The invention relates to a quick Rosa Damascena Bulgaria breeding method capable of generating air through photoautotrophy. The method comprises the steps of treatment of a seedling bed, treatment ofin-vitro branches, cutting and management after cutting, wherein according to treatment of the seedling bed, a medium prepared from agricultural waste straw, vermiculite, perlite and ferric oxide hydrate is put into inverted seedling pots, and then the inverted seedling pots are fixed to horizontal tube type or tank type or box type air seeding culture solution cycle supply devices with through holes reserved in the upper portions, all the air seeding culture solution cycle supply devices are erected in a three-dimensional tread shape, water pumps are connected with a water storage tank with aheater and an agent feeding inlet, and an LED cold light source is arranged above the seedling bed; according to management after cutting, after cutting is finished, a seedling solution is circularlyand alternately injected into or drawn out of the air seeding solution cycle supply devices by using the water pumps, and root promoting and sterilization are conducted by using the seedling solutionand dry air. By means of the method, the production time is greatly shortened, the seedling production efficiency is improved, the application range is wide, the method is less affected by environment intervention, the yield per unit area is high, and the seedling quality is high.
