The purpose of the study was to examine a century of
experience of growing of forest cultures of the
Siberian stone pine in forest conditions in the region of
the Middle Volga. To achieve these objectives, we
have investigated old growth culture of Siberian stone
pine in the conditions of fresh oak forests in the
territory of Rootka forestry of the Mari El Republic.
Culture of Siberian stone pine was planted after
continuous tillage. The distance between rows was 2,5
m, step landing – 1,0 m. The site was divided into five
options, depending on variations in the width of
planting strip (I-48 m, II-44 m, in III-40 m, IV - 36 m,
V - 32 m). The studies have shown that the Siberian
stone pine trees, regardless of the variant, are
characterized by good clean ability from twigs, which increases with decreasing of the width of the curtain. It
can be noted that in the 100-year-old age, the average
height of trees reaches of 28,7 m, an average diameter
of 49,8 cm. Stock of forest reaches 795,3 m3
/ha. Best
annual increase is observed in growing cultures of
cedar in the wings with a width of 40 m and is 7,95-of
7,93 m3
/ha. Based оn the research, we have concluded
that Siberian stone pine should be recommended for
introduction into the zone of coniferous-broadleaved
forests of the Middle Volga region. When creating
crops, it is necessary to use larger seedlings and plant
density is not more than 1,0 thousand pieces/ha, and
the width of the planting strip shall be not less than
40,0 m.
Limited resource of irrigation water in the South of
Russia is a particularly actual task in the production
of moisture-loving crops, such as rice. To solve the
problem of rational use of water when watering is not
possible without the organization of an automated
water distribution. As it was shown by the analysis of
tools and technologies of regulation of water supply,
the most promising, form tested and used, can be tape
regulators of flow and water level. They have a
simple construction diagram, unpretentious in
operation. However, we have identified a fault –
unregulated leaking, not fully covered through the
bore, which in turn increases the uncontrolled
consumption of irrigation water. To solve this
problem we propose a number of designs, protected
by patents of the Russian Federation, having special
fixture to ensure unauthorized leaks, even in a state
almost close to the fully closed opening expiration
from the regulator. The article comprehensively
considers hydraulic studies of controller initially,
without any additions that contribute to the problem
of eliminating leakage. The proposed study with the
analysis of the distribution of velocities and pressures
in the design of belt regulator, will allow you to have
the basic reference model against which it will be
possible to analyze the degree of influence of
constructive-technological changes at the work the
newly developed devices. For this, we modeled tape
controller in the software package FreeCАD version
0.15, when using SAE - system FlowVision. The task
of modeling water flow were solved in flat statement,
including the moment of full closing of the belt
passage opening of the regulator. For plotting surfaces, lines, levels and cross-section response
functions, we used a software package wxMaxima.
The results obtained allowed a comprehensive
analysis of the work tape of the locking device,
hydraulically actuated device in all modes of the
major factors and, in the future, will help to address
the issue of studying the impact of introduced
technological changes in the design of controllers
Currently, due to the risk of global warming because
of increased concentrations of greenhouse gases in the
atmosphere, carbon-deposit function of forest
ecosystems, thanks to which stabilization of gas
composition of the atmosphere takes place, has great
importance [1]. Forest is one of the main components
of the biosphere. Forests protect soil from erosion,
provide stability hydrological regime of rivers, supply
atmosphere with oxygen, biologically active
substances, purify of harmful impurities, create
optimal environmental conditions and play an
important environmental role. However, because of
intensive anthropogenic influence (unregulated
logging, technogenic environmental pollution
recreation) forest ecosystems are experiencing stresses
at which irreversible processes of degradation of
communities of economically valuable main forestforming
species of both natural and artificial origin
take place [6]. Evaluating carbon-deposit function of
forest plantations, CO2 emissions to the atmosphere
through the soil respiration must be taken into account,
which can vary within wide limits. Productivity of
forests is largely driven by carbon dioxide, released
from the soil. Soil carbon dioxide provides demand of
forest plants for photosynthesis. With increasing
intensity of soil respiration, positive balance is
maintained [2]. Based on the method of V.I. Tarankov
for evaluation of carbon-deposit and oxygen-producing
functions of wood cenoses [2], similar research is
carried out in RSI "Kuban forestry", the KarachayCherkessia
