Abstract:
The article presents the results of a full-fledged growing season of cucumber plants of the Svyatogor F1 variety under photo-culture conditions. The studies were carried out on an experimental research hydroponic installation (ERHI) under photosynthetic photon irradiation EPPFD = 250 ± 10 μmol / c·m2. In the experiment, we used phyto-irradiators (PI) with high-pressure sodium lamps (HPSL) of the DNaZ type (control version), as well as light emitting diode (LED) phyto-irradiators (PI) of the combined spectrum. Together with specialists from the agro-technical complex of the State Unitary Enterprise of the Republic of Mordovia “Teplichnoye” a methodological approach was developed for conducting photo-biological research in the artificial climate laboratory of the FSBEI HE National Research Ogarev Mordovia State University, which allows to determine the radiation effect of LED PI of the combined spectrum on the productivity of cucumber plants under photo-culture conditions. Based on the conducted photo-biological research, it was found that the variant of the emission spectrum of PI2, in which the radiation with = 730 nm was 3.1 times greater and the radiation with  = 660 nm was 1.23 times less than in the emission spectrum of PI3, turned out to be more effective, providing not only the best quality of seedlings of cucumber plants, but also showing higher productivity. It was revealed that partial overlap of functions, synergy and multiple interactions between different systems of radiation perception can cause an ambiguous response of plants to changes in the conditions of technological irradiation. The practical significance of the obtained results was shown.
