Abstract

The article presents the results of theoretical and experimental testing of the machine made as a result of the research on the basis of the scheme and parameters of the cultivator, which processes the soil between rows and rows of vines with a low cost, including vine rows with soil hardness varying between 1.4-1.8 mPa, the circumference of the bushes and The required tractor power is 21.53-35.09 kW when the resistance changes in the range of 12.41-16.37kN when moving the range of working speeds in the range of 1.45-1.8 m/s. In the tillage system, it is important to loosen the rows between the vines without overturning them. Gray soil soils in Uzbekistan have different mechanical composition and are very poor in humus. Cultivation of the vineyard soil at a depth of 20-25 cm for many years leads to the formation of a plow heel, as a result of which the water-physical properties of the soil and the development of the root system deteriorate, which negatively affects the growth and yield of the plant. The leaves of the vines turn yellow, they drop their leaves early, the amount of fruits that can be obtained decreases, and accordingly the percentage of fruits that fall to the ground increases. A decrease in the water permeability of the soil prolongs the irrigation time, as a result of which water is used inefficiently. Deep softening improves the water permeability of the soil and, accordingly, increases the coefficient of effective plant use of moisture entering the soil.
