PLANT AND MUSHROOM GROWING GREENHOUSE Russian patent published in 1997 - IPC

FIELD: agriculture, in particular, plant growing in protected ground constructions. SUBSTANCE: greenhouse has microclimate parameter regulation system, mushroom cultivation departments 7 with vegetative sections and plant cultivation departments 4 with vegetative units, roof safety device 1 with troughs and ridges and base 3. Roof safety device has sections with ridge members 10 and water-collecting chutes 11 positioned above them. Arced cross bars 5 of vegetative units have radius R equal to width of roof safety device 1. One cross bars 5 intersect adjacent cross bars and connected with ends of cross bars of subsequent units. Cross bar intersection points are positioned below ridge members 10 and joints are arranged below water collecting chutes 11. Vegetative units are provided with conveyor 12 and plant chutes 6 pivotally secured on conveyor 12. Optical radiation sources of microclimate parameter regulation system are positioned at locations selected in accordance with greenhouse spans. Channels 15,19 are laid under greenhouse base to carry conveyors 16 with mushroom cultivation chutes 18. Channels 15,19 are isolated from greenhouse space by light-impermeable perforated covers, with cover perforations being adapted for communication with compressed air sources. Such construction of greenhouse allows yield to be increased by 10-15%. EFFECT: wider operational capabilities, reduced cost by eliminating necessity for construction of separate mushroom growing house and creation of air climate common for both vegetables and mushrooms, and increased yield. 3 cl, 3 dwg
