FIELD: agriculture. SUBSTANCE: method involves providing convective heating of air by direct burning of gas in microflame burners positioned within greenhouse or radiant heating by burning gas in radiation burners. At soil thawing out and heating stage, ratio of total radiant and convective heating components is (3-5):1. At sowing to germination stage, this ratio is (4-6):1, and at seedling growing stage, this ratio is gradually decreased to (0.05-0.2): 1 in reverse proportion to tenfold coefficient of coverage by projection of plant green mass of soil area, with correlation coefficient being 0.5-1. Then radiant heating process is stopped. EFFECT: increased efficiency and reduced operational costs. 5 cl, 3 dwg
