Abstract

The article deals with the influence of structural and technological parameters of sprinklers and terrain on the uniformity of irrigation water distribution in the field.

They are given characteristics of developed and introduced in manufacture in the  Saratov State Vavilov Agrarian University with LLC “Meliorative machines” of the modern domestic wide-cut sprinklers “Kuban-LK1M” (Cascade) and  “CASCADE”, as well as the results of experimental studies of operation of machines for irrigation areas with difficult terrain. The data of pressure changes along the water pipeline depending on the terrain slopes are presented. The distribution of the rain layer under the machine spans for the modes of motion of 20  and 40% is obtained. The influence of the terrain and speed of movement of the machine on the efficiency ratio of irrigation is given. The results of tests of sprinklers with frequent placement of sprinklers and pressure regulators are presented. Ways to increase the uniformity of irrigation by sprinkler machines on slope lands are outlined.
