| description | The invention provides a ventilating method for the warming retention and improvement of air quality of sheepcot in winter, which comprises the following steps of: digging ventilation openings on each wall surface with the area of 10 to 12 square meters in the sheepcot at intervals of 5 to 6 meters at the position 0.2 to 0.3 meter away from the ground; ventilating for 0.8 to 1.2 hours at 1:00 to 3:00 in the afternoon, so that the humidity and the content of harmful gas in animal houses are reduced, and the warming retention effect is also achieved, wherein the size of the dug ventilation openings is 30 centimeters in length, 50 centimeters in width and 40 centimeters in height. By the method, the humidity of air can be reduced from 74.9 percent to 68.2 percent, the ammonia level is reduced from 44.51 milligrams/M to 30.65 milligrams/M , the sulfur dioxide level is reduced from 0.0042 milligrams/M to 0.0025 milligrams/M , and the carbon dioxide level is reduced from 2,227 milligrams/M to 1,833 milligrams/M ; a |
