FIELD: agriculture. SUBSTANCE: method involves using gas mixture to heat incandescent body 7, which emits heat and light beams 8 onto plants 9. Combustion gas is directed through heat-exchanger and further via double-walls 2,3 is discharged outside through opening 1. A portion of combustion gas is delivered from combustion chamber 4 into hothouse. Carbon dioxide present in combustion gas is used to feed up plants. Thus, in the process of combustion of gas mixture the plants obtain simultaneously heat, light and feed up, which are necessary for growth of plants. EFFECT: increased efficiency, simplified construction and improved plant growth conditions. 7 cl, 1 dwg |
