Unfavorable changes in exchange rates, sanctions restrictions on the supply to Russia of spare parts necessary for the repair and maintenance of previously imported equipment have led to a significant reduction in the service life of imported machinery and equipment. For the solution, the authors propose to implement the strategy of retro-innovations providing the development of new technologies maintaining in working condition of machinery and equipment in conditions of shortage of spare parts and consumables. To do this, it is necessary to develop technologies for the restoration of complex technical devices in order to extend their service life under the restrictions created by the financial market and sanctions policy. The study of the problem was carried out on the example of the operation of trucks of foreign production, the evaluation of engine life and analyzed the structure of the market. On the basis of the obtained results, a model was proposed, on the basis of which it is possible to form a plan for the production of spare parts for high-quality engine repair by domestic enterprises. The strategy of retro-innovations does not solve all the problems of import substitution, but it allows to increase the level of economic security of strategically important economic activities, it creates jobs and provides an opportunity to significantly extend the life of expensive and complex technical devices
This article presents the results of studies on the influence of the fertilizer application rate and methods of using Bereke GN growth stimulant on the biochemical and economic indicators of early potato harvest in southern Kyrgyzstan. Due to the lack of scientific data of complex use of fertilizers and growth-stimulators in the conditions of the Southern Kyrgyzstan, we considered it necessary to specify ways and rates of application of a growth stimulator Bereke GN by production of early potatoes in plain zones on typical gray soils. In the conditions of the South of Kyrgyzstan similar researches in the production technology of early potatoes are conducted for the first time. Field experiments are made on a plot of the Osh technology university in the Kyrgyz Republic Osh region Aravan district Mangyt village in 2016-2018. Complex use of a growth stimulator Bereke GN on crops of early potatoes in a growing season promoted increase in accumulation of starch in potatoes tubers. The analysis of these experiences shows that in options on routes of administration of a growth regulator Bereke GN accumulation of vitamin "C" in tubers in all three years of carrying out researches not considerably raised and averaged 15.98-16.66 mg of %. Concentration of nitrates in tubers of early potatoes, in the conducted researches did not exceed the number of maximum allowable concentration. Economic effect showed, experience option complex uses of a growth-promoting factor of Bereke GN. Therefore, at the same time high net income – 199.18 thousand som/hectare is gained, and profitability equaled 124.13%

The work is devoted to studying the nature of the influence of individual abiotic factors of the southern territories of Russia on the features of the formation of an economic apple yield in adjacent years and the justification of the possibility of adjusting the course of this process in adverse environmental conditions. The studies were carried out in 2018-2019, which are distinguished by the manifestation of weather anomalies in the summer-autumn period. Field experiments were performed at the farms of the Kuban horticultural zone on soils suitable for planting fruit stands: leached and typical chernozems. The features of the development of plants of apple trees of winter varieties Kuban crimson and Fuji on the stock M9 were studied. In the experiments, an option is provided using foliar treatment of plants with Pomaset fertilizer. The effectiveness of the formation of the economic apple crop depends on the biological characteristics of the used pomological variety, as well as the temperature and moisture conditions during the growing season of the plants. Soil conditions do not significantly affect the course of this process. The probability of losing the potential apple crop at the XII stage of organogenesis (pre-harvest decay) under the influence of abiotic summer stressors: high air temperatures and water deficiency is noted. With the manifestation of extremely high air temperatures in late summer and during the autumn months, a significant increase in the duration of vegetation of various (especially strong-growing) apple varieties was recorded, causing a shift in the process of differentiation of generative buds (stages III-IV of organogenesis) to a later date, and, as a result, - decrease in potential plant productivity in the next season. With the manifestation of abnormal weather conditions, the prospects of foliar treatment of trees in the second half of the growing season with Pomaset fertilizer, which optimizes the fruiting of the apple tree in adjacent years, are shown. At the same time, the fruit yield in the current year is increasing by 9-14%, and in the next season - by 7-10% in comparison with the control values
Common lilac (Syringa vulgaris L.), is one of the most essential landscape plants throughout the whole cool and temperate region and also in Finland very popular and traditional ornamental. The diversity of the lilacs available for research use and growth in Finland could be broadened by introducing Russian winter hardy cultivars to Finland. Their winter hardiness and survival in the Finnish climate has to be studied in order to proceed to using Russian cultivars in the Finnish climate. Lilacs that grow at the Central Siberian Botanical Garden Siberian Branche of the Russian Academy of Sciences at Novosibirsk were introduced to Finland within the framework of the collaborative project in 2012. Currently, the collection of Syringa vulgaris in CSBG SB RAS has 26 cultivars of 116 tested ones, most resistant to the conditions of Novosibirsk city. In project “Syreenimaja” (2016-2018) small scale plantations with Russian lilac cultivars were made at several locations in Finland and the freezing tolerance of the cultivars was tested. The survival and growth of the lilac plants in these plantings in landscape gardening areas in old gardens is being observed. The lilac plants are still young and have not been flowering broadly. The preliminary results have shown that the Russian lilacs have potential to grow in Finland, but at least cultivar ‘Daphna’ has suffered from winter injuries. Descriptions of 10 tested lilac cultivars from the collection of the CSBG SB RAS are given
