DEPENDENCE OF GRAIN FLIGHT RANGE ON THE CONSTRUCTION PARAMETERS OF THE REFLECTOR DURING WITHIN SOIL SURFACE PLANTING

Posted in 2017, AGRICULTURE, Issue № 6(60) June 2017 | 0 comments

At present, one of the key factors in the cost of products related to agriculture is its energy output ratio. To be more precise this key factor is the amount of energy spent on producing a unit of production. Unfortunately, our producers significantly lag in terms of this indicator in comparison with their Western counterparts. Of course, the geographical position and climatic conditions of the location of the majority of our agricultural producers have a significant influence. However, one cannot deny the shortcomings in the technologies and technical devices that are used.

The most important factors of economic efficiency in the context of a market economy are economic feasibility and the competitiveness of the products.

Modern science and best practice have shown that when creating necessary conditions for growth and development, agricultural plants have large reserves of increasing yields. One of the reasons for low competitiveness of domestic agricultural production is the excessive cost of cultivating crops due to the lag in scientific and technical equipment, the use of obsolete technologies and highly energy-intensive technical means.

The work contains theoretical prerequisites for determining the range of flight of wheat grains with the approach to real conditions by means of additional factors influencing the flight range and allowing to determine the design parameters of the grain reflector within the soil surface planting.

APPLICATION OF HIGH-FREQUENCY EFFECTS TO REMOVE GROUND ADHESION ON MACHINES WORKING BODIES

Posted in 2017, AGRICULTURE, Issue № 5(59) May 2017 | 0 comments

This article examines the use of piezoceramic emitters for controlling adhesion of soil to the working bodies of earth-moving machines. Also an experiment was performed and the experimental data was obtained. After further processing of patterns a graphical interpretation of the effect of piezoceramic emitters was obtained. Subsequently, it was concluded that the use of piezoceramic emitters is more preferable in terms of compactness and equal spacing on the surface of the working body than, for example, the use of the currently existing means for heating the ladle or vibration exposure. It has been shown that the technical performance of the machines with the intensifying device to reduce adhesion of soils when working on wet ground at a negative temperature is 1.2…1.4 times greater than the machines not equipped with such a device, i.e. there is economic impact of their implementation due to increased productivity.

GROWING OF MOWN GRASS STANDS WITH MEDICAGO POLYMORPHA UNDER THE CONDITIONS OF THE LENINGRAD REGION

Posted in 2017, AGRICULTURE, Issue № 5(59) May 2017 | 0 comments

The paper is devoted to a comparative assessment of legumes and legume-grass stands with various sorts of medicago polynorpha in cultivation under the conditions of the Leningrad Region. Taking into account the orientation of the agriculture of the North-Western region of Russia to the dairy and meat specialization, the most important task is the need to produce cheap, high-quality and well-balanced fodder in sufficient quantities. When choosing a legumes component, a preference should be given to long-term species, since they provide the cheapest feed. Currently, clover is the most widespread legume in the region when making a fodder base. However, despite the high potential yield and fodder dignity, it is characterized by a small longevity. Therefore, other legumes species are used, for example, alfalfa. Cultivation and use of legumes and legume-grass stands with medicago polynorpha under the conditions of the Leningrad Region, in spite of a number of difficulties associated with the high acidity of the soil, is an actual trend. The paper presents the results of research on the cultivation of medicago polynorpha in its pure form and in a mixture with cereals, conducted on the basis of the St. Petersburg State Agrarian University.

CONTENT OF POTASSIUM IN SOIL WITH THE USE OF RESOURCE-SAVING TECHNOLOGIES

Posted in 2017, AGRICULTURE, Issue № 4(58) April 2017 | 0 comments

It is customary to judge the fertility of soils, the integral index of which is the yield of top, both in natural biocenose and in agrocenose, based on the hydro-physical and agrochemical properties. Agrochemical parameters of effective fertility are mobile forms of mineral nitrogen, phosphorus and potassium. The content of potassium in soil depends on the soil-climatic conditions to a larger extent. The article discusses the effect of the soil treatment system in grain steaming rotation on the content of potassium in soil on the precursors of pure and sideral steam. The research was carried out at Kemerovo Research Institute, a branch of the Russian Academy of Sciences. Close relationship between the K2O content and moisture content in July and August (at hydrothermal index above 1), r=0.5200-0.8387 was established. When there is a lack of moisture, this relationship is reduced or absent. During two crop rotations irrespective of the soil treatment system, the content of mobile potassium is higher for the precursor than the sowing steam (clover) – 100-108 mg/kg soil; the combined minimal and minimum tillage systems have the advantage. The share of the predecessor’s influence on the content of mobile potassium in soil comprised 13.2%, the soil treatment system – 4.0%, crop rotation – 49.1%, relation between crop rotation and predecessor – 17.9%.

ROLE OF FIRES IN RENEWAL OF SUBORDINATE SCOTCH PINE

Posted in 2017, AGRICULTURE, Issue № 4(58) April 2017 | 0 comments

The results of Scotch pine natural regeneration study at fire-sites in sub taiga of the northwestern part of the Eastern Sayan are presented in the paper. It was found that the strongest fire exposure have a positive effect on forest formation of mixed herbs forests. Strong fire creates favorable conditions for the settlement of a new generation of forest species. Post-fire regeneration illustrates high potential of burnt ecotope regeneration. Strong fires mineralize soil organics and eliminate competitive environment of the indigenous ecotope giving positive dynamics to the succession process – the area is overgrown by willow-herb burns. Seedling growth of 4-5 years of age is characterized by high density, uniform distribution in the area and has good biometric indicators. The findings suggest favorable development of the initial research phase in forest formation in the examined burnt environment. The materials of field studies will help to determine measures necessary to promote natural regeneration of areas with dead planting in order to restore their biota.

Posted in 2017, AGRICULTURE, Issue № 4(58) April 2017 | 0 comments

We have analysed growth dynamics of the Siberian stone pine of different geographic origins in the Training and Experimental Forestry Facility of SibSAU under the planting scheme of 2×1 m. The variability of the growth rates of the offspring of 11 populations aged 28 – 47 is determined. At the age of 47, the trees had an average height of 12.8 -18.5 m with a trunk diameter ranging from 8.3 to 16.8 cm, depending on geographic origin. High level of variation in the height and diameter of the tree trunk was observed in some variants (> 40%). The largest diameter of the trunk is that of the trees of Chita, Shumikhinsky, and Altaic (Kurly) origin. The intensity of plant growth at the age of 28 – 47 is significantly influenced by the geographical origin with the establishment of a change in ranks due to high competition of trees under the conditions of high planting density.
