agriculture. SUBSTANCE: method involves supplying water to irrigation hose; distributing water via water discharge pipes to furrows; providing displacement of movable member along irrigation hose. During displacement of movable member in irrigation hose, portion of water is directed through annular gap between movable member and irrigation hose wall. The greater is water cloudiness, the larger part of irrigation hose section is closed by movable member to increase water flow rate in annular gap. Increasing of water flow rate is performed 3-5 times during irrigation period depending on water cloudiness. Such method allows pipelines to be prevented from silting and, as a result, amount of works connected with additional pipeline cleaning processes to be reduced. Silt removed during required pipeline cleaning processes may be used as valuable mineral fertilizer. EFFECT: reduced pipeline maintenance costs, increased service life of movable member and simplified method. 1 dwg
