by developing a technical tool for environmentally friendly layer-by-layer treatment of seeds with protective and stimulating preparations, which will improve the quality of seed treatment and environmental safety Methods. The study used the method of planning experiments and experimental calculation method. Results. Laboratory field studies of an experimental sample of a disinfectant for layer-by-layer treatment of seeds with protective and stimulating preparations were carried out in production conditions. An experimental dependence of the quality indicators of layer-by-layer treatment of crop seeds with protective and stimulating preparations on the modes of operation of the disinfectant was obtained. Conclusions. Experimental dependences of the productivity of the disinfectant on the height of the outlet slit of the seed dispenser were obtained. It is established that the productivity of the seed treatment process is from 0.6 t/h to 7.2 t/h. Mathematical models of the relationship between the quality of layer-by-layer seed treatment and the supply of seeds and working fluid. According to the production test of the experimental sample of the disinfectant for layered treatment of seeds with protective and stimulating preparations, it was found that when feeding sunflower seeds 0.32 kg/s and applying the working solution of the disinfectant 16 ml/s, the completeness of seed treatment was 82%, unevenness – 8%, seed injury – 0, the productivity of the seed treatment process – 1.15 t/h. The specific energy consumption of the process was 0.82 kW×h/t of treated sunflower seeds. Keywords: seeds, disinfectant, layer-by-layer treatment, protective and stimulating preparations, parameters.
