1 | On the example of cultivation of sprout cabbage of a kind «Nadezhda» in the summer period influencing of meteorological conditions 1999-2003 years to productivity of correction light films for protection closed soil is investigated. With usage of techniques of biological testing of films is rotined, that challenging influencing to growth and development of plants («polysvetany» effect) correction light films render only at enough favorable temperature and light meteorological conditions, giving considerable effects of increase of biomass of spout and economic productivity of horse radish. At a decrease of mean temperatures on 5-7 °C or increase of temperatures on 8-10 °C from optimum for cultivation of plants and long-term period of dense cloud cover during realization of experiment in conditions of closed soil without an auxiliary illumination and heating «polysvetany» effect is not watched. Reproduction of effect in region of risky agriculture (Tomsk) in the indicated term is reached 40% in most unfavorable for an agriculture spring period and 75 % in the summer period | 956 | ||||
2 | The research of features of fluorescence of dispersed photosphors in conducted on the basis of organic and inorganic connections of a europium and polymer films with their components at excitation of solar radiation. The excitation of luminescence of phosphors by UV radiation of the sun does not change spectral content of luminescence radiation. For number of photophosphors on the basis of ocsysulfide of yttrium, activated with europium watches change of intensity of minor bands in luminescent spectrum concerning the principal band, that it is necessary to allow for consideration of photophysical characteristics of corrective light films with their components. The obtained data allow to conduct calculation of intensity of luminescence radiation under corrective light films with allowance for its spectral content | 1000 |
