The Technology Of Planting Potatoes In The Farm

Adelaide begins to farm planting. Spring field work begins with the harrowing of the soil to retain moisture that has accumulated in autumn and winter. In the Kherson region under harrowing early potatoes not conduct, and immediately prepare the ground for planting. This is due to a sufficiently early time frame fit, as well as a decrease of mechanical load on the soil. Each successive soil pereuplotnyaet operation and destroys the structure that unacceptable for the potatoes. An important element is the technology of potato preplant tillage.

The purpose of pre-plant – to create a stable "melkokomkovuyu" soil structure with sufficient amount of time and good contacts with the lower water storage layers. The soil in the spring should be treated only to the required depth to reduce water loss, in the area, is a limiting factor. The farm uses complex machines with shaped teeth, spring harrows and rollers. Cultivation is carried out at a depth of 12-14 cm, it provides the necessary loose soil structure, prevents excessive moisture loss as compared to milling and get high performance. It is very important to ensure optimal density plantings. It depends on several factors, the seed crop is is 50-57 thousand. 1 hectare, while the commodity crop that ranges from 38 to 45 thousand.

1 hectare. Should take into account the fraction of planting material, tubers with small fraction (less than 35 mm) planted density of 40-45 thousand pcs. 1 ha, with an average (35-55 mm) fraction of 38 – 42 thousand. 1 ha, and large (55-75) – 33 – 38 thousand. 1 ha. Among the varieties of potatoes are planted on the farm are as follows: in the early group – Rivera, Ariel, Karatop, Erou; group average maturity – Molly, Courage, Roco, Romantsev, technical grade – Karlen, pyrrole, Bonus. Optimal timing of planting potatoes occur upon heating the soil up to 5-8 C at a depth of 10-12 cm in the Kherson region for early production run certain risks, planting potatoes in the early period, this period is 2-3 decade of March.

Energy and Industry of Russia Welcome to our Website 'Energy and Industry of Russia "to help students and engineers – heating equipment, power engineering and other technical specialists specialties operating the power station, power plants, nuclear power plants and other industrial enterprises of our country. Represented on our site: e-books, lectures, courses and degree projects on thermodynamics, heat, steam and gas turbine thermal power plants electrical engineering, hydraulics, automation and instrumentation, boilers, water treatment, district heating, energy, pumps, economy, ecology, renewable energetike.Takzhe presented: energy news, magazines Energy, power equipment catalogs, drawings, boilers, turbines, reactors, thermal and nuclear power plants CHP schemes, regulations and programs. What is energy? For the average person – it's light and heat. To an outsider Observer – power plants, pipes, cooling towers, thousands of kilometers of high voltage transmission lines. And for a person working in the industry, energy – it's entire life.

Energy consumption is a prerequisite for the existence of humanity. Availability of affordable energy to always be necessary to meet human needs, prolonging and improving their living conditions. The history of civilization – History invention of new and innovative methods of energy conversion, the development of new sources and, ultimately, increase energy efficiency. The first jump in the growth of energy consumption occurred when the man learned to extract fire and use it for cooking and heating their homes. Energy sources in this period were wood and the muscular strength of man. The next important step is associated with the invention of the wheel, creating a variety of tools, the development of forging. .

The use of insulated wires in the southern and mountain areas do not a problem, because The effect insulation resistant to ultraviolet light and ozone. The need for insulated wire medium-voltage cable design has been implemented SAX. The first installation of insulated Wire VL-20 kV implemented in 1976 – the so-called PAS system – reinforced aluminum wires in the plastic insulation. Later, in 1981 in Finland was built the first line of SAX, where the wire insulation was made of polyethylene. In 1984, the operation of the system adopted vibrationproof SAX, also equipped with security devices from an electric arc. The system currently includes SAX and includes secure the wires with insulation silanosshivaemogo polyethylene, equipped with the corresponding linear-coupling valves, devices, lightning protection, vibration protection and mounting accessories related to them. In Sweden, first appeared in the VLZ 1985 – 3000 km, Norway VLZ first – in 1986 built 2,000 km.

Since in the 90s and the wires AMKA SAX were available and successfully used in Russia, now NOKIA KABEL in 1995 initiated the development of the company ORGRES set of normative and technical documentation for design, construction and operation of pilot lines The effect of 0.4 kV, and in 1996 – the same type of documentation VLZ 6-20 kV. Currently, rules already in place devices up to 1 kV The effect of CIP, as well as Rules for Design VLZ 6-20 kV. Design and development of domestic SIPs were launched in 1987 at the Irkutsk factory cable. In 1991, the TU-120 16.K71-91 were put into experimental production of wire marks SAPTA, SASPt, SAPssh and SASPssh.
