SUBSTANCE: invention relates to the field of lighting technology and may be used to grow crops under artificial lighting. In method intensities of light flow and spectral composition of light source are periodically changed. Illumination of plants in sheltered ground structures is realised on the basis of principle of doubling natural daily rhythm due to smooth changeover of illumination level from night to day and back. Changeover takes place twice a day, with account of change in moon and sun spectra of radiation. Besides peaks of maximum daily illumination correspond to moments of upper, daily, and lower, night, culminations of sun. Ratio of light and dark periods duration depends on extent of vegetative ripeness and type of grown crops.

SUBSTANCE: according to the method regulation for this type of plant values of percentages of energy in various spectral bands of photosynthetically active radiation (PAR) are set. Range of PAR is isolated from the total flux, energy flow in separate spectral bands of PAR is measured. The percentages of energy in various spectral bands are calculated in relation to the energy of PAR. The value of flow energy consumption of optical radiation is determined by the formula where and are respectively, regulatory, and measured percentages of the energy flux of radiation in the i-th spectral band.

At that in preliminary experiments different ratios of one deal of one of the light sources in the general flow are imposed. Values of combination coefficient of sources flows in the general flow are calculated for the given ratios according to the formula , where ΦA, ΦB are respectively flows from sources A and B; the spectral fraction of the overall flow is calculated according to the formula where , are respectively the deals of flows in the i-th spectral ranges of sources A and B. Values of energy consumption are calculated by the formula , where are normalised values for the irradiated crops. The functional dependence of the energy consumption from the flow combination coefficient rate εµ=f(µ) is determined. Radiation regime is set at the value of the combination coefficient of flows, as corresponding to a minimum on the obtained functional dependence by changing the deal of flows from used light sources that form irradiance at the site of growing plants.
