Тhe results of the evaluation of the condition of trees
and shrubs in various types of park and garden stands
located on the territory of several educational buildings
of Petrozavodsk state university are presented in the
article. The details of the planning of sites and the
spatial location of trees and shrubs are displayed. The
species composition and the distribution of plants
according to the categories of viability are identified.
The 3D computer models of the studied territories with
inventory results are created. The analysis of the
plantation allows us to offer projects on formation of
the landscape planning structure of the university
campus of PetrSU
The article has considered the influence of modern
climate changes on the intensity of erosion processes
within the boundaries of the basic landscapes of the
region. It has given the results of the spatial
distribution of the rainfalls. The most noticeable
climate changes of the Bryansk region are reflected in
the decrease in the activity of erosion during snowmelt
due to the lower amounts of snow and soil frost depth.
In the area, the dynamics of rainfall does not detect a
single trend. The processes of erosion and deflation are
studied in the relationship, the manifestation of these
processes on the territory of the Bryansk region. It has
published the results of the risk analysis of erosion and
deflation on forest soils of the region and justified the
application of G. V. Bastrakov’s method for
modeling erosion-resistant agricultural landscapes.
This approach has a number of advantages over the
other known methods. In our case, regardless of soil
and climatic and geomorphological conditions, the
challenge is to ensure such events in which erosion
resistance of the land will not be below a critical value.
The research results are the initial data in designing
soil conservation activities on the territory of the
Bryansk region. The obtained data of the erosive
properties of soils from climatic changes enable the
study and forecasting of the development of
agricultural landscapes of the region in the medium
term
The article contains information about landscape architecture analysis of the cities, its methodology and an example of using of this approach on the part of the Red Line touristic rote in Yekaterinburg. Analysis process included counting of ratio of built-up areas, landscaping and roads, and examination of the street transvers profile with further filling of local landscape passports. As the object of study, the part of route between the opera and ballet theatre and the monument of V. Vysotsky and M. Vlady. Here is noticeable contrast between environmental characteristics of stopping point areas. The site around the theatre has enough quantity of landscaping, good compositional solution, well developed path network. The intermediate part of the route passing by Krasnoarmeyskaya st. has asymmetric shape of the transvers profile. The street landscaped on East side but public services on the opposite side not improved – homogeneous facade creates adverse visual field here. A sidewalk on the East part of the street duplicated with a path in a garden. Analyzed zone around the second point has no single composition, high traffic influence level. Landscaping almost not presented here, varied advertising constructions widely installed. For improve environment, developed a list of recommendations. It contain using of container plants to separate pedestrian area; reconstruction of the East part of Krasnoarmeyskaya st. with replace sidewalk for green hedge; repair or replacement of sidewalk asphalt pavement on the West side of the street; reconstruction of area near the Antey business-center with creating greened dividing line
The purpose of this research is to assess the ability of
reclamation plantations of walnut and black nut to accumulate heavy metals in phytomass – leaves, shoots, fruits. The studies were conducted in the Rostov region, as well as in the Krasnodar and the Stavropol regions
The purpose of the research is to assess the ability of reclamation plantations of walnut and black nut on the accumulation of heavy metals in their phytomass – leaves, shoots, and fruit. The studies were conducted in the Rostov region, the Krasnodar and the Stavropol regions. In the samples of vegetative aboveground and soil (under the canopy nuts) we have defined qualitative content of total forms of heavy metals of Cu, Ni, Co, Zn, Mn, Pb, Cd, Cr. This ability is the accumulation of heavy metals in leaves, shoots and fruit that fall from the atmosphere. Later, the bulk forms of these metals with the annual litter come to litter, and then – into the soil
The article deals with the problem of overgrowing of ponds and reservoirs. One way to reduce the intensity of development of plants is covering the territory with geosynthetic materials. Laboratory researches of geosynthetic materials are carried out. The optimum size of the layer of soil, which is loading geotextiles, was determined
Kormilitsa Lisa grape was created in Greece by P. Zamanidi and L.Troshin in 2003 with crossing the varieties of the Pervenets Maharach with varieties of Muscat white. The duration of the production period is 146-155 days. The yield is high. The average mass of clusters of 250 g. It has winter hardiness, drought-resistance and high resistance to fungal diseases in comparison with varieties of Vitis vinifera; it is also tolerant to phylloxeras. The flower is ambisexual. The bunch is average, cylinder-conic, medium density. The berry is average, oval, green-yellow colour, with a thick wax coating. The skin is thin, thick, and strong. The pulp and juice with a strong Muscat flavor. Sugar content is high with acidity constant. When overripen, it dries long and is stored on the bushes. The variety is meant for manufacture of dry white wine of superior class and high-quality dessert and sweet wines; It is also suitable for the development of high-quality juices and compotes
In this article, the orderliness of the wheat plants phytomass increase has shown, observed until plants growth stopping time, which concurs with flowering ending. The discovered orderliness determinates the nitrogen, phosphorus and potassium (N, P, K) transfer dynamics. The mathematical model of N,P,K elements carrying out from roots - inhabited soil layer has been proposed
The process of the presowing seed treatment with
alternating electromagnet field of the commercial
frequency (EMF CF) 50 Hz is economically
efficient. The use of the EMF CF 50 Hz in the unit
with ring pole pieces allows increasing the
germinating energy and power. The electromagnet
seed treatment in the units with ring pole pieces is
the perspective process of the presowing treatment
which does not make unhealthy influence on the
operating personnel. At the presowing treatment one
has to take into account three factors; they are the
arrangement of seeds in the working chamber, the
time of treatment and the seed humidity. In this
article the authors recommend to promote the unit
consisting of a magnetic circuit with ring pole
pieces of the rectangular cross-section, a
magnetizing coil and an embedding of the nonmagnetic
material in the working chamber which
allows to increase the germinating energy of spring
barley by 10% and the germination by 6,5%. The
addition to crop capacity has run to 7% as a result of
the spring barley treatment. We analyzed the
parameters of the working chamber of the
alternating electromagnetic field source of industrial
frequency of 50 Hz, we established the dependence
of the rate of treatment on the parameters and
modes of installation, which are confirmed by
laboratory tests. Long-term field studies revealed
that the field germination rate of the seeds of spring
barley treated with EMF IF, even under adverse
weather conditions, exceeds by more than 8% of the field germination rate of control samples
According to the results of long-term evaluation of promising hybrids of lavender angustifolia the ability to predict the influence of abiotic factors on the yield and gathering of essential oil of inflorescences is shown. Correlations, agronomic stability and variability of the yield of hybrids are defined
