(APSIM-Wheat模型)在3种产量水平下(潜在,雨养和实际产量)的开花期,成熟期,产量,生育期的蒸散(evapotranspiration,ET)对品种,土壤和生化等33个参数的敏感性和不确定性.发现:①影响开花期和成熟期较为敏感的参数依次是:始花期积温,出苗到拔节积温,春化指数,光周期因子,灌浆期积温;②影响产量较敏感的参数依次为:...
利用内蒙古6个代表性站点的春小麦田间试验数据和同期逐日气象数据对APSIM-wheat模型在内蒙古地区的适应性进行研究,确定了10个春小麦品种的作物参数。结果表明:模拟春小麦的播种至出苗、开花和成熟各阶段天数与实测天数有较好的一致性,其均方根误差(RMSE)分别为0~1.7d,0.8~4.1d和1.0~2.8d;模拟的10个春小麦品种中,...
APSIM-wheat is a crop system simulation model, consisting of modules that incorporate aspects of soil water, nitrogen (N), residues, and crop development. The model was used to simulate above- and below-ground growth, grain yield, water and N uptake, and soil water and soil N in wheat ...

Performance of the APSIM-wheat model in Western Australia The overall APSIM model predictions of shoot growth, root depth, water and N uptake, soil water, soil N, drainage and nitrate leaching were found to be acceptable. Grain yields were well predicted with a coefficient of determination .....
In this study, we evaluated the suitability of semi-arid region of Central Morocco for wheat production using Agricultural Production Systems sIMulator (APSIM) considering weather, soil properties and crop management production factors. Model calibration
APSIM-Wheat was evaluated with the data recorded from the remaining four sowing dates. The average errors between simulated and observed values for sowing dates were 1.91%, -2.99%, -22.69%, 15.64% and 12.43% for days to anthesis, days to maturity, maximum LAI, grain yield. It was ...