The study was carried out with the financial support of the RHNF as part of the research project of the RFBR 17-02-00475-OGN "Application of metaheuristic algorithms for solving direct and inverse problems of optimizing the management of spatially distributed complexes"). The article considers the issue of automated selection of specialists for the project. It is proposed to use artificial neural networks as a decisive core of the system. We have considered several solutions to the problem with a basic version based on a cascade of two neural networks
Slope land (ravines, gullies, mountain areas) for many countries of the world are important areas of economic activity, and for some they are the only living space. In the mountainous areas there are cereals and feed, fruit, citrus, nut, berry and essential oil crops, grapes, tea and many others. On slope lands, soil preparation by terracing is widely used. The article considers modern technologies and machines for the construction of terraces in order to create protective and fruit plantations on them and to involve new areas in agricultural turnover. There are two main ways to create terraces: hinged and rifled. Most often, when terracing on tractor-passable slopes, various plows and graders (floor terraces) are used, and on tractor-passable slopes there are universal bulldozers and terrasers (rifled terraces). The shuttle plow PCHS-4-35 and revolving plows are especially convenient for the device of floor terraces, with the help of which it is possible to significantly increase labor productivity by reducing the time for idle runs. For rifled terraces, we use a large complex of machines, the most productive of which are: terraser-Ripper TR-2A; terraced equipment TK-4; terraser T-4M, etc. The use of the proposed complex of machines in the construction of raised and rifled terraces will help to increase productivity and involve new lands in agricultural turnover, which will ultimately increase food security of the Russian Federation
The small-scale intra-economic plants producing loose compound feed are outdated and require reconstruction by method of the modern process lines of compound feed granulation or extrusion adding. But such reconstruction requires a production stop. It is unacceptable for agricultural enterprises. The method of small-scale intra-economic formula-feed plant reconstruction is offered. The method consists in integration into composition of the plant of a modular process line for loose compound feed extrusion or granulation without stopping of production. The building for a new process line is created from the constructive modules representing metal frames with overall dimensions of a standard cargo container in which the equipment, ready to application, is installed. The combined multilevel building of a process line for granulation or extrusion is placed near the main factory building of the existing intra-economic enterprise. Buildings additional and the main production lines form two multilevel production factory building. The example of small-scale formula-feed plant reconstruction by method of integration a modular process line for granulation is explained. The line consists of modules for operational storage and dispensing of loose compound feed, conditioning and granulation, cooling, separation of granules. The traditional formula-feed plant of the fixed structure turns into the transformed system because the configuration of the new modular line can be easily
changed. The offered method of reconstruction is perspective for application on small-scale intra-economic formula-feed plants as allows to reorganize without stopping operating production preparation of compound feed according to the modern requirements, having increased its quality and period of storage. Period of construction of the plant decreases from several months to several weeks thanks to creation of the building of the new line from ready constructive modules
The article provides an overview of domestic and foreign patent information on existing recipes and methods for producing complex feed additives containing probiotic microflora for cattle. Introduction of probiotic cultures of microorganisms to feed additives, along with biologically active substances, allows us to influence the processes of microbiocenosis of the intestines of animals, and, therefore, digestibility and digestibility of feed, which, in turn, leads to an increase in animal productivity. In addition, probiotic cultures contribute to the biodegradation of mycotoxins, which helps prevent mycotoxicity of animals. The most popular in modern livestock breeding are complex feed additives with broad-spectrum probiotic preparations, performing various biological functions
The quality of the seed largely depends on the value of the future crop. For sowing, it is necessary to use seeds with high sowing qualities. This article is devoted to the study of the formation of high-quality seed of new varieties of winter barley, depending on the controlled compaction of crops. The paper describes in detail the importance of sowing qualities of seeds for the formation of high productivity of barley crops. The questions of influence of different seeding rates on laboratory and field germination of seeds are considered. The correlation between the four variants of seeding rates and field and laboratory germination was determined. The purity of seeds of winter barley varieties Kubagro – 1 and Kubagro – 3 was studied and it was determined that the change in the density of the formed stem does not affect the purity of seeds of these varieties. The use of highly productive seeds for sowing and further qualitative cleaning of the obtained grain contributes to the production of seed material with high purity. When considering the weight of 1000 grains in the studied varieties, it was determined that with an increase in the number of productive stems per unit area and a decrease in the area of plant nutrition, both varieties reduced the mass of grains. The highest rates of weight of 1000 grains were determined when sowing with the norm of 3.5 million germinating seeds per 1 ha, such a pattern was observed for both varieties
