SUBSTANCE: greenhouse has a framework manufactured from profile metal elements connected with one another with screw anchoring elements. The greenhouse has posts, horizontal longitudinal beams attached to the posts, oblique and horizontal flooring joists connected with one another as well as with the posts as transverse triangular bents secured on the posts. The upper part of the bents carries roofing panels with transparent films. The greenhouse is equipped with roofing film coating with adjustable area. The coating is made as rolls carrying transparent film. The rolls are mounted with an ability to roll and unroll the film on the ceiling of the greenhose by means of a mechanism equipped with flexible tractional straps. The staps are connected with the elements of the roll structure, reeved through the block mounted inside and outside of the greenhouse and carry counterbalances on the free ends of the handle. The rolls are made as a cylindrical body coupled with pivot bolts on the ends and mounted with a capacity to rotate relative to the pivot bolts with a controlled value of slowdown, to set up tension of the film while unrolling the roll. The film is made with flexible bands attached to it with a sticker to prevent sliding of the roll along the ceiling while reeling the film.

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.
EFFECT: method makes it possible to increase crop capacity by optimisation of light mode, to increase speed of plants growth, to reduce consumption of electric energy, as well as to expand range of application.
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.
EFFECT: method enables to increase the information content at measurement of value which characterises the energy efficiency of irradiation process.

The spectral parametres of the flow are created that affect the plants by combined effect of several light sources of different specters. 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.