Republic
The article gives the results of the three years of
research to identify the main species composition of
fungal pathogens when stratified open and closed
methods. Biological efficiency of Guapsin, 0,2%, and
Trichodermin, 0,5% is shown. During the period of
stratification, using an open method "on the water", the
following pathogens have evolved: Cladosporium
herbarum (18,6%), Trichotecium roseum (16,3%),
Phomopsis viticola (13,9%), Alternaria spp. (13,4%),
Penicillium sp. ( 9,1%), Aspergillus sp. (5,6%),
Pythium sp. (4,3%), Gonatobotrys flava (4,3%),
Mycelia sterilia (2,8%), Botrytis cinerea (2,2%). The
studies found that the close method of stratification in
the peat developed the following specific composition
of pathogens: Penicillium spp. (21,1%), Phomopsis
viticola (16,4%), Botrytis cinerea (15,3%),
Trichotecium roseum (11,1%), Alternaria spp. (8,2%),
Mycelia sterilia (1,0%). During the period of
stratification, biological efficiency Guapsin, 0.2%, and
Trichodermin, 0,5%, was 31,9-88,0% and 28,2-86,3%,
respectively
This article presents results of trials of feed additives
called "Yoddar-Zn" and "Glimalask-Vet" to improve
quality characteristic of meat of beef cattle. It was
established that the most efficiency of these additives
was achieved when used in complex. The carcasses of
calves, which were consuming a complex of additives
"Yoddar-Zn” and “Glimalask-Vet” (I c.), contained
meat of the highest sort more than control by 6.48 kg,
the animals which consumed only "Yoddar-Zn” (II c.)
- 3.50 kg, the first-sort - at 15.19 and 7.86 kg. In
experimental groups of calves there were observed
more intense integral characteristics of meat color. The
flesh of carcasses from the calves of experimental
groups, the fat was higher than control, 0.13 and
0.07%, protein - by 1.79 and 0.97%. Animals
experimental groups synthesized more protein at 5.45
kg, or 13.70%, and 2.62 kg, or 6.59%, energy - to
304.3 MJ, or 18.17%, and 146.8 MJ, or 8.77%. Meat
of experimental animals, contained more essential
amino acids. Protein meat quality indicator was higher
than control, 0.73 and 0.28, amino acid index - by 0.17
and 0.04. The meat from calves of experimental group
had a higher culinary and technological parameters,
optimal fractional composition of muscle protein and
lipid composition of adipose tissue, better digestibility
We have proposed the method of presowing processing of
seeds of winter wheat using a hydrophobic paraffin-wax
system of the new composition. Water protected paraffinceresin
coating has been used before for storage of garlic.
However, the paraffin coating were not applied to wheat
seeds and were not investigated their effect on
germination, growth and further development of plants of
winter wheat. This work has been done for the first time.
The ceresin wax is replaced by sunflower wax. New
component composition of the hydrophobic waterproof
coating winter wheat seeds: sunflower wax – 15-20 % wt
.; paraffin – all the rest of it. Sunflower wax is a surfaceactive
substance and has the properties of the plasticizer
and the dispersant of the dispersed structure of the
paraffin. The advantages of this coating: it protects the
seeds from moisture loss, regulates the timing of their
germination, contributes to the preservation of
accumulated nutrients, and enhances plant growth and
development; it increases the yield of wheat. In the field,
we have set growth stimulating ability of paraffin-wax
coating of winter wheat seeds of variety called Charade.
The resulting increase in yield was 20% (control of 52.6 с
/ ha), while maintaining the quality of grain. This use of
sunflower wax solves an important environmental
problem – disposal of oilseed production waste
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
A fundamental element of the technology is the use
of beef cattle in the economic purposes of biological
resources of animals. In the development of modern
technologies there is a lack of focusing on one of the
main features of cattle – its own perception of the
environment, that is panoramic (binocular) vision. In
the modern cattle breeding we focuse on the
development of a variety of exterior signs. However,
one of the indicators that affect the behavioral
responses of animals (the degree of development of
the muzzle and the forehead of the animal, the shape
of the head) does not have due importance. The
author has conducted its degree of development
studies in bulls and cows of different breeds. Along
the length of the head, meat breeds (Hereford,
Aberdeen Angus, Simmental, Charolais) gave way to
Red Steppe 14.9; 15.5; 5.5 and 5.0 cm (27,5; 28,6;
10,1 and 9,2%, P
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
Searching for new promising plant growth regulators
and antidotes, we have synthesized a series of Nsubstituted
naphthalene-2-sulfonylamides. Synthesized
compounds have been studied as potential growth
regulators of economically significant crops - winter
wheat, sugar beet, sunflower, soybean, and herbicide
antidotes for sunflower growing plants. The substances
with high growth stimulating and antidote effect were
found
