FIELD: agriculture. ^ SUBSTANCE: agro-complex contains plots of land with separating ditches. Agro- bridges are installed on permanent operating track. Mobile greenhouses are also installed on their permanent operating track. Greenhouses are represented as several sections of arch rigidly interconnected on top. Each arch ensures coverage of at least two plots of land for the received shift of crops. Vertical walls of greenhouse are rigidly fixed to the upper parts of sections along the perimeter; vertical walls are also rigidly fixed to upper ceilings of greenhouses and connected to each other. Rolling contact bearings are fastened at both ends of greenhouse and in symmetrical alignment at two sides of end walls so that can be removed. Rolling contact bearings are installed inside greenhouse along separating ditch axis, in symmetrical alignment and at equal space. Bridges are mounted on separating ditch. Rolling contact bearings are fixed to vertical supports as removable elements connected to upper ceilings of greenhouse. Permanent track rails for agro-bridges are installed flush with soil level along short and long sides of land plots. Lower crosscut of all greenhouse walls along the whole perimeter is provided with movable heaters having mechanical drives. Heat generators are placed inside greenhouse corners along one of diagonal. Heat generators are fixed to greenhouse structures so that they can be removed and controlled automatically from on-board computer. Rolling contact bearings displaced along long sides of greenhouse are implemented as rollers with diameter being less than diameter of other rolling contact bearings. ^ EFFECT: increase of agro-complex output. ^ 3 cl, 5 dwg
