Kornberger V. Resource-saving and sustainable water use regulation in rice production (Krasnoznamens'ka irrigated area as a case study)

Research object: process of forming of the mode of vodopolzovaniya on RIS, which was carried out in the single Landscape-meliorative system. Purpose of researches: development and introduction resource of saving, nature protection norms water serve and overflow-pipe on the rice irrigate systems due to perfection of technology of growing of rice, its intercommunications with the optimum biological and ecologic-ameliorative terms of growing of culture. Research methods: the field, laboratory, model, analytical, mathematical. Results of researches: 1) for a theory - the scientific-grounded mode of the use of water at growing of rice on livery soils in the conditions of the Krasnoznamenskoy irrigated system is first developed, in the basis of which optimization of the mode of irrigation of rice is fixed on opened RIS; technology of growing of rice taking into account the requirements of guard of natural environment is improved; acquired subsequent development of opening of mechanism of forming of high-quality and quantitative indexes of drainage-upcast flow from RIS; 2) for practice - the terms of growing of rice are improved, с/ga provided the rise of productivity of rice on the average on 8,21, economy of irrigation water, that allowed to decrease an irrigated norm from 24-25 to 15-18 tis.m3/ga, reduction of volume of drainage-upcast waters (DSV) from 8-10 to 2-3 tis.m3/ga and rise of their quality to normative-clean, that positively affected the ecological state of environment. Sphere of the use: economies of south region of Ukraine, sowing of rice.
