В статті представлено результати експериментальних досліджень по встановленню впливу ступеня розрідження у вакуумній камері на появу пропусків та двійників при висіві насіння пневмомеханічним висівним апаратом, оснащеним комірками з направленим вектором дії. The aim is research of influence of the degree of liquefaction in a vacuum chamber to the emergence of omissions and doubles when dosing device with pneumomechanical seed doser directed action. Found that in the range of operating speeds (V = 0,2...0,6 m/s) reduces the likelihood of increase in liquefaction omissions several times. This indicates that apart forms seeds an important role in suction and transportation plays density material (seed weight) which affects the distribution effort in delighted her cell. Increased liquefaction contributes to the formation doubles, the number of which depends also on the shape of and density of seeds fit them to the cell. When increasing liquefaction increases probability of occurrence of doubles. At that, this dependencies is typical to all cultures. Dependencies are nonlinear character with the gradual increase of the likelihood doubles at rising liquefaction.
