【 摘 要 】

The work presents the results of an experiment studying the effect of radiation spectral content (considering its equal intensity in terms of photosynthetically active radiation) on the growth and development of greenhouse model plants. The results demonstrate that the effective development of model subjects requires the adaptation of radiation spectral content according to the growth period and plant type, unlike the illumination level. The obtained results demonstrate the necessity of the creation of adaptive irradiation unit.
