ПОЛЕВЫЕ ИССЛЕДОВАНИЯ СОШНИКА ЗЕРНОВОЙ СЕЯЛКИ С ШАРНИРНЫМ СОЕДИНЕНИЕМ НАПРАВИТЕЛЯ СЕМЯН И РЫХЛИТЕЛЯ ПОЧВЫ С КОРПУСОМ

Abstract

The uniformity of seed distribution along the length and depth of the row (sowing spacing) depends on the correct operation of the opener of the grain seeder, but not all modern openers have these indicators, so the scientists of the Penza State Agrarian University developed a grain seeder opener with a hinged connection of the seed guide and soil cultivator with the opener body, using which solves this problem. The distribution of seeds of spring barley variety "Sursky Favorit" by the depth of placement when using the developed coulter, compared with the indicators obtained using a standard double-disk coulter, was studied in the course of laboratory and field tests. According to the obtained graphic dependence, which characterizes the distribution of seeds according to the depth of placement depending on the type of coulters, it was found that the number of seeds in a given layer is 4-6 cm when sowing with a coulter of a grain seeder with a hinged connection of the seed guide and soil ripper with the coulter body and a standard double-disk seeder coulter SZ-5.4 is 91% and 71%, respectively. A decrease in the uneven distribution of seeds along the depth of the furrow will occur when using an experimental coulter, which in turn will affect the increase in yield. Yields will increase by 12% on average compared to the standard coulter.
