05.20.00 Processes and machines of agroengineering systems
05.20.00 Processes and machines of agroengineering systems
Description
The article presents the results of studying the influence of the method of treatment before storage and storage parameters, including the relative air humidity, on the value of general losses of carrots. The taproots treatment before putting into storage was carried out with electromagnetic fields of extremely low frequency and the bio-preparation Vitaplan. After treatment, the taproots were kept at a temperature of +2±1°С for 56 days and +25±1°С for 21 days. In the process, the relative air humidity was changed from 40 to 90%. At a storage temperature of +2±1°C, the lowest total loss was observed at a relative humidity of 90%. At a storage temperature of +25±1°С, the optimal, from the point of view of decreasing the general losses, turned out to be the relative air humidity of 70%: with decreasing relative air humidity to 40%, significant increase of natural losses was observed, because the taproots were losing water intensively, and with increasing relative air humidity to 90%, favorable conditions were created for the growth of pathogenic microflora, which caused significant losses from the microbiological decay. The method of pretreatment of carrot taproots, providing the lowest general loss during storage in all the studied conditions, was joint treatment with ELF EMF and the bio-preparation called Vitaplan

FEATURES OF TECHNICAL RISK ASSESSMENT UNDER NON-DETERMINISTIC STOCHASTIC PARAMETERS
05.20.00 Processes and machines of agroengineering systems
Description
The article considers a variant of parametric representation of a complex product of single use in the process of its creation during tests, when structural failures of the product or its components in one or more parameters specified in the technical specification require modifications leading to a change in the general amount and repeating of the tests, but it is possible to reduce the volume of tests by taking into account a priori information. This is especially up-to-date while ensuring the reliability of complex single – use products, the components of which are first stages of ground tests, and only then as part of complex products-the stages of flight tests. Structural failure of any component of such a product at the stage of ground tests does not lead to such consequences as if it occurred during flight tests as part of the product. Meanwhile, the refinement of the component element of a single-use product, the structural failure of which occurred at the stage of flight tests as part of the product, and the assessment of its effectiveness, can be carried out at the stage of ground tests, in the case of consideration of a complex product in parametric form. This can significantly reduce the cost of flight testing of a complex product, in the case of effective completion of the component element of the product at the stage of ground tests, without a significant (temporary) decrease in the overall reliability of a complex single-use product

05.20.00 Processes and machines of agroengineering systems
Description
New ways of solving reducing soil compaction problem are substantiated. Soil compaction destroys its structure, violates its water-air regime, and leads to erosion and reduced yield. The effectiveness of the presented directions, based on the analysis of the issue and the results of own research is confirmed by practical use in the crop production processes mechanization of intellectual engineering authors' developments, based on their inventions and well-known serial technology selected from Automated reference system "agricultural machinery". It was the synthesis of own research results and modern agricultural machinery best samples analysis that allowed us to form an effective system of machines that reduce the harmful soil compaction. This ensures soil fertility preservation and crop yield increase. The set of machines proposed in the system for soil processing, sowing, fertilizing, spraying and harvesting not only reduces soil compaction but also improves work quality, labor productivity and complexity of the work performed, harvest and reduces costs of all types (energy, money, labor). The basis of the problem solution consists of a combination of technological operations for one pass of the unit across the field, multifunctional units application in the system that performs tillage and seeding, fertilization and tillage, additional fertilizing of spike crops with simultaneous harrowing, harvesting with simultaneous stubbling or straw pressing etc., refusal to use heavy machinery in the fields, trucks, conversion tracked system on tractors, front and rear hydraulics for making multi-functional units, the use of fundamentally new machines and adaptations to them according to the inventions of the authors

