Dudchenko K. Regulated using drained-discharge water of rice irrigation systems

Object of researches - process of forming of the mode of the use of water on rice irrigation systems for the managed use of drainage-upcast waters. The purpose of researches is development of scientific bases of the managed use of drainage-upcast waters of the rice irrigation systems with providing of saving of resources and nature. Methods of researches - the field; laboratory; statistical; method of mathematical design; computation-comparative. Results of researches - For a theory: It is developed first, it is grounded scientifically, it is patented and the method of the managed use of the drainage-upcast rice irrigation systems and device is applied in industry for adjusting of level of drainage-upcast waters of the rice irrigation systems. For practice: the developed method of the managed use of drainage-upcast waters of the rice irrigation systems allows to decrease an irrigation norm on the average on 1220 m3/ga, volumes of overflow-pipe outside the system on 1200 m3/ga, negative influence of rice-grower on adjoining territories diminishes as a result, efficiency of the use of irrigation water and productivity of rice rises. The sphere of the use is the agricultural enterprises of south of Ukraine.
