The article discusses scale formation problems of greenhouse complexes with geothermal heat sources. Two-circuit geothermal heat supply systems with intermediate heat exchangers are used to prevent equipment and communications scale. Fresh softened water is heated by geothermal heat and is supplied to consumer needs. The heat exchanger and primary circuit communications contacting with the geothermal heat carrier (geothermal water) are subjected to scale formation in the existing system. A scale formation of heat exchange surfaces reduces the efficiency of the heat exchanger and requires a periodic cleaning and causes a chain of economic losses in the production, transportation and consumption of heat. Currently, we use physical, chemical, biological and combined methods of scale formation prevention. The article also considers hypothesis about the effect of an acoustic-magnetic field on solutions. It was found experimentally, that the acoustic-magnetic field affects to characteristics and dimensions of salt crystals. The number of particles increases and solid phase dimensions decrease. A large number of microcrystals suspended in water are formed as a result of the nonchemical acoustic-magnetic treatment of geothermal water. These crystals do not stick to the pipe surface and do not settle to the bottom, may be filtered out and carry out by water flow from the system
The article reports in color on the characteristics of the three varieties and their clones that are common in Afghanistan. In the process of ampelographic screening of vineyards in Afghanistan, three varieties previously undescribed in Russian literature under the local names Aita, Gundyan and Shandyhani were discovered. Their identification by ampelographic and ampelometric characteristics made it possible to establish the original Aita variety, the Gundyan variety as a synonym for Guladan and Shandyhani as a synonym for the world famous Sultanin, or Kishmish. The described varieties are quite common in Afghanistan, reputable in economic returns and are still promising for cultivation in their country, where they are successfully used in the manufacture of dried products and high-quality diet juices. To identify the impact of various environmental conditions on the growth, development, quantity and quality of the crop, these varieties must be tested in all zones of different ecological and geographical areas of cultivation
The aim of the following research is the studying of the efficacy in probiotic drug Probiolact (0.5% and 1.0%) usage, being in combination with Milkshake supplement. The given complex mixture is meant for medicative-phylactic purposes focused on the reduction of young ones death rate owing to gastro – intestinal diseases when neo-natal period. It is specified that the above-mentioned mixture affects the livestock indices. Thus, the average growth of baseline for the period of 30 days experimenting has been 7.4 kg, whereas in 2 tested groups it accounted for 10.3 kg and 11.6 kg, consequently. Therefore, the best possible daily phylactic doze of Probiolact (1%) and Milkshake mixture demonstrates the positive effect on the pro-cess of bifido- and lactoflora formation in calves’ intestinal tract due to normal flora cells quantity increase. With that, intestinal tract contamination level of disease-producing flora gets lower, and the natural resistance of cell-mediated immunity grows. Thus, two major problems of factory farming (i.e. the reduction of young death rate and surplus guarantee) can be solved with giving calves the mixture to drink, along with the first portions of colostrum, and during the following 30 days
The problems of automated control of the technological processes of crop production and the tasks of supporting the adoption of managerial decisions at each stage of the production cycle have become even more urgent in view of the processes of transformation, globalization and digitalization of the economy, which have recently become widespread. The agricultural sector of the economy of the Russian Federation is no exception, because agricultural products, especially crop production, are of strategic importance and are the basis of food security in our country. In this scientific project, the problems of agricultural enterprises of the Krasnodar region, in particular, in the field of management processes, its information and software, were investigated. At this stage, it was determined that the measures taken to increase labor productivity at the agricultural enterprises of the Krasnodar region and the automation of technological processes in crop production were not complex, therefore, they had a slight effect on the efficiency of the industry. Studying the IT services and software market made it possible to draw a well-founded conclusion that decision-making support processes in crop management, especially issues related to the justified choice of crop cultivation technology, rationalization of a crop rotation system, analysis of a history book of crop rotation fields, calculation of dosages of organic fertilizers for a deficit-free balance of humus, are not covered by the funds of software systems offered on the market. As a result, the demand for industrial analytical systems and, in