Fruit growing
and viticulture of South Russia
The introduction of digital technologies in agriculture is becoming relevant, as well as in other industry branches. Dig-ital technology is essential for gardeners to optimize productivity, increase in manageability of horticultural operations, and increase profitability. Currently, in Russia only 10 % of the land is cultivated using the digital technologies, the non-use of new technologies leads to a loss of up to 40 % of the crop. Considering the need to overcome the technological lag behind developed countries, it is assumed that the share of the digital technology market in agriculture will grow every year, and to 2026 the market of information and computer technologies in the industry should grow at least in five times. The Ministry of Agriculture intend to confirm the Digital Agriculture program at the government level for its inclusion in the Digital Economy program. All the achievements in the world in the field of digital technology, from robot-farmers to automated green-houses, may become the part of the future, when in 2050 almost 10 billion people will live on the planet, and therefore the world needs to increase food production to meet needs of the population, and perhaps just new digital technologies will help to achieve this goal. The use of robot technics in the production of fruit crops will lead to the possibility of planting more intensive gardens with a compacted scheme and the corresponding formation of tree crowns for the convenience of managing the processes in the garden, which will ensure high yield. The article presents a brief analysis of literary sources on modern digital technologies and examines the recent global developments in the field of precision gardening and the advantages of their implementation.
The actuality of problem of organic production in the Crimea has been studied based on the results of sociological interrogation conducted using questionnaire method and the current situation with wine consumption in Russia was analyzed, based on available analytical data. The questionnaire comprised the questions on ecological awareness of the population and organic products consumption. It is established that the majority of respondents demonstrated awareness on organic agriculture (69 %) and on the negative impact of pesticides on human health (87 %), which attests to high ecological awareness of the Crimea population, as a whole. Note was made on the high readiness of the Crimeans to buy organic agricultural production grown without pesticides and other agrochemicals, even if it is higher in price. The most acceptable for the Crimeans price adjustment for organic production was established at the rate of 20 %, as compared to non-organic products. A high level of mistrust was revealed for such markings as eco, organic, bio, etc. on the labels, as well as negative correlation between the trust level to labels and ecological awareness of the population as related to the negative impact of pesticides on health (r = 0,19). As a result of questionnaire analysis it is established low level of grape wine consumption among the medium-income population of Crimea (the majority of respondents buy wine once a month at most, if at all), and a high frequency of fresh fruit purchase (81 % of respondents buy fruit once per week or more often). The need to produce the own organic food products in Crimea to increase its touristic attractiveness was noted. The basic products that are the trademark of Crimea, according to the respondents, are grapes, wine and figs.
Organic fungicides of systemic action are applied in the vineyards more than two decades to fight against fungal diseases, which led to the soil contamination of cultivated plantings. In the process of studying their degradation, the toxic compounds were found, which persist for a long time in the soil of agricultural land, and reduce the soil suppression indicators. The organic fungicides of the systemic action of the triazole group (falcon, universal, kolosal, kolosal pro) are unificated by the presence in their composition of the tebuconazole active substance, distinguished by the duration and stability in the soil of the cultivated grape plantings. This fact dictates the need to increase in the suppression of the soil, affecting the detoxification of toxic inclusions. The study of the influence of soil suppression enriched with biologi cal fertilizer from wine-making waste the tebuconazole detoxification is the goal of this work. Tebuconazole residues in the soil were determined according to generally accepted methods using a Color 500M gas chromatograph. It has been established that the treatments of vineyards against fungal diseases with fungicides of the systemic action of the triazole group lead to soil contamination with tebuconazole. Long-term use in the vineyards of fungicides containing a tebuconazole, showed that by the period of the next treatment its concentration in the soil exceeds the permissible rate (up to 7.90 MAC). It was revealed that 2-fold introduction of biomaterial from wine-making waste into the soil of vineyards increases the properties of soil suppressiveness, activating the process of detoxifying tebuconazole from 7.9 to 3.3 MPC. The partial detoxication of tebuconazole has been established by the enrichment of the soil with natural compounds in the form of wastes from the grape industry. The need to use this kind of organic fertilizer as a detoxifying agents require further development of the modification of its functional composition and physical-biochemical properties.
The complex of biologically active substances in fruits and berries of the Kuban, optimally adapted to the Southern climate, allows you to the select the individual crops and varieties with high biological activity, which is characterized by a set of various vital and physiologically significant components that can provide the daily rate of BAS for the human body. Research is carried out of qualitative structure of fruits of an apple-tree and berries of grapes, according to varieties, revealing of the general regularity of change of BAS content in dynamics. Parameters of increase in an allocation of biologically active agents, such as are determined a type of the used raw materials, its extent of crushing, temperature change of processing, selection of processing equipment. Research of chemical indicators of pomace quality from secondary raw materials are conducted in the process of production of apple and grape juice. The effect of the optimal temperature regime 35-40 º of infrared drying apple juice is represented by higher rates of fiber, pectin and minerals. For each type of raw material and conditions of the process, there is a minimum particle size: for apple row material no more than 0,3 mm, for grape no more than 0,4 mm, in which the total internal and external diffusion resistance is minimal, facilitating a more rapid extraction of biologically active substances. Due to optimum selection of processing equipment on a powder production line from an apple or grape pomace, it is possible to adjust the influence of physical and biochemical mechanisms and to considerably reduce the speed of technological process and to increase in the selection of biologically active substances in a digestible form. The results of laboratory research of powder from apple (Prikubanskoy) and grape pressing (Cabernet) pomaces are presented.
When processing grapes in the wine-making and non-alcoholic industry, a significant amount (from 15 to 20%) of waste is generated, the rational use of which makes it possible to obtain additional products of great interest and value for a number of sectors of the national economy. The most important direction of increasing in the efficiency of modern wineries is the processing of secondary resources, including grape pomace, containing a large amount of dietary fiber (DF), which are mainly concentrated in the cell wall of the pulp and skin of the grapes. Secondary raw materials obtained during the processing of grapes can serve as the basis for the production of new types of finished products with valuable and consumer properties of high biological value. Grape pomace has a rich chemical composition (they contain sugar in the form of fructose and glucose, pectin, organic acids, crude protein, fiber, calcium, phosphorus, polyphenolic compounds, vitamins). This article shows a study of the quality of grape pomace and powder obtained from dry raw material of drape pomace to reveal the possibility of grape powder using as an enriching component that will be a part of new types of finished products. As an objects of research, the pomace samples were taken after fermentation from red grapes and freshly squeezed white grape varieties from the 2017 harvest. The article describes the mechanical composition of dry raw materials, as well as the chemical composition of grape powder. The conclusion is made of the possibility of using a powder obtained from grape pomace as an enriching component with biological value in the composition of the new types of finished products.
