摘　　要：采用FAO—56推荐的方法,计算贵州省的参考作物每日蒸散量。根据烤烟不同生育期的需水特性及土壤水分平衡原理,建立了适合贵州省烤烟生产的烟地水分预测模型,并用实际观测数据对模拟值进行验证,效果较好。By use of the method recommended by FAO-56,the daily evaporation of reference crop in Guizhou Province was calculated.Based on the water requirement characteristics of tobacco during different growth phases and the principle of soil water balance,a drought prediction model for tobacco planting soils in Guizhou Province was established.The model results were validated by the observed data,and satisfactory agreement was achieved.
