abstract 1351801030 issue 135 pp. 223 – 237 31.01.2018 ru 338
The results of a comparative study of the experimental groups of Holstein animals belonging to the Vis Bey Eidial line are given: four groups of repair calves and four groups of gobies. Their hematological indices were studied at higher daily rates of milk drinking and early training of experimental animals to plant feeds with a probiotic supplement of cellobacterins in the milk period. The difference between the groups was the technology of their cultivation: I-control group - up to 6 months of the age was grown according to the traditional technology adopted in the farm: 200 kg of milk (for 50 days) and 400 kg of return (from 50 to 110 days), and concentrated feeds consisting of pre-fodder (50%) and corn (50%), the same calves received experimental calves; II-test group - up to 6 months increased norm of milk drinking (for 25 days) - 200 kg and 400 kg of return (from 25 to 60 days); III-test group - up to 6 months the increased norm of drinking milk (for 50 days) - 450 kg and return (from 50 to 110 days): heifers - 600, bulls -800kg; IV-test group - up to 6 months an increased rate of milk drinking (for 60 days) - 450 kg and return (from 60 to 120 days): heifers - 600, bulls -800 kg. The calves of all experimental groups were fed a probiotic preparation of cellobacterin in an amount of 3 g for each animal up to 18 months of age. When the experimental animals reach 12-, 15-, 18-months age, hematologic examinations were carried out. It has been established that with the age of experimental animals, metabolic processes are intensified, the change of which was influenced by the use of different norms of drinking milk during the milking period, using a probiotic

TEMPERATURE REGIME OF THE TREATED SOIL LAYER

abstract 1461902012 issue 146 pp. 49 – 57 28.02.2019 ru 338
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 -40S to + 85S with a measuring accuracy of ±0,6S. 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 23,8S a standard deviation of 3,1S. 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 (21,2S) 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

VISUAL GRAPHICAL ANALYSIS OF PERFORMANCE INDICATORS OF INTEGRATED PRODUCTION SYSTEMS OF SUGAR SUBCOMPLEX AIC (PART 1 – FORMULATION AND SIMULATION)

abstract 1221608042 issue 122 pp. 596 – 622 31.10.2016 ru 337
The article deals with methods of visual-graphic analysis (technical analysis) and a possibility of adapting them to the conditions (indicators) of the sugar subcomplex from the position of integrated production systems (IPS). It should be noted that technical analysis is very popular. Thanks to the advent of powerful processors for computers and inexpensive software, trade analysts have access to technical analysis tools. The topic is becoming increasingly relevant in connection with the high pace of the global economic community. Visual graphical analysis (technical analysis), as well as its latest methods (indicators) that are adapted to modern economic conditions, are sort of the primary "blueprints" for the more complex forecasting tools, without which none of the analyst can do. Separating statistics from mathematics as an independent unit occurred after the development and start of mass use of tools visual graphical analysis (VGA) in various applied Sciences. The main feature of the prediction is the decision of the tasks, which are implemented in the algorithm of sequential nonparametric model. This indicates the improving the validity of information when predicting performance of IPS SP AIC. For a more General (objective) picture of the forecasting activities of IPS SP you need to apply this analysis in combination with other tools, such as hierarchical analysis of structural change and of correlation and spectral analysis. According to the forecasts obtained with the help of the indicators VGA, countries such as Brazil and India over time, waiting for the "overheating" of the economy due to unprecedented growth in the volume of growing sugar cane and manufacturing raw sugar. However, it is not necessary to consider the visual-graphic analysis as a perfect tool for forecasting market trends. Technical analysis should be seen as a tool for analysis and forecasting, which uses as the basis for short-term forecasting (benchmark) for operational decision-making by managers as a major sugar holdings, and the Ministry of agriculture

EROSION ZONING OF THE TERRITORY OF THE BRYANSK REGION: THE EXPERIENCE AND CONTEMPORARY PROBLEMS

abstract 1281704092 issue 128 pp. 1309 – 1319 28.04.2017 ru 337
The article analyzes the experience of zoning of territory of the Bryansk region on the main factors of erosion to select the measures to combat it. The Bryansk region in its present borders, mainly representing the middle course of the Desna river, has been considered safe in relation to erosion. The existing zoning is based on the quantitative characteristics of the processes of erosion that primarily allowed us to assess the scale of their impact on nature and the region's economy. The erosion zoning was performed on the basis of the map of erosion-prone land. As a result of study and analysis of all natural factors of erosion and land of the region under study the regularities of distribution of land erosion and intensity of spring rainfall and soil erosion are detected. Under the leadership of Filin V. I., a survey of the ravines of the region was conducted and made the scheme of erosion zoning, according to which the region is divided into three areas. It is noteworthy Horinas E. V. research. When divided into areas it was taken into consideration the need for each of them specific actions to combat the causes and consequences of erosion in relation to the peculiarities of the latter in each district. According to the intensity of the erosion processes and physico-geographical zoning of the Bryansk region and the nature of agricultural land use, specialists of the Bryansk branch of the Institute "Rosgiprozem" produced erosion zoning of the territory of the region, which highlighted seven erosion regions. From the variety of methods for zoning, the most appropriate in our view are created, based on the estimated small-scale (medium-scale) maps of erosion of land, capable of performing the function diagrams of erosion zoning

