The invention relates to a steel frame greenhouse technology for peach tree in low-latitude plateau area. The technology is characterized in that steel pipes are welded to form a semicircular steel frame greenhouse to be fixed to the peach tree farmland a plastic greenhouse film and an inspect proof nets cover the frame a nonwoven fabric covering surface is hung in the greenhouse the plastic greenhouse film and the nonwoven fabric are contracted and stretched to realize the control to the temperature in the greenhouse of the peach tree at different growth periods and under the changeful air temperature condition at the low-latitude plateau area meanwhile, an underground irrigating device, a novel double-layer ground film and a special fruit bag and other technologies are adopted, thus the damage factor under the natural condition is removed, the natural growth state of the peach tree is remained to the maximum, and the quantity of applied pesticides and chemical fertilizers is greatly decreased the water for irrigating is about 40% that under the common planting condition, and the output is more than 150% that under the common planting condition in addition, the peach quality is far more than that of the common peach, and the market price is 5 times that of the common peach.