Description
The analysis of varietal and age structure of vineyards occupied by 29 varieties and clones of the technical direction of use in the "Alushta" branch of FSUE "PJSC "Massandra". Taking into account the ecological and climatic conditions of the Alushta valley and the specialization of the economy, the largest share in the assortment of technical varieties is occupied by red grape varieties: Cabernet Sauvignon and clones of Cabernet Sauvignon R5, R8, VCR8, No. 169 including (26.68%), Bastardo Magarachsky and Bastardo clone VCR1 (12.06%), Saperavi (7.33%), Krasnostop zolotovsky (5.69%), Merlot and clone Merlot R3 (4.62 %). White varieties are in a smaller percentage: white Muscat and white Muscat clone R3 (8.47 %), white Kokur (7.1%), Aligote (3.82%), Semillon and clones Semillon № 173 and № 299 (3.68%), Gars level (2.99%). Plantings in the most productive age of 6-10 and 11-15 years are 57.5 % of the total area. At the same time, the share of introduced clones of varieties accounts for 26.65 %. In general, the age structure of the vineyards is favorable. The company produces high quality wine materials for production of traditional Federal state unitary enterprise "PJSC "Massandra" wines: white Port Alushta, Alushta red Port, pink Port Alushta, Alushta red Table, Pinot Gris, Massandra, Madera Crimean Alushta Tokay, white Muscat, Massandra Kokur, Semillon Alushta and sherry wine. In addition, there are new brands of semi-sweet white and red wines Pearl Massandra, as well as varietal wine materials Aligote, Cabernet, Sauvignon, Merlot, Saperavi, Chardonnay, Bastardo and Semillon. Analysis of the assortment shows that in the production plantings of "Alushta" branch of FSUE "PJSC "Massandra" there are varieties of medium and late ripening, which does not create peaks during harvesting and processing, ensuring uniform flow of raw materials for winemaking. It is necessary to expand the assortment of the economy due to a number of promising varieties of Syrah, Petit Verdot, Malbec, Sangiovese and others with a complex of economically valuable properties introduced from other regions

TEMPERATURE REGIME OF THE TREATED SOIL LAYER
Description
The article discusses the influence on the thermal regime of soil by agricultural activities, as well as the results of studies on determination of temperature in different soil layers under conditions of insufficient and unstable moistening of southern Russia. Experiments were performed in the experimental field in FSRI of the «ASC «Donskoy» (Zernograd, Rostov oblast) in terms of long-term stationary experience in the cultivation of soybeans with different technologies (traditional, zero). We performed the soil temperature checking at a depth of 30 and 60 cm using the temperature sensors with a measurement range from -40S to + 85S with a measuring accuracy of ±0,6S. For accumulation of data were used in the logger (weather station) Watch Dog 1400 series Micro. The purpose of the research was to determine and compare the influence of technologies of processing of soil on the temperature of the soil at different levels. On the basis of the conducted researches it is established that the average value of the ambient temperature stood at 23,8S a standard deviation of 3,1S. These figures are higher than the temperature of the soil at the background processed by traditional technology, and the raw background. The lowest average soil temperature at a depth of 30 cm (21,2S) recorded at zero background, obviously due to the presence on the soil surface of plant residues that protect the soil from solar radiation. Thus, the soil as a dynamic system converts the input signal (the ambient temperature) so that it is reduced in size and the rate of change (dynamic). These soil characteristics are determined by the technologies of soil processing

Description
The problems of crop management and management decision support are still relevant at the moment. Crop production is of strategic importance and is the basis of our country's food security. The use of information technology in agriculture was limited to the use of computers and software, mainly for managing financial transactions and maintaining accounting and operational accounting. It should be noted that the measures taken to increase labor productivity and automate technological processes in the agro-industrial complex did not have an integrated nature; therefore, they slightly influenced the efficiency of the industry and, as a result, the competitiveness of products. Thus, the development and implementation of a computerized decision support system in crop management based on mathematical models for analyzing and evaluating the economic efficiency of crop cultivation technologies, crop rotation rationalization models, data analysis models of the book on crop field history, optimal selection of plant protection products and fertilizers highly relevant. This scientific project can be considered a priority and highly demanded, as contributing to the implementation of one of the requirements of the State program for the development of agriculture and regulation of the markets of agricultural products, raw materials and food of the Russian Federation for 2013-2020. The aim of the project is to improve the mathematical models and methods for managing technological processes at agricultural enterprises through the development and implementation of an integrated automated information system for crop management.
