The technology production of microbiology preparation for protecting of plants from ill and insects was presented in this article. There are measures for improving the nutrient medium for growth of microorganisms
The features of seeding and vegetative reproduction of
Hibiscus Syrian (Hibiscus syriacus L.) in the South
regions of Russia are accounted in the article. It is
shown that the not sorted Hibiscuses reproduce better
by seeds. Sowing is made before winter (November).
The young growth appears on April-May of next year.
The seedlings of first-year are wintering badly in the
open soil; therefore, it is better to keep them in the
basements in sand. When one-year seedlings are
planting next spring we receive the standard seedling
in the autumn this year. Planting material of high
quality of Hibiscus Syrian was grown by means of
inoculation and by the grafting method. It is
recommended to execute an inoculation in the first tenday
period of September. It is possible to execute the
reproduction by means of inoculation in case of deficit
of shoots of high quality plants and for the rapid fixing
of sort. It is preferable to reproduce a Hibiscus Syrian
by wood shoots in the frames or by green shoots in the
unheated greenhouses in an autumn-winter period. The
best results in the carried out research were got at
planting shoots for further growth in the containers at
the greenhouses with creating of shadow in a summer
period. The high speed of shoots growth in the
containers of cv. Duc de Brabant, cv. Woodbrige and
cv. Russian Violet varieties are observed. The
vegetative mass of shoots of cv. Speciosus,
cv.Carneus Plenus and cv. Red Heart varieties
increases more slowly. A conclusion follows, that the
studied crop must take the deserving place in the
assortment of decorative bushes of plant nursery farms
The changing dynamics of nutrients in soil, doses of mineral fertilizers, efficiency, a mode of onion irrigation on irrigated soils of Rostov region are resulted in the article
The article reviews four variants of laying nurseries of
primary branches of seed production of long-grained
rice varieties of the Kuban breeding taking into
account their biological features, plots area ranges
from 0,7 m2
to 1,1 m2
, seeding rate for one family –
from 100 pcs./m 2 to 170 pcs./m2 . We have studied
traits of long-grained rice varieties of the Kuban
breeding - Ivushka, Avstral, Kurazh, affecting the
yield and quality of seeds: yield, multiplication factor
and fractional composition of seeds depending on
laying multiplication nursery of first year progeny.
The differences between varieties by the type of
tillering, vigor, germination of seeds depending on
planting system are shown. Optimal way for laying
seed nurseries is found: for long-grained varieties with
medium tillering (Kurazh type) – row length – 3,3 m
and seeding rate – 120 caryopses/m2
; for those with
intensive tillering (Ivushka type) – row length – 3,8 m
and seeding rate - 120 caryopses/m2
. This will allow
using mechanical method of sowing using selective
cassette seeding-machine in the primary seed
production, reducing cost of seed production and
increasing efficiency of labor, increasing volume of
seed production of long-grained rice varieties in short
terms and accelerating their implementation in the
Kuban region for import substitution
The article shows the parameters of growth of main tree species depending on planting density, placement of plants, location in the profile of plantations, the effectiveness of plantations
This article surveys the results of studies of the process of differentiation of inflorescences of wintering buds of grapes of different varieties in the period of relative dormancy in the conditions of Taman
The article presents data on the formation of the embryonic fruitfulness of central buds of wintering buds grapes of different origins in the period of relative calm of grapes and early spring period in dynamics with presence of positive air and soil temperatures
The article presents the data of the effect of sowing date, biologics and fertilizers on parameters of photosynthetic activity and symbiotic crops, yield and technological properties of lentil seeds. The calculation of the specific activity of the symbiosis (UAS) for the largest consumption of nitrogen by plants and lentils active symbiotic potential (TSA) crops of lentils, collection of protein per unit area under foothill zone of Kabardino-Balkaria
This article is devoted to studying the influence of
conditions of keeping and feedings on broilers of Hubbard
RedBro cross, and the quality of the received
products in case of application of floor and cellular
content in the conditions of a farm. It was found that
when receiving a feed of its own production with the
use of feed ingredients grown in farms without pesticides,
recorded a statistically significant reduction in
the potentially dangerous health animal substances. As
compared with a factory forage therein reduced pesticide
content by 14 times, mercury and arsenic is 24
times, 5 times cadmium, lead 10 times. Results of
studying of economic indicators of cultivation of
broilers of cross Hubbard RedBro and also chemical
composition and quality of carcasses demonstrated that
the essential difference between a floor and cellular
condition of keeping is not established, however use of
a diet on the basis of what forages promoted statistically
reliable decrease in concentration of toxic metals in
muscles of a bird of experienced groups. As a result it
was found that use of the researched compound feed in
diets of broilers raised indicators of biosafety and provided
ecologically safe (“organic”) meat products of
poultry farming
In the article we have given the complex estimation of the productive and meat quality of genuine Russian pigs of meat types, and crossbred animals received with participation of foreign varieties
