Abstract

The purpose. To justify an opportunity of application of periodic rice watering on existing rice irrigation systems of delta of Danube. Methods. Field, comparative analysis. Results. It is determined that mapchecks of wide front of waterflooding and dump of water have essential advantages before maps-checks of Krasnodar type at periodic rice watering using both sprinkling irrigation, and waterflooding. Waterflooding of such maps-check plots or secure of necessary watering rate of water is carried out on them twice more sweepingly. Due to that the necessary water regime on the whole area of map-check is created. Conclusions. Periodic watering at growing rice in Danube conditions of rice irrigation systems allows to diminish consumption of irrigating water in 4 — 4,5 times and to save on its pumping-over up to 2 — 2,5 thousand hrn/hectare.

Key words: rice irrigation system, fixed waterflooding, rice sprinkling irrigation, water- and power saving measures.