abstract 1311707057 issue 131 pp. 672 – 683 29.09.2017 ru 337
In the conditions of middle valley of the Lena River on the cryogenic, inundated, cespitose and chernozemic soils different steppe communities differently react on dietary regime. Herb-grass phytocenosis at organic dietary regime is reformed in cereal phytocenosis with the contents of cereals to 76% and bean types 19% of dry basis with productivity to 20 centner of hectare of dry basis. At the same time the efficiency of the improved phytocenosis was on charge exchange energy of 17,3 mega joule of hectare, feed units 1032 and a crude protein of 247 kilo of hectare. The whetgrasses phytocenosis has provided productivity to 19,4 centner of hectare and the content of perevarimy protein in 1 feed unit up to 118 gram. So the most effective for the steppe meadows is using complex fertilizer (humus of 20 tons of hectare + N60P60K60), increasing the productivity twice with a high quality of food

COMPARISON OF SPECTROGRAMS OF THE MOST ACOUSTICALLY LOADED MODES OF OPERATION OF HARVESTERS

abstract 1211607078 issue 121 pp. 1255 – 1290 30.09.2016 ru 336
Nowadays the method of finite elements (MFE) is a standard method of acoustic analysis. It consists in finding the solution of the function on the maximum allowable quantity of piecewise continuous functions that are determined in allowed number of subdomains. The number of sub-domains has a finite value but an unknown continuous value is approximated by the polynomial on each element that acquires specific values in the nodes. Polynomials can be various but all of them produce continuity of total value along its limits. Herewith because of technical features of the calculation process minimization of numbers of polynomials is required according to the criterion of acceptable precision. In the chosen COMSOL Multiphysics program model the range of frequencies under analysis is the result of the sum of 10 segments (sub-ranges). Such a sub-range is a minimal discrete value in certain conditions of calculation. Thus, the calculated value on this subrange can be considered as the result of calculation by means of using the band-pass filter with 35 Hz bandwidth. Because of this, we can draw a conclusion about changing the state change of the noise exposure on the combine operator with respect to the previous measurement according to the regulatory methodology. Hereinafter if the stated change of the noise exposure is found, measurements that are more precise are taken. On the basis of these measurements the head of the company receives recommendations either on verification of stated acoustic characteristics of devices and mechanisms of a harvester or on verification of acoustic ways of transmission of structural noise (noise created by devices that penetrates into the booth through the combine body), or on verification of noise isolation of the booth

PERSPECTIVES OF SYSTEM-INFORMATION APPROACH TO THE FORMATION OF QUALITY OF FRUITS AND VEGETABLES DURING HARVESTING, TRANSPORTATION AND STORAGE

abstract 1231609057 issue 123 pp. 841 – 855 30.11.2016 ru 336
In the study of the processes of growing, harvesting, post-harvesting processing and delivery of fruit and vegetables it seems to be rational to have generalized control of the "product – environment – packaging – transport - storage" in general, as well as providing the possibility of creating optimal conditions for fruit and vegetable products depending on its condition. The basis of ensuring product integrity at all stages of production is a system approach with application of modern information technologies. Optimization of logistic processes in the agro-industrial complex (AIC), in addition to cost, market influences many important indicators of the final product of this complex: quality, timing and reliability of supply, the size of the delivered batches, etc. The quality of fruits and vegetables begins to change dramatically immediately after harvesting. Being in a stressful and unfavorable conditions, fruit, vegetables, root crops intensively lose moisture and consume nutrients, secrete aromatic substances, carry out the breathing process. These losses are caused by biological factors fit fruit and vegetable products to the changed conditions. Thus, the main indicators of the quality of products to control rationally in the process of harvesting and subsequent production phases take into account the data obtained to optimize process parameters to reduce losses and damage products. The article discusses the prospects of applying the system-information approach to the formation of quality of fruits and vegetables during transportation and storage. The proposed embodiment of a generalized control of the "product – environment – packaging – transport - storage", aimed at ensuring the possibility of creating optimal conditions for easy-to-sell agricultural products (fruits, vegetables, root crops) depending on its condition. We have established that rational technology of production and sales of products must have the ability to control and operational adjustments depending on the level of quality input products from the stage of harvest
