Abstract
Presents results of a study of the uniformity of distribution of irrigation water along the length of the drip lines at its pre-treatment in sand gravel and disc filters (typical) and hydrocyclone installation (experimental version) and the efficiency of water technology in the cultivation of corn. It was found that when using a sand-gravel and disc filter as a water treatment unit on a drip irrigation system, the coefficient of effective irrigation was 0.635, insufficient irrigation - 0.240, and excessive irrigation - 0.125. The use of hydrocyclone installation for water treatment, which combines the processes of capture of dispersed particles by the method of sedimentation in a centrifugal field and the filtration method provides an increase of the coefficient of effective irrigation to 0.715 and reduce the rates of under-and over-irrigation, respectively, to 0.20 and 0.085. Thus, increasing the uniformity of the distribution of irrigation water along the length of the drip lines ensures the regulation of irrigation of agricultural crops. In field experiments on corn cultivation with drip irrigation, an increase in grain yield was achieved by 9% when using an experimental version of the water treatment unit instead of the standard one on the irrigation system.
