Due to the orientation of the world's leading countries on environmentally friendly agricultural production technologies, more and more attention is being paid to the development of electro-technological processing methods. The main advantage of electromagnetic technology for pre-sowing seed treatment with low-energy radiation of the EHF range is the possibility of improving their growth and development by mobilizing the internal reserves of the seed itself, accelerating the diffusion of molecules through the cell membrane, the speed of chemical reactions and causing redness plants and promotes yield without chemical or biological agents or genetic engineering methods. The technology of seed treatment EMF EHF allows to store in the seed all the nutrients, vitamins and minerals, which when processed by other methods is difficult to achieve. The study is based on the analysis of literature, theoretical and experimental studies of the energy and spectral characteristics of the diode generator in the EHF wavelength range, which can be concluded that the increase in plant yields is possible based on the use of millimeter-wave electromagnetic radiation for pre-sowing seed treatment. The article proposes a technique for investigating the energy characteristics of a semiconductor six-diode generator on avalanche-spanning diodes for pre-sowing seed treatment of cultivated plants. The result of the developed technique is that one of the main elements of the plant for pre-sowing seed treatment is the emitter of EM energy, which should form the necessary radiation pattern and provide a sufficient level of power flow density on the grain.","PeriodicalId":166753,"journal":{"name":"Podilian Bulletin: Agriculture, Engineering, Economics","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126651809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the promising directions is to study the conditions of giant miscanthus productivity increasing on the basis of determining the features of plant growth and development, improving the elements of cultivation technology in the conditions of the Western Forest Steppe. As a result of the observations and calculations, the peculiarities of plant growth and development in the first and subsequent years of vegetation and the formation of the above ground mass (biomass) of giant miscanthus were analyzed, depending on the soil and climatic conditions of cultivation. The regularities of growth conditions dependens, development and formation of miscanthus productivity due to influence of agrotechnical factors of planting density and mass of rhizomes are established in the study. Biometric indices of giant miscanthus plants in sprout height for October make a maximum value of 159 cm for planting density of 15 thousand plants / ha with mass of rhizomes 41-70 g. The maximum value of the biomass yield indicator was noted for planting density study of 15,000 units / ha with rhizomes of 41-70 g, which averaged 18.5 tons / ha during the years of analysis. Based on the results of the research, for providing a high productivity of miscanthus giant plants as raw material for Western Forest-Steppe biofuel production, the planting density of 15 thousand plants / ha with rhizomes 41-70 g is recommended.

In turn, this leads to an increase in the dynamic loading of nodes and components of machine-tractor aggregates, an increase in the level of oscillation and the emergence of dynamic and vibrational loads, which negatively affects both the node and components of the tractor or the aggregate, and the implementation of agrotechnical requirements. An analysis of recent studies and publications has shown that the introduction of energy-intensive technology into agricultural production leads to a decrease in soil fertility due to spraying and re-compression by engines, which aggravate agro-ecological indicators. In the study, the analysis of sources of vibrations and oscillations of elements of machine-tractor aggregates is presented. The frequency of influence on machine-tractor aggregates of various agrofones at different speeds of motion is analyzed. Experimental studies have determined the spectral density of the hook effort of the tractor during cultivating on disk field and steam. The results of experimental studies of the active damping system are presented. The result of the study is the suggestion to reduce the oscillations of the tractor and agricultural machine to justify comprehensive measures that prevent deterioration of the conditions of the unit. Fluctuations of the tractor, caused by sources of excitations, lead to deterioration of the performance of agrotechnical requirements due to the non-straightforwardness of the trajectory of motion, redevelopment of soil.

One of the effective methods in reducing the accumulation of radionuclides in crop production, in particular fodder, is the application of trace elements that are lacking in the Polissya area of Zhytomyr region. In addition, the trace elements contribute to increasing the yield of plants and improve their nutrition. As a result of the research in the Naroditsky district of Zhytomyr region, Polissya STOV, we found that the application of trace elements in the form of salts of trace elements Co, Cu, Zn, Mn contributed to the increase in the yield of green mass of white lupine and lupine of yellow on 2,4 and 3,6%, or on 10 and 10.7 g, of complexones of these trace elements, respectively, on 11,2 and 13,5%, or on 31,0 and 58,0 ts. Salts of trace elements contributed to a decrease in the specific activity of the green mass of lupine white by 18%, or 1.2 times, yellow lupine - by 11%, 1.2 times. Plasma complexes contributed to a decrease in the specific activity of green mass of white lupine and lupine of yellow on 24%, or in 1,3 times. Specific activity of the green mass of white lupine was high and exceeded the activity of the green mass of lupine yellow in 6.3 times, although the cultivation of cultures was carried out on the same fields, however, at different periods. White lupine was sown in the early spring, during which a considerable amount of precipitation fell during the vegetation period. Therefore, in our opinion, a significant increase in the specific activity of the green mass of white lupine was conditioned by the weather conditions. The maximum specific activity of the green mass of white lupine was 2003 Bq / kg, the minimum is 1526 Bq / kg, which is lower by 477 Bq. Reducing the specific activity of lupine is due to radio-blocking effect of micronutrient complexonates. Salts of trace elements contributed to a 1.2-fold decrease in the specific activity of the green mass of the culture.","PeriodicalId":166753,"journal":{"name":"Podilian Bulletin: Agriculture, Engineering, Economics","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116186788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
