Наиболее дешевый способ генерирования оптического излучения – с помощью натриевых ламп высокого давления. Однако их спектральный состав не в полной мере приемлем для светокультуры. Светодиоды позволяют задавать практически любой спектр, но их стоимость достаточно высока.</p><p>(Цель исследования) Теоретически и практически обосновать спектральный состав светодиодного излучателя-корректора, используемого в светокультуре дополнительно к натриевым лампам.</p><p>(Материалы и методы) Экспериментально изучили эффективность комбинированного облучения в лаборатории энергоэкологии светокультуры Института агроинженерных и экологических проблем сельскохозяйственного производства  при облучении рассады томата сорта Благовест. Исследовали биометрические показатели растений. Производственный эксперимент проводили в тепличном комбинате Межвиди (Латвия) на взрослых растениях томата сорта Encore для трех вариантов: первый – под натриевыми лампами; второй – со светодиодными облучателями; третий – при комбинациии натриевых ламп и корректора. Влияние облучателя на растения оценивали по величине  флуктуирующей асимметрии билатеральных признаков листовой пластинки.</p><p>(Результаты и обсуждение) Определили, что применение корректора улучшило биометрические параметры рассады: увеличило число листьев, их сырую массу, содержание в них хлорофилла и сухого вещества. Отметили, что в теплице наименее благоприятная световая среда формируется под натриевыми лампами, а светодиодные облучатели создают более комфортные условия. Подтвердили, что применение корректора обеспечивает наилучшую световую среду. Выявили повышение урожайности плодов томата и их вкусовых качеств при использовании комбинированного облучения.</p><p>(Выводы) Доказали, что для коррекции спектра лампы ДНат 400 необходим фотонный поток корректора 71,2 микромоля в секунду, при этом отношение потоков синих и дальнекрасных светодиодов должно составлять 64 и 36 процентов соответственно.</p></abstract><trans-abstract xml:lang="en"><p>Effective cultivation of plants with grow light is possible only under optical radiation of a certain spectral composition. The cheapest way to generate optical radiation is with the help of high pressure sodium lamps. However, their spectral composition is not fully acceptable for grow light. LEDs allow you to set almost any spectrum, but their cost is quite high.</p><p>(Research purpose) To prove the spectral composition of the LED emitter-corrector used in grow light in addition to sodium lamps theoretically and practically.</p><p>(Materials and methods) The authors experimentally studied the effectiveness of combined irradiation in the Laboratory of Energy Ecology of Grow Light at the Institute of Agroengineering and Environmental Problems of Agricultural Production under the irradiation of Blagovest tomato seedlings. They investigated the biometric indicators of plants. The production experiment was carried out in the greenhouse plant Mezhvidi (Latvia) on adult Encore tomato plants for three options: the first – under sodium lamps; the second – with LED irradiators; the third – with a combination of sodium lamps and corrector. The effect of the irradiator on the plants was evaluated by the magnitude of the fluctuating asymmetry of bilateral signs of the leaf blade.</p><p>(Results and discussion) The authors found out that the use of the corrector improved the seedlings biometric parameters: increased the number of leaves, their wet weight, the content of chlorophyll and dry substance in them. It was noted that in the greenhouse the least favorable light environment was formed under sodium lamps, and LED irradiators created more comfortable conditions. They confirmed that the use of a corrector provided the best light environment. They revealed an increase in the yield of tomato fruits and their taste when using combined irradiation.</p><p>(Conclusions) The authors proved that to correct the spectrum of HPS lamp 400, a corrector photon flux of 71.2 micromoles per second is required, while the ratio of blue and far-red LEDs fluxes should be 64 and 36 percent respectively.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тепличное производство овощей</kwd><kwd>светокультура</kwd><kwd>освещение в теплицах</kwd><kwd>светодиодные облучатели</kwd><kwd>комбинированное облучение томатов</kwd><kwd>натриевая лампа</kwd><kwd>светодиод.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дорохов А.С., Гришин А.П., Гришин А.А.
