The results of scientific research and practical experience of flax-growing farms have shown that the process of dew preparation of trusts occurs unevenly along the thickness of the stem layer. With prolonged bad weather, flax stalks sprout with grass and are nailed to the soil by rains. In this state, the lower stems in the layer rot and the quality of fibrous products is markedly reduced. Therefore, it is necessary to periodically wrap or fluff the tapes of the stems. Currently, on the country's farms, flax growers prefer fluffing flax-straw belts due to the high productivity and reliable operation of machines in the field. However, existing fluffers confuse the stems and increase their elongation. The authors note that the resulting large disorientation and excessive elongation of the stems in the layer are the main reasons for the low yield of long fiber in the flax mill. Taking into account the indicated problem, the scientists of Kostroma State Agricultural Academy proposed a fundamental-ly new process of fluffing rotted straw and developed a machine for its implementation. The ma-chine ensures the maximum preservation of the initial values of the structural parameters of the stem layer. The article describes the device and the principle of operation of the new two-line fluffer for flax-straw belts, describes the methodology for substantiating its operating modes and the re sults of experimental studies. At the same time, it was found that when the prototype of the fluffer is operating on flax-growing belts sprouted by grass and nailed by rain, it is necessary to set the pick-up drum in such a position in which its fingers will penetrate into the soil to a depth of at least 1.0 ... 2.0 cm. The possibility of increasing the forward speed of the unit movement to 3.1 m / s and more without a noticeable decrease in the quality of its operation was also revealed.

Introduction. When cultivating agricultural crops, it is necessary to take into account the plants’ need for moisture, nutrients, location by area of nutrition, determining illumination, etc. Taking into account the biological characteristics of crops, various methods of sowing are used to create favorable conditions for plant growth and development. An important condition for sowing is the uniform arrangement of seeds along the sulcus, especially in the cultivation of testes of small-seeded cultures. A key role in the uniformity of seeding is provided by the design parameters and kinematic operating conditions of the sowing device. Materials and Methods. To determine the optimal parameters and operating modes of the disk sowing device, methods of factor experiment and multi-criteria optimization were used. Results. Mathematical models of the technological process of sowing seeds were obtained based of experimental studies. Conclusions. To ensure the improvement of the seeding quality of small seeds, the design parameters of the experimental seeder: х4 – is the diameter of the cell; х5 – the number of cells on the disk, will tend to the maximum values. The optimum circumferential speed of the sowing disk should be in the range from 0.127 to 0.192 m/s, and the speed of the machine’s movement is no more than 2 m/s.

The paper presents data on the study of the effectiveness of new biological drugs-the biofungicides Trichozan and Vitariz and biological insecticide against the background of the action and aftereffect of the sideral precursors of long-legged flax. The research was conducted in the Scientific Research Center of the Ivanovo State Agricultural Academy in 2018-2020. The positive effect of the action and aftereffect of the sideral precursors on the productivity of plants and the yield of flax was established. The greatest increases in the yield of straw and seeds were obtained in 2019-2020 when flax was placed after the sideral precursors and the complex use of the biological products Trichozan, Vitariz, and Bioinsecticide. The quality of flax straw improved by 0.5-0,25 sortonomer with the interaction of the complex of biological products and the action of siderates and by 0.25 sortonomer-with the use of biological products for the treatment of seeds and plants against the background of the aftereffect of siderates. The level of profitability for the years increased by 41.9-11.7%, respectively.

Purpose. Improving the quality of the trichograms' resettlement by establishing rational operating modes of the dosing and sowing device of an unmanned aerial vehicle. Methods. Experimental studies using the method of planning a three-factor experiment, methods of statistical data processing. Results. Based on the analysis of the technical means for resettlement of the trichograms, the design of the dosing-sowing device of a unmanned aerial vehicle for the resettlement of the trichogram was substantiated. As a result of the experimental studies, it was established that during the deployment of a trichogram with a dosing-seeding device, a stable leakage of the material due to ejection was ensured by using diaphragms with a diameter of 2.5 mm or more. According to the results of the research it was established that with the increase in flight altitude, the quality of material distribution does not change significantly. But factors such as the height of the plants and the presence of obstacles on the field must be taken into account, so it is necessary to keep the flight altitude not less than 5 m. Due to changing the size of the confuser, the range of flight of the particle did not change, which leads to the conclusion to use a smaller cone of diameter due to which reduces the frontal resistance. When using a dosing-seeding device for resettlement of a trichogram on a quadracycle, due to air flow from propellers, the width of the capture significantly decreases. Therefore, for the qualitative distribution of biomaterials on the surface of the field, the distance between adjacent passages should be 6 m. Conclusions 1. The height of the flight of an unmanned aerial vehicle during the resettlement of the trichogram must not be less 5 m from the upper edge of the plant. 2. The uniform distribution of material on the surface of the field depends on the flight speed, which should be within the range of 3–5 m/s. 3. The quality of the material distribution increases from the right choice of the width of the ceiling, which should be about 6 m. Conclusions: dosing sowing device, ejector, unmanned aerial vehicle, biological protection of plants, reshaping of trichograms, norm of settlement, width of capture.

