摘　　要：提出利用植物气生根的生理功能对空气进行除湿,研究植物气生根在晴天和阴天两种不同天气下的吸水量和降温效果;研究了被处理空气的温度、含湿量和环境的温度、含湿量在一天中不同时刻对植物气生根吸水量的影响。结果表明,晴天时榕树气生根总除湿量平均值为7.94g/kg·干,最高可达11.45g/kg·干;平均每个气生根的除湿量为0.159g/kg·干。在晴天,榕树气生根吸水量受环境温度、相对湿度影响非常显著。A new way of air dehumidification by the aerial root is proposed,and the experimental device is designed for studying the effect of water absorption and cooling by plant aerial root in the sunny or the cloudy.The temperature and moisture content of the treated air and the environment affect the water absorption of aerial roots at different time of day.The results show that the average amount of dehumidification for ficus microcarpa＇s aerial root is 7.94g/kg in sunny weather,and the maximum amount is as high as 11.45g/kg.The water absorption for each aerial foot is 0.159 g/kg.The water absorption is affected by environment temperature and relative humidity markedly in sunny weather.
