The total area of green spaces in the capital of Dagestan now stands at 3003.5 hectare, and in the mid-1960s - 186 hectares. Green areas of common use per capita in 2015 compared to 1960 has decreased dramatically and amounted to 3.6%, which is only 1.0% of the norm. The race of landscape construction of the city far behind the race of construction of residential and office sectors, and the existing green spaces either in quantity or quality does not matches the sanitary and aesthetic requirements, in addition there is a low level of artistic and architectural planning of green space. We have also described the questions of the history of the garden and the park building in Makhachkala and meticulously analyzed the rock-species (species, forms, varieties) of the composition of green space. We have marked the evaluation of their condition. Despite the great diversity of species composition (281 kind of woody plants, including 60 species of gymnosperms and angiosperms 221 views), we have noticed that almost everywhere there was cultivated only a small part of them. This is despite the fact, that the Republic of Dagestan has a rich species diversity of local flora, which can be effectively used in landscaping. Here, too, there are favorable climatic conditions for the introduction of new species. It should be noted that the private sector can be traced as having the opposite trend. Some recommendations have been given to improve the structure and condition of the trees and bushes planted in the city. Finally, we have shown the necessity of linking the production of green building works with the scientific activities of specialized education and research institutions in the city
In recent years leaf tan spot had dominated into
pathogenic complex of wheat in southern Russia. The
causative agent of this disease is hemibiotrophic
ascomycete Pyrenophora tritici-repentis (Died.)
Drechsler; imperfect state of Drechslera triticirepentis
(Died) Shoem. It causes two different
symptoms in susceptible wheat varieties: chlorosis and
necrosis. Under epiphytotic disease progression crop
losses can achieve 65%. One of the most important
elements of phytosanitary control of wheat cenosis is
scientifically relevant chemical fungicides application.
Biological efficiency of some fungicides against
Pyrenophora tritici-repentis has been estimated.
Research was conducted on the experimental ground
of FSBSI ARRIBPP on the variety susceptible to the
pathogen – Krasnodarskaya 99. Preparations were
tested one time at leaf-tube formation (Z37) phase or
two times: at leaf-tube formation (Z37) and start of
heading (Z51) stages. Double treatment was more
effective than a single one. Fungicides “Amistar extra”
and “Prozaro” have got the high biological efficiency
– 80,7 and 83,7%, consequently, and longer protective
period (up to 40 days) in comparison to every tested
fungicides
Some derivatives of 3-aminothieno[2,3-b]pyridines,
N-pyrazolo[3,4-b]pyridinil-3-carboxamides and
substituted naphthalene-2-sulfonic amides were
synthesized for the search of the new winter wheat
growth regulators. The growth regulating activity of
the new compounds was studied and the substances
with high growth stimulating effect were found
In the modern wine growing, for fighting against root
phylloxera an inoculation of European-Asian grapes
varieties on rootstocks steady against this wrecker is
used. In this article we present the information about
the types of rootstocks of domestic and foreign
breeding used in the modern branch of wine
growing. The area of their use is described; the
useful properties of rootstocks and their demerits are
highlighted. The purpose of this work is creating new
grapes rootstocks which wouldn't have the merits of
existing rootstocks. The short description of the
grapes rootstocks which were created in the Anapa
Zonal Experimental Station of wine growing and
winemaking such as AZOS-1, AZOS-2, AZOS-3,
AZOS-4, AZOS-5 and AZOS-6 is given in the
article. It is indicated that these rootstocks have a
high resistance to a leaf form of phylloxera, to
chlorosis and to some other diseases of a grapes
bush. They have the short period of vegetation, high
quantity of standard cutting from hectare and other
useful properties. In the article the description of a
new formation of rootstocks grapes bushes of "AOS-
1" and "AOS-2" with a free trail shoots is given. This
construction of grapes bush is developed by the
Anapa's Zonal Experimental Station of wine growing
and winemaking. We have also given all the
advantages of this forming in comparison with other
designs of grapes bushes. It is especially noted that
use of this forming of bushes increases the
productivity per men in the process of bushes scrap
and preparation of cutting; the expenditures on the
struggle against diseases and wreckers on the vineyards are reduced; the quantity standard of
grapes cutting increases by 27-33%
The article presents the results of the study to
determine changes in indicators of fertility in typical
Chernozem of the Belgorod region and the
productivity of winter wheat using different
agricultural technologies, including elements of
biologization
On the example of middle-aged and mature
valuable forest stands we have brought an
assessment of forestry and economic efficiency
of various options of silvicultural actions for the
reconstruction of invaluable young growths (17
objects with a total area of 102,6 hectares) which
was carried out in 1947-1959 and to formation of
plantings from subgrowth and young growth of
the coniferous breeds kept when carrying out
gradual and continuous cabins in 1962-1996 and
also from forest cultures (8 objects of 44,9
hectares) for conditions of the coniferous and
broad-leaved woods of the Republic of Tatarstan.
