The evaluation of a series (1961–2000) of ombrographic records from 13 selected stations of Czech Hydrometeorological Institute provided long-term annual summation values and annual peaks of the rainf...
降雨灌溉蒸发条件下苹果园土壤水分运动数值模拟（Numerical Simulation for Root Zone Soil Moisture Movement of Apple Orchard under Rainfall-irrigation-evaporation）
苹果园 土壤水分运动 数值模拟
2009/11/24
根据土壤水动力学原理和果树根区土壤水分运动特点，建立了降雨灌溉蒸发条件下含根系吸水项的二维土壤水分运动数学模型，采用有限元法求解，对降雨灌溉蒸发条件下的地表边界条件进行处理。在田间进行了灌溉蒸发条件下果园土壤水分运动验证试验，采用田间实测土壤含水率分布资料对模型进行验证，结果表明模拟值与实测值吻合较好，所建的根区土壤水分运动模型是正确的，采用有限元法求解是可行的，该模型可用于预测果园田间土壤水分运...