particular, integrated automation systems for managing crop production processes for agricultural enterprises is forming in the software market. Therefore, the development and implementation of a computer decision support system for managing crop production processes, based on mathematical models for analyzing and evaluating the economic efficiency of crop cultivation technologies, crop rotation rationalization models, data analysis models for crop rotation field history books, models of optimal selection of crop protection products plants and fertilizers has become very relevant. These studies can be considered priority and highly demanded, as they are directly related to one of the fundamental directions of the modern development of agricultural production - the study of the problems of development and implementation of an integrated automated information system for crop management. The article is devoted to the theoretical justification and feasibility of the practical implementation of the software module for accounting and analysis of data from the e-book of the history of crop rotation fields, which is part of the developed automated crop management information system
The article provides a convincing argument for the preference of wool and fur products over artificial and synthetic textile fibers. It is noted that artificial fibers and synthetics have negative ionization, while natural wool has positive ionization. It is emphasized that negative ionization is far from harmless to humans. The analysis of the state of sheep breeding in the Russian Federation is given and this industry in the Rostov region is characterized against this background. The data on the number and productivity of sheep of the main age and sex groups, the production of young animals per one hundred ewes are presented. The characteristic of tribal resources of the country and region is given. The breeding base of the industry in the Russian Federation is represented by 205 breeding organizations, including 3 breeding and genetic centers, 44 breeding plants, 145 breeding reproducers and 13 gene pool farms, which contain 1389.8 thousand sheep (39.0 % of their total number in agricultural organizations and 6.6 % of the sheep population in farms of all categories), including 904.7 thousand Queens (35.0 and 6.2%, respectively). The breeding base of the Rostov region has eleven farms, of which 6 breeding plants for such breeds as the Soviet Merino and salskaya and 5 breeding reproducers. In addition to these breed resources, there are breeding reproducers for the qigai and edilbaev breeds in the region. Total number of breeding sheep in the region is almost 44 thousand. The article indicates main problems in the development of the industry and ways and means to solve them
Pneumatic grain seeders with a central dosing system have high productivity due to the presence of a large centralized hopper, as well as a large width of capture. However, they cannot always ensure an even distribution of seeds between coulters. The article performs an analysis of designs of sowing machines. The influence of the angle of rotation of the air mixture in the tap on the drop in seed speed is studied. We also obtained the equation of seed velocity at turns of pneumatic lines of pneumatic seeders. Branches were analytically studied, the outer walls of which were described by various equations in a rectangular coordinate system. Optimal are bends, the contour of the outer wall of which is outlined by the curves of the power function. Analysis of such curves indicates that the optimal curve that provides the smallest meeting angles is a cubic parabola. Based on the considered analytical materials, we found that when developing a pneumatic scheme for transporting seeds of grain crops to the distributor, it is necessary to avoid using taps with horizontal to vertical and from vertical to horizontal
The article defines the importance of growing potatoes in the Bryansk region. We carried out spatio-temporal re-search of the condition of the industry and identified key shifts in its development over the past 10 years. The pro-portion and its shifts were showed as well. We calculated ranking of administrative areas for potato production in general and by individual categories of farms for the period from 2008 to 2018. It allowed us to find out rates of spatio-temporal movements. The analysis showed increase of concentration and differentiation of growing potatoes in the region
The article deals with the complexity of the construction of engineering theories in both scientific and practical direction based on the use of non-traditional approach to the problems of effective data monitoring, especially in the field of control systems of multicomponent representation of objects of system analysis. The study of the complexity of this issue involves a detailed consideration of the relationships of the elements of these objects on the basis of known methods, while the integration of heterogeneous knowledge obtained by such often independent methods becomes very time-consuming and poorly formalized. Currently, the processing of information and its subsequent presentation have changed significantly through the use of data mining (IAD), which includes not only the