Abstract:
The microclimate environmental factors in Northwest type XB-GII solar greenhouse was observed,including the temperature of indoor and outdoor,the temperature of wall and ground in different depth,the heat flow of wall and ground,the light intensity of indoor and outdoor etc.The results of observation and analysis showed that the minimum temperature difference could reach 32℃ between indoor and outdoor for this northwest type XB-GII solar greenhouse.The temperature of indoor keeping in more than 20℃ could be 6 hours in sunny days.The ground temperature of 30 cm depth and the wall temperature of 30 inside could keep constant basically between day and night.The results of heat flux variation analysis showed that the soil was the main heating body of solar greenhouse,the wall came second.The management of solar greenhouse should pay attention to the ventilating and cooling during the day,and the covering of thermal insulation during the night.
