ABSTRACT:
Water consumption can be reduced by using a greenhouse for agriculture in
desert areas. We analyzed the effect of control of ventilation, sprinkler
water, and solar radiationshielding on changes of temperature
and humidity in a greenhouse under various desert area conditions. We calculated
the changes in temperature and humidity in a greenhouse for a whole day in four
seasons, and the calculation results of water consumption with and without a
greenhouse were compared. When ventilation, shielding, and sprinkler water were
controlled under suitable conditions to grow orchids in a desert area, water
consumption in July was only 7% of that without a greenhouse.
