В статье проведен инвентаризация прудов, копаней и мини-водохранилищ, расположенных на территории Волгоградской области. В Волгоградском регионе находятся порядка 5000 искусственных водоёмов различного назначения. Не смотря на такое количество водных объектов район исследования относится к территориям с недостаточным количеством водных ресурсов, что обусловлено природной зоной сухих степей и полупустынь и резко континентальным климатом. Мониторинг большинства прудов и копаней не проводится, научно-методические работы, посвященные данной тематике, почти отсутствуют. С целью выяснения современного состояния искусственных водных объектов области были проведены полевые выезды для их визуального осмотра и мониторинга, а также исследованы морфометрические, физические и статистические данные, предоставленные администрациями районов и поселений. В климатических условиях эти водные объекты играют важное значение: орошение сельскохозяйственных угодий, обводнение прилегающих территорий, разведение рыбы, водоплавающей птицы, хранение воды для различных хозяйственно-бытовых нужд, судоходства, противопожарных и противоэрозионных целей и т. д. Многие гидротехнические сооружения, расположенные на искусственных водоёмах, находятся кризисном состоянии: плотины на некоторых разрушены или прибывают в нерабочем состоянии, а вода в них отсутствует. Состояние некоторых прудов в регионе оценивается как предкризисное и кризисное. На многих из них встречаются таблички на запрет некоторых форм мобильной и стационарной рекреации: вылова рыба, пляжной рекреации, водный туризм и др. The article contains an inventory of ponds, pits for collecting water, and mini-water storages located in Volgograd Oblast. In Volgograd Oblast, there are about 5,000 artificial reservoirs for various purposes. Despite such a number of water bodies, the study area belongs to territories with an insufficient amount of water resources, which is due to the natural zone of dry steppes and semi-deserts and a sharply continental climate. Most of the ponds and pits for collecting water are not monitored, and there are almost no scientific and methodological works devoted to this topic. In order to clarify the current state of artificial water bodies in the region, field trips were carried out for their visual inspection and monitoring, as well as morphometric, physical and statistical data provided by the administrations of districts and settlements were studied. In climatic conditions, these water bodies play an important role: irrigation of agricultural land, watering of adjacent territories, fish and waterfowl farming, storage of water for various household needs, shipping, fire-fighting and anti-erosion purposes, etc. Many hydraulic structures located on artificial reservoirs are in a state of crisis: dams on some of them are destroyed or are inoperative, and there is no water in them. The condition of some ponds in the region is assessed as pre-crisis and crisis. On many of them, there are signs prohibiting some forms of mobile and stationary recreation: fishing, beach recreation, water tourism, etc.

Aim. The main aim of the research is to study the conditions of existence and the timing of the development of the preimaginal and imaginal phases of blood-sucking mosquitoes, depending on the natural and climatic conditions. Methods. Adult species were collected at the roost sites and at the time of swarming with the use of scoop net every five days throughout the season. The larval phases of bloodsucking mosquitoes were taken into account in all given reservoirs of various types using a photocell. Discussion. The results of the study showed that in the study area, the largest region where mosquitoes are reproduced is mainly artificial reservoirs accounting for approximately 65%, natural water bodies (25%) and hollows of tree trunks (10%). The saturation of the larvae of the malarial mosquito of the genus Anopheles was 82 species/m2, non malaria mosquitoes of the genus Culex – 234 species/m2, while Aedes genus made up 105 species/m2. Conclusion. There are 19 species of mosquitoes inhabiting Dagestan. The development of preimaginal and imaginal phases of blood-sucking mosquitoes on the territory of Dagestan is ecologically diverse.

Water Quality Classification

The study aimed to define the classes in the Heavy Metals Section of the Regional Environmental Ranking System based on long-term data (1997-2017). When distinguishing water quality classes, the following factors were taken into account: background content of heavy metals, content of heavy metals in water bodies exposed to different levels and character of anthropogenic pollution, and response of biological communities to toxic pollution of their natural habitats. According to the proposed classification, the non-contaminated water of Сlass 1 contains the following: Cd<0.2, Cu<2.5, Zn<4, Pb<3, Cr<0.5, and Ni<0.5 μg dm-3. Class 2 water is characterized by Cd<0.5, Cu<6, Zn<6, Pb<7, Cr<1, and Ni<2 μg dm-3 content. Moderately polluted water of Class 3 contains Cd<3, Cu<10, Cr<10, Ni<10, Zn<20, and Pb<20 μg dm-3. Concentrations of all heavy metals increase proportionally and exceed 30-100 μg dm-3 in the most polluted water of Class 6. The proposed methodological approach assesses not only the local content of heavy metals in water bodies of Kazakhstan but also the degree of toxic pollution of their vast catchment basins. The proposed methods are applicable to other arid regions with similar physical and climatic conditions.

