ОБОСНОВАНИЕ ПАРАМЕТРОВ ГРЕБНЯ ПРИ ВОЗДЕЛЫВАНИИ КАРТОФЕЛЯ

Abstract

It is necessary to form such a ridge in volume using the ridge technology of soil cultivation, which would allow the development of the necessary potato root system, and it would be possible to obtain the planned harvest with a sufficient amount of moisture and nutrients. The purpose of the study is to substantiate the parameters of the ridge. Mathematical methods were used in the study. It has been established that during the growing season of potatoes, a change in the given shape of the ridge occurs, since under the influence of precipitation, watering, soil self-settling, and shedding, the trapezoidal shape transforms into a round one. The need to create a fine-clump soil structure in the ridge, to create a groove on the top of the ridge and its use in ridge technology for potato production was justified. The ridge section parameters were adopted based on these data. Analytical dependencies were obtained to determine the cross-sectional area of the trapezoidal ridge, both newly formed and with an additional groove required for irrigation during the potato growing season. The required volumes of soil in the formed ridge were determined. Observations and calculations carried out for planting potatoes with a row spacing of 75 cm show that the shape of the ridge by the time of harvesting undergoes significant changes from the original. The volume of soil in the ridge at the beginning of its formation and before harvesting differs by 4.18%.