organization of the knowledge system in various missile defense, but also in the field of DSS. This, in turn, contributes to the effective formalization of fuzzy information and processing it in the form of fuzzy algorithms, which is an extension of the decision support system based on fuzzy logic – DSS NL. At the same time, it is necessary to emphasize the features of the proposed approach of the DSS NL, which is that it can be used in various missile defense systems, including for the effective analysis of statistical information of multicomponent representation of objects, which is used in determining statistical indicators to identify and assess existing and potential risks, adverse situations, as well as in the preparation of motivational grounds for managerial decision-making. For the purpose of more detailed establishment in real missile defense of the relations between objects it is offered to carry out by means of various degrees of dependence. For example, the types of graded connections are considered as fuzzy objective connections, and the use of expert systems and semantic links led to the construction of hypotheses analysis of situations and semantic relationship between them. A significant difference of the considered DSS NL is that each model is formed on the basis of a separate semantic network, and the system itself works with several models of Pro related or unrelated to each other. On the basis of the use of the concept of the relationship of proximity between concepts, belonging to the situation, its information part of the recommendations Are grouped according to the selected situation for their subsequent analysis and decision-making. On the basis of the principle of coordinating actions and construction of the function, taking into account the optimal time of the control action, the General algorithm of decision support for emergency production situations in the Pro low-rise construction, both in urban and rural areas
The article provides an overview of the results of the study of the growth and development of corn in the conditions of the northern zone of the Krasnodar region, depending on the density of plant standing and seed dressing. The object of research was an early-ripe hybrid of Ross 199 corn. Two factors were studied in the experiment: factor A - plant stand density (60, 70 and 80 thousand units / ha), factor B - seed dresser (Maxim XL (k) and Maxim Quatro). The studies were carried out in accordance with the thematic plan of scientific research of the Department of General and Irrigated Agriculture of Kuban State Agrarian University. The total area of the plot is 1008 m2, the accounting area is 672 m2. The number of rows in the plot is only 8, including accounting - 4. The arrangement of the plots is systematic. Three repetition. The predecessor is winter wheat. The calculations and observations in the experiment were carried out according to generally accepted methods. The technology of growing corn in the experimental plot corresponded to generally accepted for this zone and culture. The predecessor is winter wheat. Our studies have found that the leaf area was largely influenced by the density of plant standing – with the thickening of crops, it decreased by 2.9 thousand m2 / ha or 28.7 %, and there were practically no differences in the leaf area between different variants of seed treatment. Corn plants increase the accumulation of dry matter throughout the growing season. With an increase in the density of plant standing, the accumulation of dry matter decreases, and the studied protectants do not affect this indicator
In the article we performed an analysis and generalization of the accumulated results of scientific research and best practices in the problem of creating and using machines and technologies in field cultivation of the Krasnodar region; their shortcomings are revealed, as well as ways and means of increasing the efficiency of field crop production through innovative technology machines. Attention is paid to eliminating the violation of agrotechnical, environmental requirements, complexity and quality work performed by serial equipment; unreasonably dependent nomenclature of technical means and high labor costs and means compared with foreign technologies, proposals have been developed for a system of machines for mechanizing field cultivation, which includes the I450 mobile power tool, Belarus tractor 1523 and 890, the fertilizer sprayer TUNAN-1, E5-1, KZR combines -12 and CF-10, a fundamentally new loop of cars for mobile power is based on multifunctional units, assembled from serial single-operation machines according to the inventions of KubSAU, and machine technologies based on the use of multifunctional units strictly comply with the farming system and the fulfillment of the above requirements. The transition of agricultural enterprises to new technologies for the production of field products is justified, including a “non-spring” for cereals, legumes and oilseeds, a new system of tractors and trailed combines that are not inferior to self-propelled, but much cheaper. The new mechanization system provides a breakthrough in the efficient production of crop production in accordance with the estimated technical and economic indicators