World Industry

At the present stage of development, the entire world industry has faced the problem of rational use of renewable natural resources, in particular the most efficient ways of wastewater treatment and the use of accumulated waste in the production process as a secondary raw material. In particular, the alcohol industry, as one of the components of food, medical, chemical and various industries,leads to the formation of huge amounts of waste, including wastewater. The food industry, like any other industry, has a negative impact on the environment. Water bodies are the most affected by the food industry. Almost the first place in terms of water consumption per unit of production is the production of alcohol. Consumption of large amounts of water leads to the formation of wastewater, which is highly polluted and adversely affects the environment. Due to the high chemical and biological consumption of oxygen, specific color and odor, suspended solids, low pH value, the purification of such waste in the filtration fields and discharge into water bodies is not possible. The purpose of our work is: 1) conducting the analysis of the alcohol industry potential in Ukraine in recent years, and methods of waste disposal as a potential source for the development of bioenergy. 2) environmental aspects of the alcohol industry modernization at present stage of development and implementation of modern wastewater treatment technologies.

Вертикальное озеленение с участием различных видов лиан в современных условиях имеет важное эстетическое и санитарно-гигиеническое значение. Особо актуально решение вопросов обогащения флоры городских территорий лианами в степных районах в связи с бедным видовым составом и резким ухудшением экологической ситуации. Объектами исследований являлись 7 видов лиан, различных жизненных форм (однолетние, многолетние), произрастающие в населенных пунктах Саратовской области (Аткарск, Саратов). Цель исследований – изучение эколого-биологических особенностей и мелиоративных свойств лиан и выявление перспектив их использования в вертикальном озеленении селитебных территорий Саратовской области. В ходе исследования видового состава, были выявлены наиболее популярные виды однолетних лиан: ипомея красно-голубая (Ipomea tricolor (L.) Roth) и ипомея пурпурная (Ipomea purpurea (L.) Roth), горошек душистый (Lathyrus edoratus L.), настурция (Tropacolum peregrinum L.) и фасоль огненно-красная (Phaseolus coccineus). Большинство (70%) из них произрастают в местах ограниченного пользования. Изученные виды лиан в исследуемых регионах достигают средних природных показателей (при наличии надлежащего ухода), обладают хорошими показателями жизненного состояния, обильно цветут и плодоносят. При воздействии токсикантами различной концентрации на листовые пластинки лиан установлено их степень устойчивости. Выявлено, что однолетние лианы лучше использовать в декоративных целях, а не в санитарно-гигиенических. Сравнительная оценка однолетних видов с многолетними лианами (девичий виноград пятилисточковый и клематис тангутский) показывает устойчивость многолетних видов (в среднем на 3 балла - 40%). Разработаны варианты декоративных композиций с участием травянистых лиан. По степени декоративности выделены однолетние лианы – Ipomea tricolor, I. purpurea (37 – 41 балл), средней степенью отличаются – Lathyrus edoratus (33 балла), Tropacolum peregrinum (30 баллов) и Phaseolus coccineus (20 – 27 баллов). Преимущество многолетних лиан заключается в их устойчивости к резким изменениям климатических условий (на 40 %) по сравнению с однолетними формами. Поэтому они более предпочтительны для озеленения городской среды. Для усиления декоративного эффекта в сезонном аспекте рекомендуются сочетать расширение видового и формового разнообразия растений (многолетние и однолетние лианы, древесно-кустарниковая, цветочная растительность). Установлено, что природно-климатические условия зоны степи и лесостепи в пределах Саратовской области являются достаточно благоприятными для нормального роста и развития древесно-кустарниковой растительности, в том числе травянистых лиан. Таким образом, обоснованное применение древесных лиан в комплексе с традиционными видами насаждений позволит создать комфортные условия проживания населения, регулировать оптимальный температурный баланс и создавать благоприятные микроклиматические условия. Vertical gardening with different types of vines in modern conditions is important aesthetic and sanitary-hygienic value. It is especially important to address the issues of enrichment of the flora of urban areas with vines in the steppe regions due to poor species composition and a sharp deterioration of the ecological situation. The objects of research were 7 species of lianas, various life forms (annual, perennial), growing in the settlements of the Saratov region (Atkarsk, Saratov). The aim of the research is to study the ecological and biological features and reclamation properties of vines and identify the prospects for their use in vertical gardening residential areas of the Saratov region. In the study, species composition was the most popular species of annual vines: morning glory red-blue (Ipomea tricolor (L.) Roth) and purple morning glory (Ipomea purpurea (L.) Roth), the fragrant pea (Lathyrus edoratus L.), nasturtium (Tropacolum peregrinum L.) and runner beans (Phaseolus coccineus). Most (70%) of them grow in restricted areas. Studied species of vines in the study regions reach average natural performance (with proper care), have good indicators of vital condition, bloom abundantly and bear fruit. When exposed to toxicants of different concentrations on the leaf blades of vines established their degree of stability. It was revealed that the annual vines are better used for decorative purposes, and not in the sanitary-hygienic. A comparative assessment of annual species with perennial vines (maiden grapes and clematis Tangut) shows the stability of perennial species (an average of 3 points-40%). The options and decorative compositions with the participation of herbaceous vines. According to the degree of decoration of the allocated annual vine – Ipomea tricolor, I. purpurea (37 – 41 points), the average degree of differ – Lathyrus edoratus (33 points), Tropacolum peregrinum (30 points) and Phaseolus coccineus (20 to 27 points). The advantage of perennial vines is their resistance to sudden changes in climatic conditions (40 %) compared to annual forms. Therefore, they are more preferable for greening the urban environment. To enhance the decorative effect in the seasonal aspect, it is recommended to combine the expansion of species and form diversity of plants (perennial and annual lianas, tree and shrub, floral vegetation). It is established that the climatic conditions of the steppe and forest-steppe zone within the Saratov region are quite favorable for the normal growth and development of tree and shrub vegetation, including herbaceous lianas. Thus, the reasonable use of wood vines in combination with traditional types of plantings will create comfortable living conditions for the population, regulate the optimal temperature balance and create favorable microclimatic conditions.

