The purpose of the research is to study the peculiarities of migration of radionuclides (cesium and strontium) and heavy metals (Cu, Cd, Zn, Pb) in the system "soil-plant-lysimetric waters" in the cultivation of miscanthus culture on solid fuel and to develop elements of miscanthus cultivation technology. for the production of environmentally friendly biofuels in contaminated areas. Research methods: stationary lysimetric experiment; laboratory; comparative and statistical. The essence of the work: development of highly efficient technology for growing miscanthus in contaminated areas for the production of environmentally friendly solid biofuels. To achieve this goal solved the following tasks: - to study the mobilization and immobilization processes of pollutants and radionuclides in the system "soil-plant-lysimetric waters" for growing miscanthus in contaminated areas; - to study the peculiarities of migration of heavy metals and radionuclides by soil profile depending on agronomic techniques; - to determine the coefficients of transition and accumulation of heavy metals and radionuclides during the cultivation of miscanthus. The optimal model of technology for growing miscanthus on solid fuel has been developed, taking into account the patterns of behavior of radionuclides and heavy metals in the system "soil-plant-lysimetric waters" in the contaminated area. This model allows to obtain the highest yield of miscanthus biomass - 31.7 t / ha, solid biofuel yield - 13.92 t / ha, reduce the specific radioactivity of biomass by 10-16%, reduce the content of heavy metals by 19-21%, reduce production costs by UAH 204.8 / t and increase the level of profitability by 23% compared to the option where the soil is contaminated with heavy metals and radionuclides.   Product Description popup.authors Potapenko Lyudmyla V popup.nrat_date 2021-01-05 Close