Harmful Effects

Theoretical calculations and experimental studies show that during the technological process of transporting seeds by technical means, in particular ladle conveyors, macro- and especially microtrauma of grains occurs, which affects a decrease in quality indicators. Analysis of the studies shows that the structural parameters of the working bodies, the biological and physico-mechanical properties of the kernels, as well as the material for the manufacture or coating of the working elements, affect the trauma and quality of the seeds. Experimental data showed that microtrauma of winter wheat grains before transportation was in the range of 22,9- 23,5%, and after completion of the transportation process was 45,3-46,4%, that is, doubled. Further studies to improve the quality of seeds of grain crops, reduce the harmful effects of microorganisms on caryopsis and reduce macro- and microtrauma should be carried out in the relationship and the complex of biological and physico-mechanical features of the entire technological process.

A significant influence on stability of the process of filling the CCM mold with liquid metal is exerted by the structural and technological schemes and designs of used devices, modes and parameters of filling the mold with the melt. All this is due to the features of the devices used and the improvement of their design. The high requirements for such devices have determined the need to create new devices designs to reduce the time spent on preparation for work and maintenance and to improve the quality of resulting metal billets. In scientific literature, including patents, more and more articles and materials are devoted to the development of new and improvement of the existing methods of supplying and stirring liquid metal in CCM and devices for their implementation. Experimental studies of liquid metal flow in CCM are a long, complex and laborious process. Therefore, mathematical modeling by numerical methods is increasingly used for this purpose. The authors have proposed a new technology for pouring liquid metal into a mold and a device for its implementation due to the use of effect of a deep-bottom submersible nozzle rotating in the mold with eccentric outlet holes. The purpose of this work is to simulate by proven numerical method a new process of filling a rectangular CCM mold with liquid steel and stirring it. Based on the developed numerical schemes and algorithms, a calculation program was compiled. The article describes an example of calculating the steel casting into a mold of rectangular cross-section and flow diagrams of liquid metal in it.

Over the decades, more attention has been paid to emissions from the means of transport and the use of different fuels and combustion fuels for the operation of internal combustion engines than on fuel consumption. This, in turn, enables research into products that are said to reduce fuel consumption. The report summarizes four studies of fuel-related innovation products. The studies covered by this report are conducted with diesel fuel and usually contain diesel fuel and three additives for it. Manufacturers of additives are based on already existing studies showing a 10-30% reduction in fuel consumption. Comparative experimental studies related to the use of commercially available diesel fuel with and without the use of additives have been performed in laboratory conditions. The studies were carried out on a stationary diesel engine СМД-17КН equipped with brake КИ1368В. Repeated results were recorded, but they did not confirm the significant positive effect of additives on specific fuel consumption. In some cases, the factors affecting errors in this type of research on the effectiveness of fuel additives for commercial purposes are considered. The reasons for the positive effects of such use of additives in certain engine operating modes are also clarified.

Water at the supercritical state is a new process for the chemical recycling. At this thermodynamic state i.e. Pc = 218 atmospheres and Tc = 374oC , water behaves very differently from its everyday temperament and it is a very good solvent for organic components. Experimental studies show that supercritical water can decompose hydrocarbons/polymers and produce useful products like 2-Azacyclotridecanone /lactam-1 from Nylon-12 (batch process). The decomposition process itself was carried out in batch reaction system in order to get more information about product distributions, time dependence, and scale-up possibilities.Keywords: supercritical water, decomposition, batch, polymer, hydrocarbon
