abstract 1541910028 issue 154 pp. 289 – 299 30.12.2019 ru 246
The work is devoted to studying the nature of the effect of various doses of the drug called "Regalis" on the formation of the vegetative and generative organs of apple plants. Years of research - 2016-2019 Field experiments were carried out in JSC company "Agrocomplex" named after N.I. Tkachev in the Vyselkovsky district. Plantations were laid in 2007. Planting pattern 4.0 × 1.0m., garden irrigated, with support. The soil of the site is ordinary carbonated black soil (chernozem), the thickness of the humus layer is up to 120-140 cm. As a result of field and laboratory studies of the condition of 9-12 year old Gala apple trees grafted on P-59 rootstock, it was established that the annual treatment of apple trees for different phenophases with a preparation Regalis at a dose of 1.25 kg / ha has a significant effect on both the size and the number of vegetative and generative formations. It was determined that triple treatment of apple trees with regalis in 43.11% reduces the number of shoots longer than 60 cm, and double - by 31.39%. Structural changes in the distribution of vegetative and fruitful formations per 1 meter were noted in axial branches of the first order. Under the influence of the drug, the number of full-fledged “closed” buds in 2017 increased by 88.8%, and in 2018 by 70.9% compared with the control. The use of triple treatment with Regalis significantly reduces growth activity and has a positive effect on the passage of organogenesis of apple flower buds

PROSPECTS FOR THE DEVELOPMENT OF URBAN STREET ROAD INFRASTRUCTURE

abstract 1541910029 issue 154 pp. 300 – 316 30.12.2019 ru 280
The development of a city can go in two ways -extensive and intensive. Intensive involves a qualitative rethinking of the necessary work, optimization and improvement on the basis of existing infrastructure. An extensive method of development is an increase in physical volumes, for example, an increase in territories. At the moment, the transport system of the city of Krasnodar is extremely busy. The city occupies one of the first places in the number of vehicles, roads with such a traffic load can not cope, resulting in numerous congestion on the roads. In addition, an average of 150 thousand cars enter the city every day, and this creates an additional burden on the transport system. In the morning there is a large influx of cars from the main entrances to the city. And in the evening there is no less strong loading points of entry into the city, as those who arrived in the morning leave the city. Information technology is designed to save our time and effort. At the same time, one of the problems that "eats" time is traffic jams. You can get from one place to another at one time, but subject to traffic jams, this time can increase several times. Why not use technical and software tools to solve this problem!? Now almost everyone has a smartphone, with a Navigator loaded into it. There are many variations of these navigators with approximately the same functionality. But what if the Navigator in your smartphone not only chose the shortest path for you, but also helped in unloading traffic throughout the city, reducing traffic congestion to a minimum

MINIMIZATION OF RESOURCE COSTS IN THE DISTRIBUTION OF PRODUCTION TASKS OF A COMPANY TAKING INTO ACCOUNT ITS STRUCTURE

abstract 1541910030 issue 154 pp. 317 – 326 30.12.2019 ru 313
The problem of the optimal distribution of production tasks is one of the important problems of effective planning of processes associated with production at the enterprise. However, the classical approach to solving this problem becomes of little use when the individual stages of the production process are performed sequentially and in the case when it is necessary to take into account the structural features of the technological processes of the enterprise. Purpose of work: to develop a methodology for minimizing costs in the distribution of production tasks, taking into account the structural features of the technological processes of the enterprise. We built a multicriteria discrete optimization model for the distribution of production tasks according to the structure of production elements. One of the methods based on the proposed model is proposed, which allows to identify groups consisting of four elements in the production structure of the enterprise. The model is built using a network design which are pre-fractal graphs. The use of pre-fractal graphs allows you to naturally represent the structure of production and technological links of the elements of the production system of large enterprises. The results of the work is the developed effective methodology for solving the problem of the network distribution of production tasks, taking into account the structural features of technological processes at the enterprise, the economic effect of which is to minimize resource costs. Based on the constructed model, we can develop automated means of monitoring and managing the production processes of a company

BIOTECHNOLOGY OF IMPROVEMENT AND PRESERVATION OF NATIVE DON GRAPE VARIETIES

abstract 1541910031 issue 154 pp. 327 – 347 30.12.2019 ru 227
The article presents the results of microclonal reproduction and recovery of native grape varieties, the creation of basic nursery. In addition to the culture of apical meristems, we have developed a chemotherapy using salicylic acid. A method of decontamination of plants from mycoplasma infection has also been developed, which includes the introduction of the antibiotic Cefotaxim in the nutrient environment at a concentration of 50 to 450 mg/L, depending on the degree of infection of plants. Adding to the nutrient medium of the drug Emistim reduces the death of meristems from infection by 3-5 times, improves their differentiation. The use of the drug Melafen helps to improve morphogenesis and quality characteristics of plants. The high survival rate of meristems during adaptation to non-sterile conditions has been noted. Biological testing on herbaceous indicators showed no chronic diseases. Plants after adapting to non-sterile conditions are planted, in the form of vegetative seedlings with a closed rootsystem, on the basic nursery. The survival rate of plants was 70-80%, in some varieties it is higher: 96.4% (Sypun black) - 98.6% (Krestovsky). It has been proved that in vitro clonal microbreeding there is no change at the genetic level even after 8 years of cultivation, which confirms the reliability of the developed technology of reproduction and recovery of native grape varieties in vitro

