IMPROVEMENT OF IRRADIATOR’S SYSTEMS OF A HOTHOUSE OF AN AGROINDUSTRIAL COMPLEX
Abstract
The necessity of scientific ground and development energyeffective lightning technology an equipment with the modern high-efficiency sources of radiation with the favourable spectral distributing and making on their basis new flowsheet of light culture plants, which will allow considerably to reduce the energy consumption of the irradiation settings and promote the productivity of plants at growing of them in the closed soil is rotined. The power and lightning technology parameters of the most widespread hothouse systems of lightning technology of permanent irradiation are analysed. On the basis of experimental researches set, that most perspective for perfection of power providing hothouse systems is growing plants in variables light fields with halogens arc and sodium lamps of high pressure. The method of comparative analysis of irradiation settings efficiency with different actinogens and methods of irradiation is offered. The calculation of power expenses during exploitation of the irradiation settings of permanent and variable irradiation is conducted. For research of variable irradiation settings with precession, circulating, hesitating and recurrent-forward motion of irradiator were offered. The use of the offered settings allows to decrease expenses materials and production capacities on making of necessary amount of irradiators. It is set as a result of research, that the most economy of electric power is arrived at use of the irradiation settings with irradiator’s rotatory motion at the irradiation of horizontal plane. At growing of potato escapes in vitro use of variable irradiation settings is allowed to decrease energyexpenses in 2,3-2,4 times by comparison to a permanent irradiation.Key words: lightculture of plants, efficiency of energy, irradiations level, photosynthesis active radiation flux, irradiator, irradiation device.