The article notes that the growing popularity of healthy lifestyles contributes to the increase in consumption of fruits and berries. At the same time, the analysis of the dynamics of the gardening industry for 2000-2018 shows that the problem of providing fresh fruits and berries to the population remains one of the most important. Based on actual data, linear and logarithmic models of time series of key industry indicators for the period 2010 – 2019 have been compiled. Calculations showed that in the Russian Federation as a whole the trend of reduction of sown areas of perennial fruit plantations will continue with growth of yield and gross fees. In this regard, the issues of distribution and introduction of gardens of intensive type are updated. An overview of the views of domestic scientists-gardeners on the concept of “intensive garden” is given. It has been established that the distribution of intensive gardens is possible only if there are favorable natural and climatic conditions and a developed scientific and production base of nursery management. The current state and problems of gardening in one of the leading regions – the Republic of Dagestan - are considered. A significant technological lag of region in the further development of intensive horticulture has been identified. Various directions of intensification process in horticulture as the main and necessary condition of growth of efficient and sustainable production are summarized.

The results of research on the current state of the nitrogen fund (reserve regime) the Kizlyar pastures. It was found that the total nitrogen ranges from 0.15-0.2 %, nitrogen easily hydrolyzed from 2.4-5.3 mg/100g in light-chestnut, meadow-chestnut soils and saline typical, and has a medium and low degree of security. The humus horizon is more enriched with nitrogen on soils of meadow-chestnut and light-chestnut compared to typical saline. N and C reserves in the soil in spring are 5.0 and 13.4 t/ha, respectively, and in autumn N and C reserves are 1.5 times lower, due to decrease the number of species and projected coverage up to 40-50% of phytocenoses in autumn, and also depends on the climatic conditions of the annual seasonality. In the control area with intensive grazing, nitrogen and carbon reserves in the soil are 1.6-1.8 times lower.
