FIELD: crop production.
SUBSTANCE: high bed contains an energy-intensive circuit, which includes: a fence, in a limited space of which planting soil is filled; through channels having an input and output device of the air energy carrier; fan heater, through which air is pumped and pumped through the through channels. The bed is made with the possibility of moistening its soil. The fence is made in the form of a collapsible structure, consisting of assembled into one or more horizontal rows connected to each other in the vertical direction, assembled from modules made of a material having high thermal conductivity. In the middle part of the modules, horizontal longitudinal open channels are made, which are closed after connecting the modules in the horizontal direction from their open, outward-facing side of the bed, attached to the modules made of a material with low thermal conductivity, with protective external screens, thus forming a horizontal internal through closed channel, passing in each individual horizontal row of modules around the entire perimeter of the bed, made up of channels made in modules that are connected to each other by means of branch pipes of the inlet device, connecting and corner units of the bed fence. The modules have perforations for draining the water condensate formed during the cooling of the heated air when transfer the heat to the soil and the space around the bed, moistening the soil of the bed. The bed is configured to control the bed soil temperature until a temperature range favourable for plants is reached by pumping air with a fan heater in the heating or ventilation mode through the internal through channel of each individual horizontal row of modules in its enclosure.
EFFECT: creation of a universal design that provides for quick assembly and disassembly of the bed during its formation and changing the size of the bed in length, width and height, if necessary, effective adjustable heating and cooling of the fertile soil layer of a high bed from the sides depending on the level of soil temperature, effective moistening soil beds without the use of special equipment.
