Abstract:: In allusion to the existing problem of labor intensity of artificial ventilation control，uneven distribution temperature within greenhouse and other issues，two or three intelligent roof ventilation devices were installed in order to compare with artificial ventilation control with two or three segmented intelligent ventilation inside a greenhouse in winter in Beijing.The results showed that during the heat insulation cover opened，the difference between the maximum and minimum values of air temperature in the greenhouse was (2.3±1.1)℃ of two-stage control range,(1.1±0.5)℃ of 3-stage control range，and (3.8±1.3)℃ of manual control rang；economy benefits could significantly be increased about 9,700 RMB per 667 m2 of cultivated area by using intelligent roof ventilation.Therefore，intelligent roof ventilation segment systems were used to test indoor environment of greenhouse in order to contrast analysis of manual control and intelligent mechanical ventilation effect in winter in Beijing.Therefore，uniformity of the indoor temperature and growing income could significantly be improved by intelligent roof ventilation.
