Calculation of Humidification Contours upon Drip Irrigation of an Intensive Apple Orchard in Zhambyl Region

Abstract

Based on the increasing efficiency and productivity of water resources by improving the technique and technology of intensive drip irrigation of apple orchards, calculations were presented on the formation of a moisture contour by drip irrigation for apple seedlings and seedlings of low-growing fruit-bearing apple orchards in the conditions of the foothill zone of the Zhambyl region, the justification of the intensity and time of water supply, the placement of the number of droppers providing moisture to the root layer of apple trees grown to maintain humidity in accordance with 0.8 MC in the foothill zone of the Zhambyl region on light grey soils with insufficient natural humidity. As the apple trees grow and develop, the need to moisten the root layer along the drop line increases until the wet contour is completely covered. It is established that during mass watering of apple orchards, the regularities of the process and dynamics of soil moistening are established depending on the value of the irrigation rate. With drip irrigation, the root layer of the soil is compacted.
