The role of the etching process in the technology of cultivation of grain crops in the Tyumen region
The process of dressing seed material with growth regulators, microfertilizers, insecticides and anti-stress drugs on an industrial scale is more often carried out in continuous chamber dressers. At the same time, mechanical damage to seeds occurs, which reduces their germination, yield and grain quality. The choice of a constructive-technological scheme and modes of operation of the treaters affects the quality of etching. The principle of operation of modern treaters includes mechanical transportation and supply of seeds to the treatment chamber, where the preparation is sprayed and mixed with the working fluid and seeds, and the treated seeds are unloaded using mechanical devices. The disadvantages of dressing machines include increased consumption of the drug (working fluid), damage to seeds by the work of mechanical organs, as well as uneven application of the drug throughout the mass of seeds. The paper analyzes modern devices for dressing seeds in order to improve the dressing process and minimize mechanical damage to the seed material.
