METHOD FOR GROWING PLANTS IN CONDITIONS OF PROTECTED GROUND, DEVICE FOR GROWTH OF PLANTS IN CONDITIONS OF PROTECTED GROUND AND COLLAPSIBLE MULTI-TIER RACK FOR GROWING PLANTS IN CONDITIONS OF PROTECTED GROUND Russian patent published in 2010 - IPC A01G9/00 A01G9/24 

FIELD: agriculture.

SUBSTANCE: group of inventions relates to the field of agriculture and crop sector. Method includes arrangement of trays to make vertical tiers, cultivation of plants, maintenance of required light mode in greenhouse, the latter of which is supported by displacement of light source between tiers of trays. Plant seedlings are planted into vegetation trays, required climatic mode is created, at the same time source of light in the period of radiation is moved by continuous reversible motion up and down between extreme tiers, and speed of light source motion and capacity of light source are established depending on extent of natural illumination and/or air temperature. Device comprises system of plants cultivation, including vertical multi-tier rack installation for vegetation trays with plants, systems for maintenance of required climatic and light modes, the latter of which includes at least one source of light arranged with the possibility of displacement up and down between tiers of rack installation, comprises facility that provides for continuous reversible motion of light source between tiers in the period of plants radiation. Rack comprises sections of shelves that are mounted in tiers on four stands. Sections are combined into modules, every of which includes three serial stages arranged in a row, two extreme ones and one central, joined to each other by means of a hinge with the possibility of extreme sections rotation around vertical axis to center of module to form a "П"-shaped profile.

EFFECT: usage of group of inventions makes it possible to speed up development of plants due to provision of even illumination of plants, increasing density of photosynthetic flow of photons, elimination of overheating and damages of grown plants leaf canopy and reduction of light losses.