abstract 1541910033 issue 154 pp. 360 – 382 30.12.2019 ru 262
Improvement of domestic breeds of Merino sheep remains an important task. The reorientation of the industry to wool-meat and meat-wool direction of productivity can contribute to the restoration of domestic sheep breeding. An example of such conversion is a relatively young breed called Dzhalginsky Merino, created in the Stavropol region on the basis of the Stavropol breed with the involvement of resources of domestic and world breeding. In the current situation, it seems relevant to use Dzhalginsky Merino, in order to improve the meat and wool qualities of sheep of domestic fine-wool breeds. Obtaining a new genetic combination of animals, formed by combining the genotypes of breeds Salsky, Stavropol and Dzhalginsky Merino will increase the efficiency of the industry in a market economy and will provide a more complete use of the productive potential of the breed. The results of studies on obtaining and use of animals, new genetic combinations of a wool – meat direction of productivity, with high energy of growth, meat and wool productivity, improves the efficiency of Merino sheep are an important theoretical justification for making a contribution to zootechnical science, with the aim of improving fine-wool breeds of sheep and can be used in practical work in the production of high quality lamb

APPLE ROSETTE DISEASE IN NORTH CAUCASUS PLANTATIONS

abstract 1552001001 issue 155 pp. 1 – 12 31.01.2020 ru 223
The article presents the results of a study of the apple tree rosette disease found in a collection garden and having a viral nature. The rosetting has typical signs of manifestation. Sick plants develop narrow small chlorotic leaves. Rosettes of leaves on the upper cervical and lateral shoots are formed as a result of the convergence of internodes. The spread of the rosetting in the planting reaches 10-11 %. The prevalence of viral disease varies among the 44 varieties of apple trees of different ecological and geographical origin. So, the lesion of rosetting was noted on single trees in the varieties of Gala Redi Red, Fujiko, Red Free, etc., and it was a complete defeat in the variety of Piros. A different degree of the manifestation of the disease on the trees was established: from partial manifestation on individual shoots, to aggressive damage to the entire crown of the tree. On young trees bearing fruiting (3-4 years from planting), the rosetting reduces the yield of apple trees by 36 %, ¼ part of the fruits on the trees are small in size compared to the fruits of healthy trees. The infectious nature of the rosetting is confirmed by the transfer of the disease on the most affected Piros variety using summer budding

TO THE QUESTION OF MODELING THE PROCESS OF INTERACTION OF THE ELASTIC WHEEL WITH THE SOIL BASE

abstract 1552001002 issue 155 pp. 13 – 24 31.01.2020 ru 244
One of the most important problems facing agricultural production is to increase traction and energy properties and to decrease the deforming effect of wheel propellers of power tractors on the soil. The solution to this problem requires the widespread introduction of computer-aided design systems, which make it possible to predict the towing, fuel, economic, and agro-technological properties of the tractor unit at the design stage. Traction and energy indicators of wheeled agricultural tractors, the level of impact of wheel propellers on the soil are largely determined by the quality of pneumatic tires. The search for the optimal parameters of pneumatic tires, the compliance of tire characteristics with the parameters and operating conditions of the tractor unit, require solving two main problems. Firstly, the development of analytical dependencies describing the process of interaction of elastic wheels with the soil base, depending on the rolling mode of the wheel. Secondly, bringing to the engineering level the methods of calculation and analysis of the wheel propellers and soil system. The work discusses the issues of physical and mathematical modeling of a pneumatic wheel and soil system. It is noted that among the existing approaches to describing the process of interaction of an elastic wheel with soil, it is most preferable to use rheological models that take into account the simultaneous deformation and subsequent restoration of the soil and tire. However, when it comes to the existing models, the formation of the area of the contact patch is associated with a common normal deflection, which is not confirmed by numerous experimental studies. In the present work, the concept of agrotechnological deflection of a pneumatic tire is introduced. The developed model makes it possible to calculate the rut dept, the tangential and radial deformations of the tire, the longitudinal and normal deformations of the base, and the contact pressure under a known normal load on the wheel, wheel rolling radius and speed. We have also presented analytical and experimental dependences of the contact pressure and the rut depth on the size of the agrotechnical deflection

RESULTS OF RESEARCHES OF THE POSSIBILITY OF VIBRATION GRAIN SEPARATION FROM THE EAR

abstract 1552001003 issue 155 pp. 25 – 42 31.01.2020 ru 256
Enhancing the operative parts of a threshing mechanism which are realizing direct mechanical impact on an ear and being in it grains it is impossible to achieve the considerable lowering and to completely exclude traumatizing grain. New methods of noncontact grain separation from an ear in case of the threshing need to be developed. These methods exclude direct mechanical impact of operative parts on grains. A perspective method of noncontact grain separation from an ear is the imposition to a culm with an ear of oscillating motion, perpendicular its axes. It is a resonance in different parts of an ear can cause. As a result of the pilot and theoretical studies it is set that when impart low frequency oscillations in the range 18…100 Hz corresponding to natural frequencies of its oscillations to a culm with an ear, it is possible to achieve corrupting of the ear or its separation from the culm as a result of a resonance. But grain separation, at the same time, does not come from an ear as the range of natural resonance frequencies of grain oscillations does not match the range of natural frequencies of a culm with an ear and has higher values. The analysis of results of theoretical researches shows that for noncontact grain separation from an ear without its traumatizing is the imposition to it high-frequency oscillations in the range 100 … 14000 Hz matching its natural frequencies of oscillations, which is proved to be perspective. The occurring resonance causes origin of own movements of grain that leads to its separation from the ear
