| 摘 要： | 为评估AquaCrop模型在华北平原模拟大葱生长和农田水分的适用性,本研究利用实测的农民施肥方式的一个小区和增施氮肥处理的土壤水分、作物生长和产量数据,结合气象资料,获得了AquaCrop模型模拟大葱生长和土壤水分的模型参数,并利用实测的农民施肥方式的另外一个小区、减施氮肥、优化施氮和秸秆还田处理的土壤贮水量和生物量数据进行了模型验证。结果表明：在无水分胁迫条件下AquaCrop模型对大葱土壤贮水量及生物量的模拟结果是可以接受的。对土壤贮水量实测值与模拟值的RMSE为19.4~24.9 mm之间,相对误差为3.9%~12.4%;大葱生物量实测值与模拟值的RMSE为0.31~0.73 t/hm2,相对误差为5.8%~12.8%。

| Abstract: | The objective of this study was to evaluate the AquaCrop model for Chinese green onion for simulating the growth and soil water storage in North China Plain.AquaCrop model for Chinese green onion was parameterized using soil water data,crop growth and yield data from one plot of Farmer Practice and Heavy Nitrogen Application treatments and the weather data,and tested using data from another plot of Farmer Practice,reduced nitrogen application,optimized nitrogen application and straw returning treatments in ... |