The results of the researches showed that the best
indicators of forestry and economic efficiency of
actions of care of the woods by reconstruction are
observed in pine plantings at a continuous way:
the grown-up wood reserves on a root (346-522
m3/hectare in 55 years) exceed stocks of modal
forest stands on 109-288 m3/hectare with
economic efficiency within 10625-50659
rub/hectare. Slightly less efficient - larch and
spruce plantings at a corridor way of
reconstruction. Similar indicators of actions for
formation of plantings from subgrowth represent
positive results as well: forestry efficiency made
from 31 to 208 m3/hectare, economic - within
10584-26846 rub/hectare. Based on the
researches we made conclusions, offers and
recommendations for practical use in forestry of
the Republic of Tatarstan
Many old varieties of grapes do not meet modern
requirements, so there is a need for improved
assortment of new high-quality varieties. The
translation of the vineyards of the black sea coast of
the Krasnodar region on inoculated culture is not fully
decided the fate of the viticulture of the area. Weak
resistance of American rootstocks to increased content
of calcium and salts in the soil, caused the weakening
of the bushes, reducing the vigor of the shoots, their
maturation and yield of grape plantations in some
areas of the district while reducing their quality
indicators. In this regard, the development of new
high-yielding varieties suitable for own-rooted
viticulture remains the most urgent task for breeders.
The article shows the potential of many years of
breeding work and study of grapes of technical
varieties in Anapa Zone Station, tolerant to phylloxera
and resistant to fungal diseases and frost, with high
quality products and gives a brief description of some
prominent grape varieties
Small-leaved lime (Tília cordata) is wonderful species
of trees, producing honey. This tree species is not
cultivated in forest tree nurseries of Head forestry
department of the Omsk region for the purpose of an
artificial reproduction. Small-leaved lime grows wild in
Bolshyi Uki, Ust-Ishym and Tevris areas. This forest is
the basis for a honey production. Small-leaved lime
occupies a very small area, which equals 1,5 ha. Natural
reproduction of small-leaved lime in the Omsk
Pryirtysh district is a reliquiae. Questions of
reproduction of small-leaved lime have not been studied
yet. Shoots cloning of small-leaved lime has an
important practical value for areas of natural
reproduction. A technology of seed reproduction has
not been developed for the Omsk region. Complexity of
the matter is in the existence of a long and deep
physiological quiescent period of small-leaved lime
seeds. Experimental facts of small-leaved lime seed
reproduction has been described in this article. Results
of measuring of height and root neck diameter of oneand
two-year old plants have been shown. The
influence of putting young plants in the shadow on
their growth and development has been evaluated. It has
been shown that seedlings received from small-leaved
lime growing in the Оmsk State Agrarian University
Dendrology Park have large variation in the growth
and development parameters and the fact of casting
shadows on the plants truly affects the height of oneand
same as two-year old samples
Grapes are product of areas. Grape plant is very plastic
and can grow on almost all types of soils except highly
saline, fusion and wetlands. In studies of many
authors, it was indicated the influence of different soil
types and their properties on the growth of the vine
plants, the quality of berries and their products. The
object of study is soils and vines growing on them,
laws and processes affecting the formation of grape
production. Research methods are expeditions, field
and laboratory. The article presents data on the effect
of agrochemical soil properties (pH, solid residue, the
amount of aqueous extract ions, chlorine ions,
alkalinity (НSO3¯), calcium ion, magnesium ion, total
carbonate, active carbonates, nitrate nitrogen, mobile
phosphorus, exchangeable potassium , humus, humus
reserves) on the formation of the harvest of grapes and
wine products (tasting score, the extract, the amount of
phenolic compounds, the amount of organic acids, the
amount of amino acids, metal ions, potassium ions,
sodium metal, magnesium ions, calcium ions, the
amount of metal ions). With the help of statistical data,
we can establish the effect of weather conditions on the formation of 2009-2011 qualitative wines of
Cabernet Sauvignon
