Results of researches of influence of anthropogenic factors on the condition of tree plantations in Maykop
The article presents the results of studies on the influence of the conditions of the foothill horticultural zone of the Krasnodar region and the crown shape on the agrobiological characteristics of the growth and fruiting of apple trees of the Idared and Renet Simirenko varieties. The objects of the study are Idared and Rennet Simirenko, trees of winter apple varieties, grafted on MM 106 rootstock. Trees were planted according to the 5 × 3 m scheme; crown width 2.0 ... 2.5 m. Orientation of rows from east to west. The garden is located on the northern slope with a slope of 3 degrees. The scheme of experience: option 1 - sparse-tiered crown (control); option 2 - flattened crown. In the experiment there were 2 options, in each option 10 typical trees were taken. Repetition: tree - plot. The location of the experiment is the Abinsky district of the Krasnodar region. Agricultural records of growth and fruiting of apple trees were carried out according to generally accepted methods, statistical processing of research results was performed by the method of variance analysis described by B. Dospekhov. The results of our studies showed that when flattening crowns, the variety Idared increases the average weight of apples by 22.9%, the yield of fruits of the highest and first grade by 43.6%, the intensity of integumentary coloring of fruits in the peripheral zones increases by 1.44, and in the center crowns 2.7 times, compared with sparse-tier crowns. In the variety Renet Simirenko, the fruit weight increases by 8.9%, the yield of the highest and first grade fruits by 14.6%, the number of fruits with color by 18.7%. Thus, in apple orchards with a 7 x 4 m planting pattern (on MM106 stock) under the conditions of the foothill horticultural zone of the Krasnodar region, flattened tree crowns should be formed for the Aydared variety (aged 14-15 years), which significantly improves the quality of the products
The article presents results of the study on the use of
associations of probiotic bacteria in black-and-white
breed calves. We have analyzed the effect of
associations of probiotic bacteria on hematological
(red blood cells and white blood cells, hemoglobin and
hematocrit) and blood biochemical parameters at
calves. It was found that the associations of strains of
Bifidobacterium bifidum DSM 20456, ATCC 29521,
and Enterococcus faecalis H22; Bifidobacterium
bifidum DSM 20456, ATCC 29521 and Enterococcus
faecium UDC 86 do not have significant changes in
the basic blood parameters of the animals, while
improving some of counts during their use
In the article we have studied the influence of breeding Stavropol Rams breed and Australian meat merino for increase a wool productivity at offspring received from crossing with Soviet merino females
In the article, the analysis of the influence of the troubles of the suspension elements on the break dynamics of the car, equipped with the regulator of the break powers is represented. It is offered to control the remaining inflexibility of the tail springs when diagnosing the brake system
This article studies technologies of cold pressing in flax seeds of low-linolenic and ordinary sorts. We studied how conditions of flux seeds pressing influence acid and peroxide values of oil as well as fraction of total mass in oilcake. The results of experiment have been mathematically processed
The article shows the results of two years of research of the impact of various technologies of cultivation of winter wheat with alfalfa predecessor
In this article, we review the influence of different production technologies for nitrogen, phosphorus and potassium in the soil under alfalfa, and the impact of culture on the accumulation of nitrogen in the soil
The article presents the studies that were conducted in 2011-2014 agricultural years in the experimental rotation hospital departments of Agriculture and Agricultural Chemistry, located in the Experimental Station of Stavropol State Agrarian University. The hospital is part of a geographical network experiments with fertilizers and registered in the register of long experience certificates of GeoNetwork VNIIA of the Russian Federation. We have presented an influence of systems of fertilizers and tillage practices on yield, indicators of the structure and quality characteristics of winter wheat of Zustrich varieties grown after pea predecessor in a stationary experience of Stavropol GAU. The influence of fertilization systems built on different principles on the productivity of winter wheat after pea predecessor in the area of unstable moistening was studied. The article has practical significance, since on the basis of the research we have found experimental evidences to recommend a cash-balance method for determining fertilization rates for the construction of the settlement system of fertilizers, to assure maximum efficiency and provide a level of skill programming yield 90-100%. We have also offered low-cost bio- fertilizers in crop rotation system, based on the efficient use of organic fertilizers, local application of minimal doses of mineral fertilizers
