Abstract:
In order to study the influence of solar assisted heating system on greenhouse temperature and ground temperature under different heat dissipation modes.In this study,through the comparative test method,we analyzed the heating effect of the wall heat dissipation mode,the ground heat dissipation mode,the wall-and-ground heat dissipation mode on the greenhouse temperature and the ground temperature.The results showed that:with the comparison between the test area and the contrast area,the average air temperature in the wall heat dissipation mode increases by 3.6 ℃,and the average ground temperature increases by 1.3,1.0,0.6 ℃ at the position of 0.1,0.3,0.5 m,respectively;the average ground temperature in the ground heat dissipation mode increases by 0.9 ℃,and the average ground temperature increases by 2.5,3.3,4.1 ℃ at the position of 0.1,0.3,0.5 m,respectively;the average air temperature in the wall-and-ground heat dissipation mode increases by 2.1 ℃,and the average ground temperature increases by 1.8,2.3,3.2 ℃ at the position of 0.1,0.3,0.5 m,respectively.
