A method for leaching irrigation at growing flooded rice includes primary flooding of irrigating map with layer of fresh water, keeping flooded layer for provision of enough duration and stability of washing process, two-three time change of it, water discharge from surface of rice fields before harvesting. Preliminarily, before beginning of watering period, one switches on inter-map draining with decreasing levels of earth waters to needed depth of desalting, flooding of watering map is carried out with forced flow rate, and after flooding, by means of inter-map draining, one periodically controls level of earth waters under rice field for effective washing and aeration of soils in all phases of rice development and in after-harvesting period. |
