摘　　要：以连栋日光温室内无土盆栽红掌为试材,根据控制灌水下限占田间持水率90%、80%、70%、60%和50%的比例设置5个处理,系统研究了滴灌条件下气象因子对红掌耗水规律的影响,探讨了Penman-Monteith模型对设施无土栽培红掌耗水的预测。结果表明,供试条件下红掌日耗水量分阶段结果为:移栽至8月中旬0.2～0.4mm/d、8月中旬至9月初0.2～0.5mm/d、9月初较低为0.1～0.3mm/d、9至10月中上旬0.6mm/d左右;在试验期间5个处理的红掌耗水总量分别为42.4、37.7、40.2、41.2、36.1mm;Penman-Monteith模型能够预测设施无土栽培红掌蒸发蒸腾量。The experimental Anthurium of this paper was cultivated in multi-span greenhouse and planted in plastic pot with substrate. The five treatments were based on the proportion of low irrigation limit with field moisture capacity, the proportion was 90%,80% ,70% ,60 % and 50% from T1 to T5. Result showed that the daily water consumption amount fluctuated from 0.2 to 0.4 mm/d before middle August, from 0.2 to 0.5 mm/d during middle August and the primary stage of September. The highest daily water consumption amount was about 0.6 mm/d. The Anthurium water consumption amount was about 36. 1 to 42.4 mm during experiment. Compared with T1, the water consumption amount decreased 11. 0%, 5.2 %, 2.9 % and 14.8 % from T2 to T5. Penman-Monteith model could be used to calculate the evaportranspiration of Anthurium.
